carbon content of NM400 equivalent ASTM material

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length carbon content of NM400 is suitable for the length required by the construction of steel pipes.

According to the different heating and melting methods of wear-resistant steel plate, carbon content of NM400, 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.

Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry.
