Nm400 Steel Plate Archives
However, the wear-resistant plates on the market are uneven, and there are mn plates instead of the phenomenon. The choice depends on the material list, and the factory label and logo on the plate. It is best to test the hardness.
Nm400 Steel Plate Archives
The main material of the wear-resistant plate is steel, the main component is low carbon steel plate and alloy wear-resistant layer, in which the alloy wear-resistant layer occupies 1/2~1/3 of the thickness of the whole plate, and the main chemical composition is chromium. Therefore, it can reach 20% to 30% of all material content, the surface hardness is very high, and the wear resistance is also very good, and the use of life is longer. The hardness of NM400 is required to be between 360 and 440.
