Specially: Tungsten high speed steel, high hardness hot hardness and high temperature strength, a wide range of heat treatment, not easy to abrasive machining, difficult of oxidation of decarbonization in the process of hot working or heat treatment. The carbide inhomogeneity and high temperature plastic are poorer than molybdenum. But the wearing resistance is better. Use: For manufacturing all kinds of free cutting tools. Heat treatment: Quench : 1270- 1285?C oil coolingTempering : temperature 550- 570?C, hardness 63HC Dimension ( mm ) : Round : diameter50- 300 mm Flat : thickness20- 200 mm *width60- 500 mm
