Cobalt Special (CoSP) is a super high-grade stainless steel for cutlery that provides outstanding corrosion resistance, wear resistance, grindability, and workability achieved through a unique remelting method that results in a uniform composition and fine dispersion of carbides.
According to our data, it contains 1.1% carbon (C) and 16% chromium (Cr), exerting incomparable corrosion resistance.
Tungsten (W) improves tempering resistance, molybdenum (Mo) contributes to further improvement of corrosion resistance, and vanadium (V) enables a more refined microstructure. Cobalt (Co) strengthens the matrix and effectively maintains a long-lasting sharp edge.
The significant advantage of Cobalt Special is that the microstructure obtained by this exceptional steelmaking technique maximizes the effect of each added element.
