Wear resistant materials mainly include high manganese steel series, wear-resistant chromium cast iron series, wear-resistant alloy steel series, ADI series, composite or gradient materials and hard alloy material series, non-metallic wear-resistant material series.

High manganese steel series

A typical example is high manganese steel ZGMn13. Externally hard and internally strong, both wear-resistant and impact resistant. In addition, the heavier the impact surface, the more complete the surface hardening, and the better the wear resistance.

Wear resistant chromium cast iron series

Chromium cast iron can be divided into three categories according to its structure and purpose. The first type is chromium white cast iron with excellent high-temperature performance. This type of cast iron contains 33% chromium, and its structure is mainly composed of austenite and iron chromium carbides, with the possible presence of ferrite.

Wear resistant alloy steel series

Divided into low-alloy steel, medium alloy steel, and high alloy steel. Wear resistant alloy steel can achieve the required material impact toughness and hardness indicators by adjusting its chemical composition and heat treatment process. Hardness can reach HRC=52-58, toughness can reach ak=15-30J/cm2

The rotating frame produced by the factory meets the quality of OEM factory parts. The selection of raw materials before production, strict size control during the production process, and inspection and testing after production are all processes aimed at obtaining a more durable and reassuring product  195-30-66550
