NM400 steel plate

NM400 steel plates are demanded widely by many commercial industries as they offer great wear resistance, high strength and thus significantly improving wear resistance of heavy mechanical parts.

They are also known as wear–resistant plates. As compared to ordinary or low alloy steel mechanical properties of NM400 steel plate is 3 to 5 times more. Thus, the service life of this grade alloy helps to reduce the cost of production. The processing and manufacturing of the product of structural steel plate is done according to the suitability and necessity of the customers. Mostly this grade is brought into application in various manufacturing enterprises.

NM400 steel properties

Wear resistant steel plate refers to the special plate products used under large area wear condition. At present, the commonly used wear-resistant steel plates are made of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing welding with a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance. In addition, there are cast wear-resistant steel plates and alloy quenched wear-resistant steel plates.


The series of NM wear-resistant steel combined the properties including high strength, high hardness, high wear resistant, weldable, bendable and mainly applied in:

  • Edge of loaders in loader industry
  • Wear-resistant lining plate in crusher industry.
  • Slat type conveyer in colliery mechanical industry.
  • Lining plate of coal pulverizer in power industry.
  • Lining plate of hopper for heavy handling truck.
  • NM400 wear resistant plate ensures unbeatable performance, savings and enhanced lifetime for your equipment. Weather you are looking to loose weight or gain strength in applications such as truck bodies, dumper bodies, containers and buckets or if you need production wear parts that simply outlast other materials, NM400 is the best choice.
  • The outstanding performance characteristics of NM400 wear plate come from a combination of hardness, strength and toughness. As a result nm400 can stand up to sliding, impact and squeezing wear. Nm400 goes beyond wear resistance, allowing you to protect your equipment investment and work more effectively.
  • In truck bodies and containers, NM400 ensures a longer lifetime and highly predictable performance. Its high strength and hardness often allows for a thinner plate, enabling a higher payload and better fuel economy.
  • NM400 in your bucket translates to a longer equipment lifetime and enhanced reliability thanks to outstanding wear and deformation resistance. Enhanced performance is achieved because NM400’s wear resistant properties are evenly distributed across the plate.
