These hex bars are hardened for increased abrasion and impact resistance. They are also stress relieved to reduce the chance of warping during machining. Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.
