How to identify shoddy nm400 steel tensile strength
The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with NM400 steel tensile strength good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.
The advantages of NM400 steel tensile strength, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.
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.
For wear-resistant steel plate, it is not the higher the hardness, the better the wear resistance! Hardness is the basis of excellent wear resistance of NM400 steel tensile strength, wear-resistant steel plate, but the relationship between hardness and wear resistance is not in direct proportion. The reason why wear-resistant steel plates are wear-resistant is that they have hard particles and soft matrix. Generally, in the process of wear, there will be some falling substances, which will be incorporated into the soft matrix and will not cause great damage to the surface.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. NM400 steel tensile strength, 20CrMo steel pipe is generally used in quenching and tempering state.
