Forging Economic Advantages Near-Net Shape Saves You Time & Money Unmatched knowledge equals unmatched forgings. Every member of our sales team receives rigorous training on forging and forging capabilities. Some have first-hand experience in the shop, which, coupled with our product and forge engineers' expertise, allows Scot Forge to create forgings that save you material costs and machining hours. Cost reduction 1. MATERIAL SAVINGS Forging can measurably reduce material costs since it requires less starting metal to produce many part shapes. For example, with a torch cut part (A), all corner stock and the full center slug are lost, even though you pay for the excess material. With a forging (B), the part is shaped to size with minimal waste. 2. MACHINING ECONOMIES Forging can also yield machining, lead time and tool life advantages. Savings come from forging to a closer-to-finish size than is capable by alternative metal sources such as plate or bar. Less machining is therefore needed to finish the part, with the added benefits of shorter lead time and reduced wear and tear on equipment. 3. REDUCED REJECTION RATES By providing weld-free parts produced with cleaner, forging-quality material and yielding improved structural integrity, forging can virtually eliminate rejections. 4. PRODUCTION EFFECIENCIES Using the forging process, the same part can be produced from many different sizes of starting ingots or billets, allowing for a wider variety of inventoried grades. This flexibility means that forged parts of virtually any grade can be manufactured more quickly and economically.

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.

FORGING CONVENTIONAL ENERGY COMPONENTS Renewable Energy OEMs Are Forging The Future With Scot Forge At Scot Forge, we know how critical component reliability is to this sector of the energy industry. When companies extract, store, pipe or ship these fuels worldwide, the environment depends on critical components performing as expected when needed. We create precision-crafted, Forged Solutions, which our customers use when quality can’t be compromised. Many aspects of nonrenewable energy demand parts to withstand unforgiving environments with no room for error or failure, which is why OEMs turn to Scot Forge. TURBINES FORGE ENGINEERING Fossil fuels provide heat, light, electricity and many ingredients for things we use every day, such as plastics. They are relatively inexpensive to extract and, according to the Central Intelligence Agency, the world generates more than 66% of its electricity from fossil fuels and another 8% from nuclear energy. Energy Industry Forged Parts At Scot Forge, we can forge shapes for every portion of the conventional energy process. From mining and drilling to converting, shipping and storing conventional energy from natural resources, we forge generators, compressors, gearboxes, heat exchangers, blowers and more. Shafts: connecting rods for large diesel engines, industrial gas turbines and control rod drive mechanisms (CRDMs) Hollow Tubes: energy storage casings, reactor pressure vessels (RPVs), boiling water reactors (BWRS), nuclear waste storage containers and small modular reactors (SMR Discs & Blanks: nuclear grid blanks and industrial gas turbines, impellers, tube sheets and nozzles Complex Shapes: Nuclear waste storage container hatching Additional Shapes: Casings, spacers, centrifuge bowls, bearing blocks, shells and transition cones Rings: pump bearings and seals, Inconel end rings, crane gears Oil & Gas Extracting, such as deep-sea drill or fracking, and refining, such as petrochemical or oil refinement, require components to withstand high heat, pressure and corrosive environments during these processes, making forgings an ideal choice for the Oil & Gas industry power production. As crude oil is a fossil fuel that's used to make gasoline, diesel fuel, jet fuel, heating oil, lubricating oils and asphalt, our team understands that on-time delivery can be just as critical as part reliability. From ram and annular blowout preventers (bodies, doors/bonnets) to pinions and bull gears, our forgings exceed expectations. Natural Gas Mining natural gas is a process that looks the same as drilling for oil. Rock formations that contain natural gas deposits are drilled into until the gas deposit is located, with different places containing different types of natural gas: Conventional natural gas is in large cracks and spaces in rock formations Shale gas or unconventional natural gas is in tiny pores within rocks Associated natural gas is in crude oil deposits Freshly mined natural gas contains natural gas liquids (NGLs) like ethane, propane, butanes, pentanes and water vapor. This wet natural gas is then processed to remove the NGLs from the methane, which is then used for fuel. From drill heads for mining gas to hollow tubes for piping natural gas, our decades of experience, along with the time-tested relationships we have built with finishing shops, gives us the ability to help you reduce your material costs and allow us to support you and your timelines. Nuclear Power Nuclear power is the energy derived from a component of uranium called U-235. While uranium is not a fossil fuel because it is a common metal found in rocks, it's still considered a nonrenewable resource because U-235 is a rare uranium component. Our forgings support projects from nuclear reactor components and small modular reactors (SMRs) to radioactive waste storage and transport with unwavering reliability for the most critical applications. From new projects or maintenance to critical or time-sensitive situations, we understand the criticality of getting your parts to you on time with 100 percent compliance to the purchase order. Coal Even as the world moves toward renewable energy, coal is still one of the top energy-producing resources in the world, second to oil. On the other hand, in terms of electricity, coal generates more than 23 percent of the world's electricity mix, according to OurWorldData.org. There are four types of coal: Met Coal (Coke Coal) Anthracite coal with the highest heating value contains 86-97 percent carbon and is used in the metals industry. Bituminous coal is the most copious type found in the United States and contains 45-86 percent carbon, often used to generate energy and make iron and steel Thermal Coal Subbituminous coal with the lowest heat value contains 35-45 percent carbon. Lignite coal has the most moisture and lowest energy content; it contains 25-35 percent carbon and is used to generate electricity. With expertise in forging components for mining, which are found in the biggest trucks globally, draglines and electric rope shovels, along with competencies in concrete and asphalt industries, we offer a partnership that includes more than just manufacturing. We have the engineering skills to keep the mines running and the energy flowing. On-Time Delivery - Our Priority With a long history of working in the industry, we understand how crucial on-time delivery can be. The Scot Forge Power Generation Services Team is well-versed in the pre- and post-award requirements, from material-process plans to NDE procedures. We know the right steps to take in order to deliver your product on time. Emergency Response Our Power Generation Services Team knows that in times of unplanned outages or critical situations, thousands—if not millions—of dollars can be lost each day. As a result, we have established an emergency response program that allows for daily entry of breakdown and rush orders for immediate production response. A Vast Inventory of Materials We maintain an extensive inventory of ferrous and non-ferrous materials and can quickly provide vacuum degassed air melt, ESR or VAR for improved cleanliness levels. Our parts are supplied using the highest-quality material available. Power generation-specific materials include carbon, alloy, stainless steel, copper base, nickel base and custom-melt alloys that meet OEM specifications. Flexible Sizes, Shapes and Quantities No matter the grade of material or shape and size of the part, our facilities are designed to support both single-piece and high-volume manufacturing. Questions?
