    What are the features for powder metallurgy? Using powder metallurgy method produce dense blanks, then through forging, rolling, and so on thermal deformation to get high speed steel profiles, hereinafter referred to as powder high speed steel. Powder high speed steel has uniform structure, fine grain, eliminates high speed steel segregation. Thus powder metallurgy has higher toughness and wear resistance than same fused cast high speed steel. At the same time, it also has properties of small deformation after heat treatment, good forged grinding performance. Carbide content of powder high speed steel greatly exceed allowed range of casting high speed. Improving hardness to HRC67 at least, so as to further improve the wear resistance.
