American Standard A588 Weathering Steel Manufacturer for Railway Bridges

The production process of A588 weathering steel plate: Weathering steel is usually smelted in a furnace with fine materials (converter, electric furnace, microalloying treatment, argon LF refining, low superheat continuous casting controlled rolling and cooling).

During smelting, scrap steel is added to the furnace together with the charge and smelted according to conventional methods. After unloading, add deoxidizers and alloys. Immediately after the molten steel was treated by argon blowing, the molten steel was cast, and the molten steel after argon temperature adjustment was cast by a continuous casting machine. As a slab, due to the addition of rare elements to the steel, the weathering steel can be purified and the content of inclusions is greatly reduced.

A588 weathering steel is widely used in outdoor steel such as vessels, power plant chimneys and railway works such as large outdoor sculpture steel. A588 weathering steel (i.e., atmospheric corrosion resistant steel) is inexpensive between ordinary steel and stainless steel. The alloy steel series is one of the most advanced steel series in the world's super steel technology field after being integrated into the new mechanism, new technology and new process of modern metallurgy.

Chemical composition of A588 weathering steel
C:≤0.19 Si:0.3~0.65 Mn:0.8~1.25 P:≤0.03 S:≤0.03 Ni:≤0.4 Cr:0.4~0.65 Cu:0.25~0.4 V:0.02~0.1

A588 weathering steel plate forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., and has high atmospheric corrosion resistance. It can be used to manufacture workshops, general buildings and various construction machinery, such as Drilling rigs, electric shovels, mining vehicles, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts used in various engineering and mine construction.
