POWDER STAINLESS STEEL GRADE A
Powder high speed steel and powder stainless steel arethe world's top tool steel. The powder metallurgy method(atomized powder is subjected to isostatic pressing in ahot state)HIP produces a dense billet with uniform structure and fine grains, which has higher toughness,wear resistance and corrosion resistance than cast high-speed steel. The surface finish can reach above Ra0.2.Suitable for the vast majority of injection molding conditions, comparable to foreign high-end screws!
Powder Stainless Steel Grade A Chemical Composition
Chemical composition(%)：
Corresponding plastic raw materials
PA, PC, LCP, PBT, PPS, PEEK, PPSU, etc. add more than 35% glass fiber, carbon fber + Vo fireproof grade, as well as magnetic powder, iron powder, ceramic injection.
Features
Excellent wear resistance and good corrosion resistance;
High strength, can withstand the requirements of high torque, high rotation speed andhigh firing rate;
The cost is high, and it is suitable for the manufacture of high wear-resistant andcorrosion-resistant screw groups.
Application industry
Precision molding for optics, home appliances, medical, connectors, MIM, ceramic injection molding, etc.
