PM – high performance steel
Positive effects of the uniform microstructure for best cutting edge stability.

Conventional high speed steel
Carbide clusters near the cutting edge produce micro- and macro-chipping.
1. Alloys
The highest alloy levels can be achieved without any adverse effect on mechanical characteristics.
2. Toughness
The uniform distribution of carbides and absence of metallurgical defects increase security against fracture and fatigue strength.
3. Wear resistance
The volume and hardness of the carbides increase resistance to abrasive and adhesive wear.
4. Grindability
Machining ability is improved as a result of the small globular carbides.
5. Dimensional stability
Powder metallurgical steels are free of segregations. This leads to substantially improved dimensional stability. Tools need less remachining.
6. Cleanness
Excellent polishing and EDM machining capabilities result from the highest possible degree of purity, known as »Ultra Clean«.
