Fushun CK75 Cold Rolled High Carbon Steel Strip

Product Information

Fushun Metal offers a wide variety of spring steel products to meet your specifications. Spring steel refers to steel, normally of the high carbon or alloy type, used in the manufacture of springs. the steel is processed by cold drawing, cold rolling, or heat treating to give it the elastic properties and yield strength required in springs.
Spring steel is often used because of its high yield strengths, resistance to deformation, and its ability to return to its
Original shape. Our spring steel and spring steel strips are available as heat-treatable annealed, which allows the forming to occur prior to the heat treatment, or heat treated, where the steel is previously hardened, tempered, or sprung. Our inventory of annealed spring steel can be easily formed, tempered, heat treated, blanked or shaped.
