Chromium Steel Casting Foundry

Qiming Machinery is a chromium steel casting foundry, which has been crushing the market for decades. High chromium Steel Is a good performance and special attention to the anti-wear materials. It is much higher than the alloy steel wear resistance, and much higher than the general white cast iron toughness, strength, while it also has good resistance to high temperature and corrosion resistance, combined with convenient production, cost is moderate, and was Known as the contemporary one of the best anti-abrasive wear materials.
