GB/T709 NM400 abrasion resistant steel plate

NM400 is one kind of Chinese wear/abrasion resistant steel plates, which is well received in Middle East and Africa.

An NM400 wear-resistant steel was hot rolled and then the plates were heat-treated by direct quenching and tempering and reheat quenching and tempering techniques, respectively.

Mechanical Property of NM400 steel:

Tensile strength (≥Mpa)	-20℃ impacting test absorbed energy (Longi.J)	Elongation in ≥,%	HBW
1200	≥24	50mm	370-430
		10

GB/T709 NM400 steel Main application:
With high speed development of technology and modern industry, manufactures are more likely to use NM400 abrasion resistant steel plate so as to reduce the economic lost brought by part wear.
