1144 Carbon Steel Data
1144 is a standard resulphurized medium-carbon steel (AISI 1029-1053, 1137-1151, and 1541-1552) that can be heat treated to have a good balance of ductility and strength.
These steels are typically used in large parts, forgings, and machined components.Bolts, rods, crankshafts, and tubings in the automotive industry are generally made of AISI 1040 and its modifications. Axles, gears, and components that require higher hardness and wear resistance are frequently made of AISI 1050.
