high quality NM450 wear-resistant steel
nm450 is a common alloy wear-resistant material, which is formed after heat treatment.
Now the more advanced wear-resistant steel plate technology is generally the use of low-alloy materials, after a variety of special heat treatment technology processing and manufacturing, such as JFE-C450, DILLIDUR 450V, etc.
NM450, NM means wear resistance, 450 means the average Brinell hardness is about 450. NM450 is widely used in metallurgical industry, road construction industry, sand mill barrel, blade, U-shaped dump truck, various freight yard, dock mechanical parts, bearing structure, railway wheel structure, roll and so on.
