High-speed steel

The cutting materials and tools made of high-speed steel play a dominant role in the metalworking industry in particular.
High-speed steel is characterized by high wear resistance, a high processing hardness, adequate toughness, high resistance to tempering, and high red hardness, and can withstand operating temperatures of up to 600 °C. They are used primarily in tools used in machining or cutting processes.
