M390 Böhler 2,3x35x500mm

Böhler M390 Microclean (optimal alternative to CPM S 90 V)

Powder metallurgically produced martensitic chrome steel with the highest wear resistance and toughness

Large proportions of small, finely distributed Cr and V carbides in the base material offer maximum corrosion resistance, best wear resistance and excellent polishability at the same time.

Use: high-performance cutting tools, knife blades

C: 1.9 Si: 0.70 Mn: 0.3 Cr: 20 Mo: 1.0 V: 4.0 W: 0.6

Delivery condition:

-heated / cross-rolled

- soft annealed

-Width laser cut, length sawn (thus no bending / curvature due to the cutting process!)
