Advantages of PM Steels

Main advantages of powder metallurgical high performance steels

Advantages

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 require less machining and rework after heat treatment.

6. Cleanliness
Excellent polishing and EDM machining capabilities result from the highest possible degree of purity, known as »Ultra Clean«.

Economy Calculation PM Steels

It must be admitted that, at first sight, powder metallurgical high performance materials are relatively expensive. But often only at first sight. A detailed price/performance comparison between powder metallurgical and conventional tool steels often produces some surprising results.

An example of a cost-effectiveness study has revealed a saving of
$ 12220 by the use of Z-A11 PM material.
