Powder-metallurgical tool 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.
Harder, tougher, more resistant to wear - tool steels manufactured using the powder metallurgy process allow the highest possible alloy content with no major restrictions to the mechanical properties, in contrast to comparable conventional alloy levels. Due to the complex manufacturing process required, a homogeneous structure free of segregation and defects is produced.
Powder-metallurgical steels are characterized by high toughness, the highest possible wear resistance, high processing hardness, and long tool lives.
