Powder metallurgical steel

Our principals Zapp Precision Metals GmbH Tooling Alloys, member of the Zapp-group, are European distributors of CPM® powder metallurgical tool steels from Crucible Industries (USA). These materials represent the optimum in steel technology. Thanks to the special manufacturing process, powder-metallurgical steel fulfills the highest requirements. PM steel often greatly improves machine service life.




Higher alloy levels can be manufactured while maintaining good mechanical characteristics.


The uniform distribution of carbides and absence of metallurgical defects improve fracture and fatigue strength.


Higher carbide volume increases resistance to both abrasive and adhesive wear.


Machining ability is improved as a result of the small globular carbides.


PM steels are free from segregation leading to substantially improved dimensional stability.


The highest possible degree of purity, “ultra-clean”, results in excellent machinability and outstanding erosion properties.



Is a tough, wear resistant hot work steel with a high hardness potential.
Blanking and punching, even for thicker sheet metals. Hot heading dies, dies and forging tools, thread rolling tools, plastic injection dies and inserts, extrusion moulding.


Cold work tool steel with high toughness and wear resistance.
