Steel alloy contains carbon (in wt.%) (2.05-2.65), silicon (up to 2), manganese (up to 2), chromium (6.1-9.8), tungsten (0.5-2.4), molybdenum (2.15-4.7), vanadium (7.05-9), niobium (0.25-2.45), cobalt (up to 10), sulfur (up to 0.3), nitrogen (0.04-0.22), nickel (up to 1.5), oxygen (less than 100 ppm) and iron (balance) and non-metallic inclusions with maximum k0 value of 3 according to DIN 50602. <??>The cold work steel alloy contains carbon (in wt.%) (2.05-2.65), silicon (up to 2), manganese (up to 2), chromium (6.1-9.8), tungsten (0.5-2.4), molybdenum (2.15-4.7), vanadium (7.05-9), niobium (0.25-2.45), cobalt (up to 10), sulfur (up to 0.3), nitrogen (0.04-0.22), nickel (up to 1.5), other elements (up to 2.6), oxygen (less than 100 ppm), iron and impurities (remainder) and non-metallic inclusions having k0 value of maximum of 3 according to DIN 50602. The steel alloy is used for forming component with high degree of toughness, hardness and resistance to wear and material fatigue. <??>An Independent claim is included for manufacture of tool or component, by powder metallurgy. |
