What is the notice of preheating before nm400 steel grade cutting

The alloy wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbide in the metallographic structure is fibrous, and the fiber direction is perpendicular to the surface; alloy carbide It has strong stability at high temperature, maintains high hardness, and also has very good anti-oxidation performance. NM400 steel grade, wear-resistant steel plate can be used normally within 500 ℃.

The main raw material of NM400 steel grade, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
