Powder metallurgical steel “PM” steel is particularly versatile due to its nature. As the name suggests, the powder, e.g. vanadium, tungsten or chromium, is isostatically pressed. This creates a more uniform steel structure, which is much more resistant and more mantle-containing than conventional tool steel.

The field of application of the corrosion-resistant PM steel cutting rotor is in the production of unfilled and filled polymers
