How to improve the quality of special shaped carbon steel plate NM450 cutting parts

Pageviews:

wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. wear resistant steel plate can be connected with other structures by welding, plug welding, bolt connection, etc.. It is time-saving and convenient in the process of maintenance site. Wear resistant steel plate carbon steel plate NM450 is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers.

we also provide the carbon steel plate NM450 welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful carbon steel plate NM450 welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for carbon steel plate NM450 iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.

carbon steel plate NM450 surface cracks refer to the linear cracks on the surface of carbon steel plate NM450, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: carbon steel plate NM450 surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
