How to judge the authenticity of NM400 wear plate

NM400 wear plate is a special steel plate for construction machinery. It has strong hardness and toughness, which can resist a large range of external impact and ensure production safety. However, there will be a phenomenon of replacing it with similar raw materials on the market, which will lead to a decrease in the quality of machinery and safety cannot be guaranteed. But we can still judge by some means.

First check the element composition of the steel plate. Professional instruments can be used to detect the proportion of various elements in the material, such as the main elements carbon, silicon, manganese, phosphorus, etc., such as manganese, which contains 1.6% in NM400 wear plate. It is higher than ordinary steel. This is because the role of manganese in steel is to increase hardness and wear resistance. The higher its composition, the stronger the performance of the steel.

In addition, when there is no instrument around, you can use observation to preliminarily judge the authenticity of the NM400 wear plate. The real NM400 wear plate is pinkish, which is the main color of iron.
