S290 is a powder metallurgy produced high speed grade with a composition between carbide and high speed steel. The hardness is up to 70 HRC. In addition to hot hardness and good wear resistance, compressive strength is one of the most important properties. There is a slight ferritic edge zone (edge decarburisation).
The average chemical composition is
- 2,00 % C
- 3.80 % Cr
- 2.50 % M
- 5,10 % V
- 14,30 % W
- 11.00 % Co
Etching was performed with 3% Nital for 10 seconds.
