High quality nm400 equivalent material manufacturer in China

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as NM400 equivalent material. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

The effect of elements in the wear plate on high temperature temper brittleness: chromium, manganese, nickel, silicon, etc. play a role in promoting, while molybdenum, tungsten, titanium, etc. play a retarding role, and carbon also plays a role in promoting. Generally, NM400 equivalent material, carbon wear-resistant steel plates are not sensitive to high temperature tempering brittleness, while binary or multi-element alloy steels containing chromium, manganese, nickel, and silicon are very sensitive. The degree of sensitivity varies depending on the type and content of alloy elements.

The difference between NM400 equivalent material, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

Recently, the epidemic situation in developed countries such as Europe and the United States has become more and more serious, leading to the stagnation of economic activities in some countries, which has also affected domestic and foreign trade orders. In particular, industries such as steel, which have a long industrial chain and a wide range of industries, are more seriously affected. The development of foreign epidemic situation has different influence on the direct and indirect export of NM400 equivalent material and so on steel products.
