xar 400 steel plate VS A36 material
In today's xar 400 steel plate steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of xar 400 steel plate market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
Application range of NM400 wear plate, xar 400 steel plate:1) NM400 wear-resistant plate is used for metallurgical machinery equipment: iron ore sintering conveying elbow, iron ore sintering machine liner, scraper liner.2) NM400 wear-resistant plate is used for mining machinery equipment: mineral, stone crusher linings, blades.3) NM400 wear-resistant plate is used for other mechanical equipment: sand mill cylinder, blade, various port machinery wear-resistant parts.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as xar 400 steel plate, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
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.
