Weathering steel a573 grade 58 carbon-manganese-silicon steel grade generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, the scrap steel is added to the furnace along with the charge and smelted according to the conventional process.
Our company's a573 grade 58 carbon-manganese-silicon steel grade power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the a573 grade 58 carbon-manganese-silicon steel grade utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
Processing performance of quenched and tempered steel: a573 grade 58 carbon-manganese-silicon steel grade plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, a573 grade 58 carbon-manganese-silicon steel grade.
The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel a573 grade 58 carbon-manganese-silicon steel grade 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.
