Starting as a Chicago small forge shop in 1893, today Scot Forge can forge parts weighing up to 300,000 lbs. and roll seamless rings up to 252 in diameter. Scot Forge History From Humble Beginnings Scot Forge started from humble beginnings with four brothers, looking for a better future, who traveled from the Shetland Islands in Scotland to America. They found their success in the steel industry and opened a small, six-man hammer forge shop in Chicago in 1893, under the name A. Kropp Forge. The Chicago area was booming in the 1890s, but by mid-decade a financial panic overtook the nation and in 1914, the company was bought by a group of Ryerson employees and renamed Kruse Forgings. Then, two years later, the name was changed to Atlas Forge partly as a marketing endeavor so the company would be first in the phonebook - listing are alphabetical – and by 1919, Atlas Forge moved to Cicero, Illinois. More than 60 years later a new greenfield manufacturing plant was built in Clinton, Wisconsin. This unusual plant location was due to the Cicero plant growth being hindered by a stationary noise law in Illinois. At this point, in 1977, the company name would change again to Scot Forge and a Scottish highlander became part of the corporate logo. Along with the new name came a unique sales promotional tool – the wearing of tartan apparel by the personnel. Continued growth created a need for a third manufacturing plant to be built in Spring Grove, Illinois, which became the permanent headquarters for Scot Forge. Additionally, in 1978 the owning family decided to sell the company to the Scot Forge employees starting the Employee Stock Ownership Plan (ESOP). The company continued to grow from 1985 to 1997. The Cicero plant moved to Franklin Park, Illinois, and Scot Forge formed two partnerships that turned into join ventures – Ringmasters and North American Forgemasters (NAF). Today, Scot Forge operates with more than 1.3 million sq.ft. of manufacturing space between the five plants and we ship more than 250 million lbs. of forgings annually. We are proud to be a 100% employee-owned manufacturer of custom, open die forgings and seamless rolled rings. In 1893, The A. Kropp Forge Company was little more than a blacksmith shop, where workers performed all tasks by hand. The Chicago area was booming in the 1890s, but by mid-decade a financial panic overtook the nation. Business did not recover until the outbreak of World War II. Demand continued after the war and into the Korean War in the early 1950s. This photo shows one of the large hammers placed into service. Prior to the use of modern, mobile manipulators and hydraulic presses, forging work was done by hand, with spider-like manual manipulating tools. This picture taken of Scot Forge employees in the Cicero Plant, shows that workers had to be strong, hardy and filled with stamina to handle the demands of the physical labor. The addition of this 8,000 lb. hammer with the innovative rotator allowed Scot Forge to enter the forged round bar market with the steel service centers. Plant and office staff pose for this 1948 photo. A. Kropp and Company had been incorporated as the Kruse Forgings company in 1914 and the name was changed to Atlas Forging Company in 1916. It wouldn't be known as Scot Forge Company until 1978, coinciding with the institution of the Employee Stock Ownership Plan (ESOP). Why Plaid? Well, as it turns out, Pete “Spike” Georgeson ordered one tartan jacket to help him get noticed at a luncheon… and it worked! So well in fact, that he decided he needed to order a couple more jackets, so he asked for a swatch of every tartan to decide what to order. Somewhere along the line, the tailor thought he said one jacket in every tartan. Rather than returning all of the jackets Pete decided to give them to his sales team and the rest is history.

METALLURGY FAQs We Asked The Experts Ordering a forging is not always an easy task. In fact, what is a forging? How do you kill steel? Metal has different properties? We asked our experts to explain these questions and more to empower you and your team to effectively procure a forging. WHY FORGING? FORGE ENGINEERING & DESIGN CONSULTATION Forging & Other Processes What is a forging? How does it differ from a casting? What is "grain flow"? What are the benefits of a seamless hollow-core forging? What is the optimum reduction needed for a forging? Materials What does fully killed steel mean? What grades of steel cannot be heat treated to achieve properties? What effect does lowering the temper temperature have on common alloy grades of steel? General Metallurgy Where can I find a chart to convert Rockwell HRC to Brinell HB hardness? Q: What is a forging? How does it differ from a casting? A: A forging is metal that has been heated in order to soften it then pressed, hammered, or otherwise formed into a shape. All forgings begin as cast starting stock. Forgings benefit from the forming operation which enhances their overall toughness and fatigue resistance. Back to top Q: What is "grain flow"? I've heard "grain flow" mentioned on several occasions when discussing forgings. What exactly is "grain flow" and what does it do (or not do) for me? A: Forgings are produced using the open die forging process through the controlled application of compressive stresses while the metal is heated in the plastic regime. The metal, once subjected to the compressive stress, will flow in any unconstrained direction. The expanding metal will stretch the existing grains and, if the temperature is within the forging temperature region, will recrystallize and form new strain-free grains. This results in even better resistance to fatigue and stress corrosion than a forging that does not contour the component. Other contributors to grain flow are the expansion of microsegregated regions and/or inclusions in the direction of the metal flow. The effect of the elongated microsegregated regions and/or inclusions can be controlled through the use of high-quality material and due attention to the forging technique. Back to top Q: What are the benefits of a seamless hollow-core forging? What are the benefits, with respect to residual stresses, of a seamless hollow-core forging over rolled and welded plate that is subsequently processed (machining, heat treating, etc.)? A: In general, distortion of a component will occur when the stress states of either the individual components or the assembly as a whole shift from one state of equilibrium to a new equilibrium state. The presence of residual stresses in the components act as a source of potential energy similar in nature to a spring fixed in a compressed state. If the fixture holding the spring remains intact, the spring does not expand. However, once the fixture is removed, the spring expands until it reaches a new state of equilibrium—either another fixed point or a point where the potential energy of the spring is expended—and the spring is extended. So, too, will the potential energy in a component due to residual stress remain unchanged until the equilibrium state is altered—either through mechanical means (metal removal or cold/warm straightening, etc.) or thermal means (welding, heat treatment, etc.). Using this model, it is apparent that the key to minimizing distortion is to select a fabrication process that (1) uses input material with little or no residual stress and (2) will permit a subsequent processing path that introduces as little residual stress as possible. To form a plate into a cylinder, in most cases, it will require stretching the metal beyond its yield point to both hold the cylindrical shape and allow for the subsequent spring-back. If it is assumed that the starting plate is essentially free of residual stress due to processing at elevated temperatures (a large assumption, indeed), the equilibrium state of the plate is subsequently changed during rolling through the introduction of tensile and compressive stresses that shift the equilibrium state to that of a cylindrical shape (requiring a weld to hold it in place because of the tendency to spring back, in particular with materials having a high yield strength). Understanding the proportional relationship between stress and strain (elastic modulus), it can be intuitively understood that the stretching will spring back to a new state that now has residual stress present. In addition, the introduction of the longitudinal weldment to complete the cylindrical shape further disrupts the system through the introduction of thermal energy. The severity of the residual stress will increase with increases in either, or all, of the yield strength of the base metal, circumference of the tube and plate thickness. Once the desired shape is achieved, it will remain in that shape as long as no subsequent processing or service conditions that alters the stress state is performed (machining or welding, for example). When the part does distort, additional mechanical work is required to revive the desired shape, resulting in an often "circular" manufacturing path. These costs are often not considered when selecting a rolled and welded cylinder. Consider, now, a seamless hollow-core Scot Forge forging that is forged at elevated temperatures with dynamic recrystallization (the immediate formation of stress-free grains upon deformation). The stresses introduced during forging to produce the cylindrical shape are immediately removed through the recrystallization of the crystal structure, resulting in an essentially stress-free forging. Consequently, a rolled and welded assembly possesses significantly higher residual stress than a forged seamless cylinder (hollow-core). Furthermore, no thermal stresses from welding are introduced during formation of the cylinder as a seamless forged hollow-core, unlike the rolled and welded plate method. To summarize, the Scot Forge seamless hollow-core forging is far more stable and possesses a higher degree of structural integrity (no welds!) than a rolled and welded cylinder assembly for an often lower overall cost. Back to top Q: What is the optimum reduction needed for forging? A: Forging reduction should be sufficient to consolidate the defects inherent to the casting process such as porosity and other voids while achieving a general wrought structure by breaking down the cast structure. A 3-to-1 reduction, using the open die process, is usually sufficient to achieve these results (with strict control of the process, less than 3-to-1 can be sufficient). Depending on the alloy and customer requirements, higher reduction may be necessary to achieve certain additional mechanical or physical requirements. Back to top Q: What does fully killed steel mean? I see that a specification required by my customer is that the steel shall be fully killed. What does that mean, and why would they need that? A: Killed steel is steel that has been treated with a strong deoxidizing agent during the melting process. The elements typically used are aluminum and/or silicon. Both have a strong tendency to form oxides which are floated out during the melting process, which reduces the overall oxygen content in the steel. If oxygen remains in the steel in large amounts, the steel is much more susceptible to defect formation during the forging process. The excess oxygen can also form oxide particles in conjunction with iron and manganese, which reduce the notch toughness and impact resistance of the steel. This can adversely affect the life of the finished part. Back to top Q: What grades of steel cannot be heat treated to achieve properties? A: Non-heat treatable grades of steel are those which cannot have their mechanical properties modified due to heat treating. They achieve their mechanical properties through a combination of chemistry selection and forging method. Back to top Q: What effect does lowering the temper temperature have on common alloy grades of steel? A: In general, tempering temperatures are inversely related to strength and hardness and directly related to ductility and toughness. Back to top Q: Where can I find a chart to convert Rockwell HRC to Brinell HB hardness? Can you direct me to an engineering materials resource that provides charts for steels that display Tensile/Yield Strength vs. hardness? A: We faced the very same question when compiling the data for one of our charts on our website. The hardness conversion among HB, HRC, HV and many others can be found in ASTM E140. We're sure you noticed, as did we, that the specification does not contain a conversion to an equivalent tensile strength. We therefore found the correlation in the ASM reference book as noted at the bottom of the chart. We are not aware of such a correlation for aluminum.

Downstream processing such as heat treatment, testing, machining, segmenting, parting or splitting can all be performed in-house Guaranteed delivery programs OPEN DIE RINGS ROLLED RING ADVANTAGES At Scot Forge, we produce seamless rolled rings using an open die forging method or our ring rolling mill. Forged seamless rings are incredibly durable and reliable because they have inherent, circumferential grain structures and no weldments, eliminating weak points. Our seamless ring rolling mill is also a more cost-effective forging process than other methods because less starting stock is required to manufacture the ring. As a result, there is less material to machine away from the end product, another added benefit. When combined with a ring expander, ring rolling generates exceptionally round and durable ring products in any forgeable material. Seamless Ring Rolling Process The seamless rolled ring forging process starts with heating a pre-cut billet, then the malleable metal is placed on a hammer or press. The ring shape begins with a centerpiece "snapped" from the pre-form to produce a hollow center, similar to a donut, and moved to the ring mill. Once on the ring mill, the center of the part supported by a mandril and rollers apply pressure from different angles to gradually expand the ring. Rings made on a press are placed on a pin, supported by a saddle, then rotated as force is applied to expand the opening. Both techniques create circumferential grain flow creating the desired dimensions of the forged ring. This is our high-tonnage Wagner ring mill and ring stretcher in action! The Wagner allows us to produce: Straight rolled rings Contoured rolled rings The additional processing on our custom-engineered ring stretcher/sizer helps to minimize stock allowances, improve concentricity and cold-work aluminum rings.

Open Die Forging Capabilities Forging Expertise Equipment means nothing without the experience, expertise and passion of our team. This passion drove Scot Forge employee-owners to custom engineer and build our hydraulic presses. Coupled with the industry's largest ring and planishing mills, we can produce high-quality open die, seamless rolled rings and bar forgings. On an annual basis, we invest a significant amount of capital back into our business to improve and expand operations, all based on our customers’ needs. HAMMER FORGING IN ACTION PRESS FORGING IN ACTION Press Forging Advantages Our employee-owners have decades of experience and the skills to produce complex open and semi-closed die forgings. Additionally, we can produce parts weighing a couple of pounds up to 300,000 lbs. in a wide range of ferrous and non-ferrous materials – redundant press capacity provides added assurance for time-critical applications. Our presses are engineered and built in-house. This design expertise gives us ultimate flexibility and speed throughout the forging process. Hammer Forging Advantages We combine the versatility of pneumatic hammers with state-of-the-art heating and manipulating equipment to produce blank, ring, dumbbell, single and double hub forgings in a wide range of shapes and sizes with more than 10,000 loose tools. Our extensive tooling capabilities and years of experience enable us to offer low-volume prototypes and fast turnaround, often providing a superior value solution as opposed to machined bar stock, weldments or closed die forgings - and save you on tooling investments. Ring Rolling Advantages Scot Forge can provide seamless rolled rings in single-piece or high-volume quantities as large as 252” O.D., 49" face height with weights up to 65,000 lbs. Our high-tonnage Wagner ring mill, along with three other in-house ring rolling mills, allows us to produce straight or contoured rolled rings and our custom-engineered ring stretcher/sizer helps to minimize stock allowances, improve concentricity and cold-work aluminum rings. Bar Rolling & Bar Planishing Advantages Scot Forge offers finish rolling (or planishing), which begins as the forged bar goes through one of the four hyperbolic grooves of our custom-engineered GFM bar mill. The desired final dimension is reached after a series of bar rotations and passes through the mill. The bar rolling/planishing process produces Tartan Bars®, a unique bar product offered only by Scot Forge. These bars are produced by combining a preliminary forging process, consolidating the center with a planishing operation, which provides a smooth rolled surface. We can offer Tartan Bars from 6" to 16". Larger precision forged bars up to 63" in diameter can be manufactured on our open die presses.
