镍铬耐磨铸铁

The hardness of HSS roll was over 66 HRC, the depth of hardened layer excesses 30 mm, the variation of hardness in the roll surface was smaller than 1.5 HRC, and the wear resistance of HSS roll was better than that of high chromium cast iron roll and high nickel chromium indefinite hilled cast iron roll, close to that of powder metallurgy hard alloy roll.

研制出的高速钢轧辊硬度超过66HRC，淬硬层深度超过30mm，辊面硬度差小于1.5HRC，耐磨性优于高铬铸铁和高镍铬无限冷硬铸铁轧辊，接近硬质合金轧辊。

Cr15Mo3 is chromium wear-resistant white cast iron, heat treatment of the microstructure of martensite matrix of chromium carbide + Paralympic +, macro-hardness of HRC 60 or more wear resistance than Ni-Hard Cast Iron It is a very good wear-resistant material that can be produced coal mill, ore crusher, cement mill, shot blasting machines, mud pump, slurry pumps and other wear and tear serious casting.

Cr15Mo3 是铬系耐磨白口铸铁，热处理后的金相组织为马氏体基体+铬的碳化物+残奥，宏观硬度HRC在60以上，耐磨性能优于镍硬铸铁，是非常好的耐磨材料，可制作磨煤机、矿石破碎机、水泥磨机、抛丸机、泥浆泵、渣浆泵等磨损严重的铸件。
