nm400 wear-resistant plate and 65mn which wear-resistant? Wear plate manufacturers tell you

nm400 wear-resistant plate and 65mn which wear-resistant? Wear plate manufacturers tell you to say wear or nm400 wear plate is better. The chemical composition of the wear-resistant layer of the product has a carbon content of 4 to 5% and a chromium content of 25 to 30%. The volume fraction of the Cr7C3 carbide in the metallographic structure reaches over 50%, the macroscopic hardness is 56 to 62 and the chromium carbide The hardness of HV1400 ~ 1800. Due to the perpendicular distribution of carbides in the direction of wear, the wear resistance can be more than doubled even with cast alloys of the same composition and hardness. Compared with the wear resistance of several typical materials, it is as follows: (1) with low carbon steel; 20-25: 1 (2) with cast high chromium cast iron; 1.5-2.5: 1 NM400 wear plate is high strength wear resistant steel , Which has a high abrasion resistance, Brinell hardness of 400 (HBW) mainly in the need to wear occasions or parts to provide protection to make the device longer life expectancy, maintenance maintenance and reduce maintenance and downtime, a corresponding reduction Capital investment. Wear-resistant steel with high wear resistance and better impact performance, capable of cutting, bending, welding, etc., can take welding, plug welding, bolting and other means to connect with other structures in the maintenance process with the time-saving , Convenient and so on. It is widely used in industries such as metallurgy, coal, cement, electric power, glass, mine, building material, brick and tile etc. Compared with other materials, it has high cost performance and is favored by more and more trades and manufacturers. .
