AISI 1524 is a low-to-medium carbon steel combining good workability, good machinability and good weldability. It is used in the hot-rolled, annealed, normalized, cold-worked or water-quenched-and-tempered condition for a variety of applications. It is also used for parts case-hardened by carburizing. It has a high manganese content (1.35-1.65%) to provide increased hardenability which is reflected in all uses and gives increased strength and hardness in the core of carburized parts and in uncarburized applications. 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-61. Producer or source: Carbon steel mills.
