Cobalt Special (CoSP)

Cobalt Special is a steel we highly recommend with assurance that this super excellent stainless cutlery steel, which means fulfills all the prerequisite conditions of the corrosion resistance, abrasion resistance, grindability, and workability by the refinement of primary carbides. Carbon (C) is included 1.1%, 16% of Chromium (Cr) exerts incomparable corrosion resistance among our products. Furthermore, the additional tungsten (W) helps tempering resistance, the Molybdenum (Mo) contributes to increased corrosion resistance increasing, and the Vanadium (V) makes structural refinement.

Cobalt (Co) enhances the matrix and is effective in the prevention of decarburization.
