AISI 1018: Case Hardening and General Purpose Steel

AISI 1018 is a carbon steel with a relatively high manganese content (0.60-0.90%) which provides increased hardenability in all applications and increased hardness and strength in the core of carburized parts and in uncarburized uses. AISI 1018 combines good machinability, good workability and good weldability. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-56. Producer or source: Carbon steel mills.
