UNS G10370 is a medium carbon, plain carbon steel. In bar form the steel is often used in the as-hot rolled condition. Cold drawn bars have attractive combinations of mechanical and dimensional properties and are widely used in mass production of machined and other parts. UNS G10370 is also used as a structural plate steel. See also Alloy Digest CS-124, May 1990. 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, and joining. Filing Code: CS-127. Producer or source: Carbon steel mills.
