Specifications

High Carbon spring steel wire
Tensile strength: 1370 to 1770 MPa
Better mechanical property

 

high carbon spring steel wire for  Clutch, Brake and Cushion has an excellent performance of mechanics and good surface condition . Other applications  include suspension, shaft, car cushion, bicyle springs etc. The Mn inside the steel gives a higher hardenability of steel wire. The integrated mechanical performance is better than carbon steel wire. That being said, it still have disadvantages, such as overheat sensitivity and temper brittlement. Therefore, it is usually used for all kinds of small size flat and round spring, cushion spring, power spring, brake and clutch spring and so on. The strength, hardness, elasticity and hardenability are all better than 65# steel.
