NM360 NM400 NM500 Wear Resistance Steel


NM is Chinese standard of wear resistance steel, N is the capital letter of Resistance, M is the capital letter of Wear.

 

NM360 NM400 NM500 has a very high mechanical strength; its mechanical properties are 3 times to 5 times that of ordinary low-alloy steel sheets; it significantly improves the wear resistance of machine-related parts; thus improving the service life of machines and reducing the production costs. Usually reach 360 ~ 550HB. For mining and various construction machinery wear and wearing parts processing and manufacturing, and other applicable structural steel.


NM400 is a kind of wear-resistant steel. NM- "wear" and "grind" words that wear-resistant use Hanyu Pinyin The first letter 400 is the Brinell hardness HB value. (400 hardness value is broad, domestic NM400 hardness range 360-420.)


Wear-resistant steel delivery status is divided into 


1: tempering status 

2: quenched state (quenched state = quenching + tempering)


NM360 NM400 NM500 wear-resistant steel widely used in construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product components. Excavators, Loaders, Dozers bulldozers, edge plates, side blades, blades. Crusher liner, leaves.
