BBN supply nm400 steel specifications plasticity
As the tungsten content increases, the strength and toughness of the NM360 wear-resistant steel plate increase. When the mass fraction of tungsten exceeds 1.06%, the toughness decreases due to the increase in the amount of carbide precipitation. This is because tungsten combines with carbon atoms in the NM360 wear-resistant plate to form a short-range ordered C-w atom pair bond structure. The C-w atomic bond is stronger than the C-Mn and C-Fe atomic bonds. Therefore, after adding tungsten to the NM360 wear-resistant steel plate, cracks will be formed, and the energy required to break the atomic bond will be greatly increased. The toughness and strength of NM400 steel specifications, NM360 wear-resistant steel plate treated with water toughening treatment will also be significantly improved.
The addition of Ca element in steel such as NM400 steel specifications can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
Medium and thick plates NM400 steel specifications are mostly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates can also be used to make all kinds of containers, furnace shells, furnace plates, automobile static steel plates and so on. Among them, shipbuilding steel plate is used to make marine and inland ships. The shipbuilding steel plate NM400 steel specifications is required to have high strength, plasticity, toughness, good cold bending performance, welding performance and corrosion resistance.
We have a large number of NM400 steel specifications steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the NM400 steel specifications required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.
