SKS51 steel is a common alloy tool steel, valued for its good combination of toughness and wear resistance. Its key SKS51 properties are developed through heat treatment, which imparts high hardness suitable for cutting and forming tools. The addition of nickel and chromium makes this SKS51 material tougher than standard carbon steels.
Due to its balanced performance, it is frequently used for industrial knives, saw blades, and cutting tools.
