tool steel Product Introduction
AISI 6542 high-speed steel is a typical tungsten-molybdenum high-speed steel. Its toughness and wear resistance are better than W18Cr4V, and its hardness, red hardness and high temperature hardness are high. It can be used to manufacture various tools, general tools and thermoplastic molding tools that can withstand large impact forces. It can also be used for high-wear wearing parts and cold work molds.
