JIS G4051 S25C steel

JIS G4051 S25C steel

JIS G4051 S25C steel is a grade in JIS standard, it is similar with Chinese grade 25#. S25C is high-quality carbon steel. S25C’s carbon content is lees than 1.35% and S25C does not contain other alloy element, except iron, carbon and limited silicon, manganese, phosphorus, sulfur and other impurities.S25C properties mainly depends on the carbon content.Higher carbon content, lower strength of steel, hardness, plasticity, toughness and weldability for JIS G4051 S25C steel.

JIS G4051 S25C is suitable for medium such as water, steam, air, hydrogen, ammonia, nitrogen and oil products under nominal pressure PN≤32.0 MPa and the temperature is 30-425 ℃.
