AISI 1551: High Manganese Carbon Steel

AISI 1551 is a medium-carbon steel containing relatively high manganese (0.85-1.15%) for a carbon steel. It can be used in the hot-rolled, annealed, normalized, cold-worked or liquid-quenched-and-tempered condition for numerous applications. It has a combination of good machinability and good workability. Its many uses include hand tools, machinery parts, springs and agricultural machinery. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-80. Producer or source: Carbon steel mills.
