Hot-work steels
Logically speaking, selecting the best materials requires outstanding experience and specific expert knowledge, both of which Friedr. Lohmann GmbH has gained over the course of two centuries.
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.
