Alloy Steel Manufacturing Companies in the U.S.

U.S. machine shops, fabricators, foundries and other manufacturers whose own descriptions mention alloy steels such as 4140, 4130, 4340 or 8620. Confirm grades, stock and capabilities with the shop.

Listings come from each company’s public information and may be incomplete, so confirm capabilities, materials and certifications with the shop before you commit. The fastest way to get quotes is one request: attach your drawing (PDF or STEP) or describe the part, and Noramark routes it to U.S. shops that fit.

The most listings are in Texas (12), California (10), Michigan (9) and Ohio (7). Certifications stated: 25 ISO 9001, 10 AS9100 and 1 IATF 16949.
