AISI 1015 is a low-carbon steel used in the annealed, cold-worked, hot-rolled or normalized condition for general purpose construction and engineering. It is also used for case-hardened components. It 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 forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-48. Producer or source: Carbon steel mills.
