NM 400

NM400 is a high-strength wear-resistant steel plate. It has quite high mechanical strength, and its mechanical properties are 3 to 5 times that of ordinary low alloy steel plate, which can significantly improve the wear resistance of mechanical related parts. Therefore, improving the service life of the machine can reduce the production cost. The superior resistance of NM400 allows significant savings in all the heavy applications where longer lifespan, lower weights, energy efficency and good weldability are of essence. The surface hardness of the product usually reaches 360~450HB. Suitable structural steel plate for processing and manufacturing wear-resistant and vulnerable parts of mines and various construction machinery.

  • NM400

400HB is a wear resistant steel with a hardness of 400 HBW, joined by high strength and excellent impact toughness. The superior resistance of NM 400 allows significant savings in all the heavy applications where longer lifespan, lower weights, energy efficency and good weldability are of essence. All plates in NM400 are:

- fully killed and fine-grain treated

- trimmed on all four edges,

- shotblasted,

- primerized

- UT tested according to EN10160 S1E1
