NM400 abrasion resistant steel plate and NM500 abrasion resistant steel plate are both widely used in machinery and parts of various industries. The differences between NM400 abrasion resistant steel plate and NM500 abrasion resistant steel plate are mainly reflected in the following aspects.
Different chemical composition. The chemical composition of NM400 abrasion resistant steel plate and NM500 abrasion resistant steel plate is mainly different in terms of C and Cr and other trace elements.

Different hardness ranges. Hardness, as an important indicator of abrasion resistant steel plate, has always been the first element for many people to choose abrasion resistant steel plates. The hardness range of NM400 abrasion resistant steel plate and NM500 abrasion resistant steel plate is quite different. The factory hardness of NM400 abrasion resistant steel plate is required to be between 370-430, and the factory hardness requirement of NM500 abrasion resistant steel plate is between 460-540. The harder the abrasion resistant steel plate is, the more wear-resistant it is, but the processing performance and toughness will also be worse, so you need to choose it as appropriate.
3. In terms of mechanical properties, NM400 abrasion resistant steel plate and NM500 abrasion resistant steel plate have great differences, such as yield strength, tensile strength, elongation, bending resistance and impact resistance. NM500 abrasion resistant steel plate is stronger in yield strength, tensile strength, and bending resistance, but the elongation and impact resistance will also be slightly reduced.
