4d1ba41c-9f57-4a8a-b695-d91308a86716 TORCH OR PROFILE CUT FORGING Uniquely Shaped Forgings In Numerous Configurations We frequently combine torch cutting, sawing and machining techniques with the forging process to produce uniquely shaped, high-quality parts without costly tooling investments. We torch cut special shapes or contours into carbon and alloy forged parts, in thicknesses up to 32". Lower Costs & Lead Times Torch cutting to near-net shape saves material and machining costs, and by combining torch cutting with the forging operation, you also get the integrity of forging without the cost and long lead time often associated with other metal working processes. Torch Process Highlights Our torches can cut through carbon and alloy forgings with pre and post-heating operations that minimize thermal shock and protect forging integrity.

Mechanical & Nondestructive Testing SCOT FORGE TESTING CAPABILITIES Ensuring Forgings Meets Order & Specification Requirements Nondestructive testing processes are examinations that don't destroy the part nor compromise its soundness, making it a cost-effective testing option for forgings. From time-to-time, however, more information is needed, requiring destructive testing. These tests do destroy a piece of the forging but provide more data and yield details that are easier to interpret. FORGING EXPERTS Let us supplement your team and help you determine what the best way to go about testing your forging. Our technically trained sales team can help you find ways to incorporate your test pieces into the original forging saving you material costs. Being well versed in most forging specifications, we also help you avoid missing NDT processes to keep your project on track and your shop turning chips.

Seamless Rolled Ring Forging Process Forging Efficient Seamless Rolled Rings The production of seamless forged rings is often performed by a process called ring rolling on rolling mills. These mills vary in size to produce forged rings with outside diameters of just a few inches to over 300 inches and in weights from a single pound up to over 300,000 pounds. What is Rolled Ring Forging? The ring rolling process starts with a circular preform of metal that has been previously upset and pierced (using the open die forging process ) to form a hollow “doughnut.” This doughnut is heated above the recrystallization temperature and placed over the idler or mandrel roll. This idler roll then moves under pressure toward a drive roll that continuously rotates to reduce the wall thickness, thereby increasing the diameters (I.D. and O.D.) of the resulting ring. Seamless rolled rings can be produced in configurations ranging from flat, washer-like parts to tall, cylindrical shapes, with heights ranging from less than an inch to more than 9 feet. Wall thickness to height ratios of rings typically range from 1:16 up to 16:1, although greater proportions can be achieved with special processing. The simplest and most commonly used shape is a rectangular cross-section ring, but shaped tooling can be used to produce seamless rolled rings in complex, custom shapes with contours on the inside and/or outside diameters. Producing a ring "preform" by the open die forging process: 1. STARTING STOCK FIRST ROUNDED, THEN UPSET Starting stock cut to size by weight is first rounded, then upset to achieve structural integrity and directional grain flow. 2. WORKPIECE IS PUNCHED, THEN PIERCED Workpiece is punched, then pierced to achieve starting “doughnut” shape needed for ring rolling process. 3. READY FOR PLACEMENT ON RING MILL FOR ROLLING Completed preform is ready for placement on ring mill for rolling. Rolled ring forging process: 4. RING ROLLING PROCESS BEGINS WITH THE IDLER ROLL Ring rolling process begins with the idler roll applying pressure to the preform against the drive roll. 5. RING DIAMETERS ARE INCREASED Ring diameters are increased as the continuous pressure reduces the wall thickness. The axial rolls control the height of the ring as it is being rolled. 6. DESIRED SIZE IS ACHIEVED The process continues until the desired size is achieved. Scot Forge Difference At Scot Forge, we know the importance of getting your parts on-time, as expected.

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.
