NM600 Abrasion Resistant Steel Plate

NM600 Abrasion Resistant Steel Plate

1, NM600 wear resistance

The chemical composition of the wear-resistant layer of the alloy carbon content of 4 ~ 5%, chromium content of 25 ~ 30%, the volume fraction of Cr7C3 carbide in the metallographic structure of the CR7C3 carbide reached more than 50%, the micro-hardness of HRC56 ~ 62, the hardness of chromium carbide HV1400 ~ 1800. Because the carbide is vertically dispersed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness. The wear resistance of several typical materials is compared as follows:

2, NM600 wear-resistant plate impact resistance:

The substrate of the wear-resistant composite steel plate is low carbon steel or low alloy. Stainless steel and other resistant materials, showing the superiority of bimetal, wear-resistant layer against the wear of the wear medium, the substrate bears the load of the medium, so it has outstanding impact resistance. Able to withstand impact and wear such as high drop hoppers in material handling systems.

3, NM600 steel plate chemical composition and better heat resistance:

Alloy wear-resistant layer recommendation is used under ≤600 working conditions. If vanadium, molybdenum and other alloys are involved in the alloy wear-resistant layer, the application temperature of recommendation can withstand ≤800 high temperature wear is as follows: General carbon steel substrate recommendation is not higher than 380 working conditions; Low alloy heat resistant steel plate (15CrMo, 12Cr1MOV, etc.) substrate recommendation is not higher than 540 working conditions; Heat-resistant stainless steel substrate is recommended for use in conditions not higher than 800.
