Cobalt Special屬高階不鏽鋼材(碳含量1.1%﹑鉻含量16%﹑鈷含量2.5%)。
有著極佳的耐久度﹑抗鏽及抗酸性能。

Cobalt Special 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 finer microstructure. Cobalt (Co) strengthens the matrix and is effective in maintaining a long-lasting sharp edge.
