Powder high speed steel has high hardness (HRC63-70). Excellent wear resistance and corrosion resistance, good toughness, excellent compressive strength. Widely used of the manufacture of heavy load stamping die, aviation high temperature bearing, and make of the special heat resistant and wear- resistant parts.
