COLD WORKING STEEL: TOOLS & ALLOY STEEL
Cold-work steels have high chromium contents. They ensure high surface hardness, good toughness and compressive strength, and provide excellent wear resistance. Typical applications include cold-work tools, cutting-off tools, rolls for cold rolling, measuring tools, etc
Suitable to cut all types of alloy steel, it has High Toughness and good cutting properties.
Cutting parameters which has high tensile strength, Tungsten in this tool steel makes it easy to cut them - hardness upto 64-67 HRC post heat treatment.
