What is requirement for surface of S275NL carbon steel material

S275NL carbon steel material,,S275NL carbon steel material., European standard high strength EN10025-6 S690QL steel plates are mainly used for manufacturing construction machinery, mining machinery, all kinds of engineering machinery, such as the drilling rig, the electric shovel, the electric wheel dump, the mine motor, the excavator, and the loader for all kinds of engineering construction., etc.The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.S275NL carbon steel material,As alloy 400 is a kind of metal with good corrosion resistance, it shows good uniform corrosion resistance in the marine atmosphere. This is because alloy 400 can form a very thin and tough protective film. Uniform corrosion is one of the easiest forms of corrosion to deal with, because engineers can quantitatively determine the corrosion rate of metals and accurately predict the service life of metals.S275NL carbon steel material,The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel plates It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system BBN company provides customers with solutions at low prices, high quality, and fast response service,S275NL carbon steel material.
