Difference between high speed steel and tungsten steel
High speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as wind steel or sharp steel, meaning that it hardens when quenched even when cooled in air and is sharp. It is also referred to as white steel.
High-speed steel is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, but also high-temperature bearings and cold-extrusion molds, such as turning tools, drills, hobbers, machine saw blades and demanding molds.
Tungsten steel (Cemented Carbide) has a series of excellent properties such as high hardness, wear resistance, better strength and toughness, heat resistance, corrosion resistance, etc. Especially its high hardness and wear resistance, even at a temperature of 500 ℃ is basically unchanged at 1000 ℃ still have a very high hardness.
Tungsten steel, the main components of tungsten carbide and cobalt, which accounts for 99% of all components, 1% of other metals, so called tungsten steel, also known as tungsten carbide, is considered to be the teeth of modern industry.
