Processing over large sintering windows of nett shape high speed steel parts and tools

Process friendly powder metallurgy high speed steel type alloys have been developed for metal cutting and wear resistance. Nett shape processing is by water atomization and vacuum and atmosphere sintering at temperatures near 1180 C over sintering windows extending to 40 C (in contrast to those of standard alloys which are 2 to 10 C). Wear and cutting properties are attractive. In single point turning of steel, performance of 2 novel sintered alloys is comparable and superior to wrought M2 and T1 cutting tools.
