Basic knowledge about NM450 steel grade

The NM450 steel grade atmospheric corrosion resistance of high weather resistant structural steel is better than that of welding structural weathering steel, and is mainly used for bolt connection, riveting and welding structural parts for vehicles, containers, buildings, towers and other structures. But the welding performance of welding structural weathering steel is better than that of high weather resistant structural steel, and the welding structural weathering steel is mainly used for welding structural parts for bridges, buildings and other structures.

The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy NM450 steel grade are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of NM450 steel grade welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
