NM400 is an abrasion resistant plate with a hardness of 400 HBW, which has a very high mechanical strength, the mechanical properties of ordinary low-alloy steel plate of 3 to 5 times; can significantly increase the wear resistance of mechanical related components; therefore improve the mechanical life; Reduce the production cost of the product surface hardness is usually reached 360 ~ 450HB. Used for mining and construction machinery processing and manufacturing, and other wear-resistant wearing parts applicable structural steel.

Rolling range: Thickness*Width*Length 3-100mm*1220-4200mm*5000-18000mm
Supplementary Technology: Brinell hardness, HBW according to EN ISO 6506-1, on a milled surface 0,5–2 mm below plate surface per heat and 40 tons. Tests are made for every variation of 15 mm in the thickness of plates from the same heat.
Main application:With high speed development of technology and modern industry,manufactures are more likely to use high strength abrasion resistance steel plates so as to reduce the economic lost brought by part wear.
Tolerance standard for dimension:GB/T709
Test: Low temperature impacting test,Ultrasonic examination,Normalized,Quenched and tempered,Tempered,TMCP and Tempered.
