What are the benefits of powder high speed over conventional high speed?

Powder high-speed steel could obtain sufficient hardness through the TRD process with no post hardening. Materials without the cobalt should get about 61-62 HRC and material with cobalt should get about 67-69 HRC, thus they can eliminate the disadvantage of high speed steel accompanied with material cost increase.
