Cold-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.
Cold-work steel is a type of tool steel that is generally resistant to application surface temperatures up to 200 °C. The strengths of cold-work steel are its high hardness, high wear resistance, good toughness, and good dimensional stability while still remaining adequately workable.
