the steel strip's surface Rust resistance
As the high carbon spring steel strip is according to the heating treatment with hardened and tempered based on the process optimized and equipment improved,so that make the surface of the steel strip developing a balance of blue oxide film,which can increase the surface quality and rust resistance.
Hardened and tempered steel strip of medium&high carbon steel strip(DIN CK67,CK70,CK75,CK80,SK5) is produced with a unique processing facility, quenching using oil or water process with temperature systems,the process to produce bainitic steel strip having unique combination of hardness of ductibility that improves the toughness property
