Abstract

PURPOSE: To provide a high speed steel with high wear resistance and superior machinability by regulating the W equivalent (W+2Mo) of a steel contg. C, Cr, V, Co, W and Mo to a specific range in powder metallurgy.
CONSTITUTION: The high speed steel by powder metallurgy consists of C; 1.2W 2.2%, Cr; 3W5%, V; 4W6%, Co; 0.1W5.5%, W and Mo; W equivalent (W+ 2Mo); 16W24%, and the balance Fe. N≥0.2% may be added satisfying C+N= 1.4W2.4% to further enhance the machinability of the steel.
