Stellspur PM 10 is a grade designed for high abrasive wear applications
like wood and paper knifes.

Characteristics

Stellapur PM 10 is a high V alloyed grade
for improved wear resistance. A suitable
grade for cold work applications, knifes
and other abrasive wear parts. The grade
can easily be wire cut. Recommended for
PVD/CVD coating. For nitriding max
2-15 µm is recommended.

Typical applications:
Cold work tools
Knifes
Wood and paper tools
