NM400 material meaning HIC Tested Boiler Steel Plates

The NM400 material meaning modulus of elasticity is used to calculate when a piece of steel will deform too much to bear a load safely. Other properties of A36 steel plate include NM400 material meaning yield strength, or the maximum stress of steel before permanent deformation.

Oxygen (O) is a harmful element in steel such as NM400 material meaning. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

Laser cutting NM400 material meaning has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the NM400 material meaning cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

Both parties shall confirm the NM400 material meaning material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NM400 material meaning steel plant.
