The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.
According to the different heating and melting methods of wear-resistant steel plate, NV F40 hull steel structural plate, wear-resistant steel plate also has its own melting welding method. Cast welding is an earlier welding method, which uses the heat released during the oxidation of thermite or magnesium thermite to melt metal: its characteristics are simple equipment and operation, but for wear-resistant steel plate, the welding quality is not high. It is only used to repair the workpiece.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous NV F40 hull steel structural plate pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
