c75s spring steel carbon steel with high strength

c75s spring steel carbon steel with high strength

c75s spring steel is a low alloy, carbon steel material with carbon content 0.72-0.84. This material can be heat-treated to the required tensile strength, operated by annealing process (CRCA) or hardened and tempered condition (Q+T). Process engineering of heat treament is very vital to the inherent quality of spring steel strip. The edge of C75S spring steel can be rounded or slit. Underd continous hardened (810-840`C) and tempered (300-500`c) facility, the finish surface can be blue,yellow,black,etc..

Carbon	0.72-0.80%
Silicon	0.15-0.35%
Manganese	0.60-0.90%
Sulphur	0.035% max
Phosphorus	0.035% max
