SHK55 Molybdenum High Speed Tool Steel Product Introduction
SKH55 is a Japanese high-speed tool steel. SKH55 tungsten-molybdenum series generally contains cobalt-containing high-speed steel. It has improved red hardness and high-temperature hardness, improved wear resistance, and has better machinability.
SKH55 cobalt-containing high-speed tool steel is based on general high-speed tool steel and adds a certain amount of cobalt, which can significantly improve the hardness, wear resistance and toughness of the steel; it has certain high-temperature mechanical properties, thermal fatigue, thermal conductivity and wear resistance. Corrosion properties, etc.
SKH55 is generally used as gear cutters, milling tools, punches, cutter heads and other tools for cutting hard materials. It is not suitable to make high-precision and complex tools. This steel has lower strength and toughness and is more expensive.
