NM400 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.
