AISI/SAE 5160 Carbon Steel Bar Description
5160 alloy steel is a high carbon spring steel with a small amount of chromium added in addition to carbon. The addition of chromium can improve the hardenability of steel. 5160 steel has excellent toughness, ductility and fatigue resistance. Although various properties such as wear resistance are excellent, it is famous for its excellent toughness. 5160 steel bars are used in the vehicle and tractor industry to make leaf springs with heavy loads and large stresses and coil springs with larger diameters.
