Wear resistance of NM600 wear-resistant steel plate

In the chemical composition of the alloy wear-resistant layer, the carbon content is 4~5%, and the chrome content is as high as 25~30%. The volume fraction of Cr7C3 carbide in its metallographic structure is more than 50%. The macro hardness of NM600 wear-resistant steel plate is HRC56~62 , The hardness of carbide is HV1400~1800.

Because the carbides are distributed perpendicular to the wear direction, the wear resistance is more than doubled even compared with the cast alloys of the same composition and hardness. I believe that many friends who do not know much about NM600 wear-resistant steel plate will have such questions.

The bi-metal clad wear-resistant steel plate is a plate product specially designed for large-area wear conditions. It is a common low-carbon steel with good toughness and plasticity, or a low-alloy steel surface with a certain thickness of high hardness and a certain thickness by surfacing method. NM600 wear-resistant steel plate made of wear-resistant layer with excellent wear resistance.

The wear-resistant layer of NM600 wear-resistant steel plate is mainly made of Ming alloy, and other alloy components such as manganese, aluminum, niobium, and nickel are also added. The carbides in the metallographic structure are distributed in fibers, and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach HV1700-2000 or more, the surface hardness of NM600 wear-resistant steel plate can reach HRc58-62, alloy carbide has strong stability at high temperature, adhere to high hardness, and also has good resistance Oxidation function, completely normal use within 500 ℃.
