Supply xar 400 steel plate 6cm steel customized

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the xar 400 steel plate plate should be derusted before cutting.

The shape defects of wear-resistant plates, xar 400 steel plate mainly refer to various waves and buckles existing in continuous rolling mill products. The main reasons are the unbalanced load distribution of the racks, poor tension settings between racks, and unreasonable work roll profiles. This kind of defect is easy to cause the adhesion phenomenon in the hood retreat, which has a great impact on the wear-resistant plates product quality. Edge defects are mainly caused by poor pickling trimming quality or poor plasticity of strip steel.

The difference between xar 400 steel plate, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

In 2010, the 87th session of the International Maritime Organization (IMO) Maritime Committee passed the "Performance Standards for Alternative Anticorrosion Measures for Crude Oil Cargo Tanks". It is mandatory that the cargo tanks of large oil tankers above 5,000 dwt need to be protected or used The construction of corrosion-resistant steel promotes the rapid development of the research and application of corrosion-resistant steel for oil tankers in China. At present, the performance of domestic corrosion-resistant steel has reached the world's leading level and can meet the requirements of large-scale applications.
