The wear-resistant layer of NM450 plate impact resistance wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy NM450 plate impact resistance carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the NM450 plate impact resistance steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of NM450 plate impact resistance seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For NM450 plate impact resistance ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the NM450 plate impact resistance standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
