SKH9 Hitachi High-Performance High-Speed Steel Introduction to SKH9 High-Speed Steel Performance: SKH9 steel is a high-speed steel of the SKH model produced by Hitachi Metals, Japan. The grade is designated with SKH followed by a numerical sequence to distinguish between tungsten series and molybdenum series high-speed steels. The high-speed steel standard includes 13 grades. SKH9 is a tungsten-molybdenum series high-speed steel. SKH9 high-speed steel offers good toughness, wear resistance, red hardness, high-temperature strength, high-pressure strength, overall hardenability, and high hardness after heat treatment. The steel has fine and uniform carbide structure, hot and cold work plasticity, good machinability, and grindability.
