JIS G4051 S15C steel specification: JIS G4051 S15C steel standard specifies the carbon steels for machine structural use.
S15C steel often used in the manufacture of stamping parts and carburized parts, such as stamping products, sleeve, enamel products, automobile shell and wear-resisting, high strength, more stress, friction under the working conditions and requirements quite elastic parts and so on.
