Scot Forge

What Scot Forge does

Scot Forge is a privately held, 100% employee-owned (ESOP) metal forging manufacturer founded in 1893 and headquartered in Spring Grove, Illinois, with additional manufacturing facilities in Clinton, Wisconsin, and Franklin Park, Illinois. The company specializes in open die forgings and seamless rolled ring forgings produced in weights ranging from a few pounds up to 440,000 lbs, using hydraulic presses (3,000/2,000/1,250 ton), pneumatic forging hammers, seamless rolled ring forging mills, and a proprietary GFM single-stand planishing mill that underpins its trademarked Tartan Bars product line. Its process technology is supported by in-house simulation and modeling software used to engineer near-net shape forgings with reduced machining requirements and improved mechanical properties.

The company serves enterprise and government customers across aerospace, defense, mining, power generation (including nuclear and SMR components), shipbuilding, semiconductor manufacturing equipment, oil & gas, and infrastructure. Scot Forge's go-to-market is direct enterprise field sales through technically trained account managers and sales engineers who provide forge design consultation and custom quoting; pricing is quote-based per order and the company sells no off-the-shelf catalog product. End customers include NASA, the U.S. Navy (Columbia, Virginia, Seawolf, and Los Angeles class submarines), the U.S. Military (M1 Abrams, Nimitz and Ford class carriers, Arleigh Burke destroyers), and commercial aerospace, mining, and shipbuilding manufacturers.

Scot Forge generates revenue through custom one-time project orders for engineered forgings, with revenue mechanics tied to material type, forging complexity, weight, quantity, and processing requirements such as heat treatment, machining, and testing. Standard payment terms are 30 days net from invoice. The company holds an unusually broad certification stack for an open-die forger — ISO 9001:2015 (held since 1992, the first in North America), AS9100D, Nadcap (Heat Treatment for aluminum and NDT), ABS, DNV, Lloyd's Register, ITAR, PED, and OSHA SHARP — which is the primary barrier to entry in its regulated end markets. Two jointly-controlled entities, Ringmasters (quick-turn rolled rings) and North American Forgemasters (over-sized forgings exceeding 300,000 lbs), extend capacity beyond the in-house footprint, and a 2026 DOE grant of approximately $12.3 million is funding manufacturing equipment for advanced light-water small modular reactor components as part of the federal Generation III+ SMR Pathway to Deployment Program.
