ASME SA 53 seamless pipe is manufactured according to QStE340TM automobile frame steel coil ASME code. Because it belongs to low carbon steel, the surface hardness can only be improved by carburizing. If you are interested in BBN QStE340TM automobile frame steel coil ASTM A53 or ASME SA 53 carbon seamless pipe, please contact us for the latest price.
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet QStE340TM automobile frame steel coil is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
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 QStE340TM automobile frame steel coil 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 QStE340TM automobile frame steel coil weathering steel is purified and the content of inclusions is greatly reduced.
Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries.
