SIRAPID steel is alloyed with molybdenum and tungsten, achieving excellent hardness with both hot and cold rolling. It also provides wear and shock resistance.

Excellent hardness and shock resistance, even at high speeds and temperatures, make SIRAPID an excellent choice for various tooling applications, including cutting tools (such as knives, drill bits, and milling cutters) as well as rolls for cold rolling and other cold-work tools.
