The boiler steel plate is used to manufacture various boilers and important accessories. Because the A573Gr.70 steel for bolted and welded structures boiler steel plate works under the medium temperature (below 350 ° C) and high pressure state, it is not only subject to high pressure, but also to impact, fatigue load and water and air corrosion. The boiler steel plate is required to ensure certain strength and good welding and cold bending performance.Bridge steel plate A573Gr.70 steel for bolted and welded structures is used for large railway bridge. The bridge steel plate is required to bear dynamic load, impact, vibration, corrosion resistance, etc.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

A573Gr.70 steel for bolted and welded structures, Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.
