Tight-Tolerance Hardened Multipurpose
4140 Alloy Steel Sheets and Bars
Also known as flat stock, the thickness on these sheets and bars is held to a tight tolerance. They are hardened for increased abrasion and impact resistance. Also known as chrome-moly steel, this versatile 4140 alloy steel is used for many parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.
