Universal Screw
Powder non - high - speed steel and powder stainless steel, is a high - grade die steel. By means of powder metallurgy (atomized powder is treated with isostatic pressure under hot state)HIP, the dense billet with uniform microstructure and fine grain has higher toughness than the fusing cast high speed steel. Wear and corrosion resistance. The surface finish can reach Ra0.2 or above. Suitable for most injection molding conditions, and foreign high-end screw comparable!
