NM400 Steel Plate
steel Product Introduction
NM400 is a high strength wear-resistant steel plate. NM400 has quite high mechanical strength; Its mechanical properties are 3 to 5 times that of ordinary low-alloy steel plates; It can significantly improve the wear resistance of mechanical parts. Therefore, improve the service life of the machine; Reduce production costs. The surface hardness of the product usually reaches 360 ~ 450HB. Used in mining and various construction machinery for wear-resistant parts processing and manufacturing and other suitable structural steel plate.
Impact resistance: The impact resistance of the wear-resistant plate is very good. During the process of conveying materials, even if there is something drop from high place, it will not cause much damage to the wear-resistant plate like NM400.
Heat resistance: Generally, NM 400 wear resistant plates below 600 degrees can be used normally. If we add some vanadium and molybdenum when manufacturing wear-resistant plates, it is even no problem to use those abrasion resistant plate NM400 at high temperatures below 800 degrees.
Corrosion resistance: Because the NM400 wear-resistant steel plate contains a large amount of Cr, the corrosion resistance of the wear-resistant plate is excellent, and there is no need to worry about corrosion.
Cost-effectiveness: The price of NM 400 wear-resistant plates is usually 3 to 4 times higher that of ordinary steel plates, but the service life span of wear-resistant plates is more than 10 times longer than ordinary steel plates, so those NM400 wear resistant plate / sheet is very cost-effective.
Easy processing: The wear-resistant plate has very strong weldability, and it can also be easily bent into various shapes, making it very convenient to process.
