Characteristics and suitability of use
Standard high-speed steel. Due to well balanced alloy composition this steel is used for versatile applications e.g. drills, milling cutters, reamers, circular saws, wood working knives etc. In addition, steel is used in areas typical of cold work e.g. cold forming dies, cold extrusion rams, tools for stamping and fine blanking tools.
Forged blocks in quality ESU in stock. Round bars in standard quality.
