==Original Abstract Submitted==

a high speed steel composition and article are disclosed consisting, in weight percent, essentially of about 0.75% to 1.69% carbon, 0.15% to 0.80% manganese, 0.20% maximum phosphorous, 0.25% maximum sulfur, 0.20% to 0.65% silicon, 3.75% to 4.50% chromium, greater than 10.00% to 20.00% tungsten, greater than 1.25% to 4.21% molybdenum, 4.00% maximum vanadium, 4.00% maximum columbium, 12.00% maximum cobalt, 0.010% to 0.090% nitrogen, 0.75% maximum copper, 0.75% maximum nickel, 0.25% maximum aluminum and balance iron with residual elements and trace impurities in normal amounts, the composition and article being characterized by very high hardness capability and wear resistance. the high speed steel article is preferably manufactured via powder metallurgy by dispersion of a liquid metal stream of the alloy with nitrogen gas to form metal powder. this metal powder may be utilized in metal additive manufacturing applications and is suitable for applications involving chip cutting machining, or advanced machine elements.
