As a new type of coil material, compared with the traditional steel coil, differences between a573 gr.70 and a515 gr.70 steel, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the differences between a573 gr.70 and a515 gr.70 steel steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the differences between a573 gr.70 and a515 gr.70 steel weathering steel is purified and the content of inclusions is greatly reduced.
