Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled a572 grade 50 astm carbon steel grade yield products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the a572 grade 50 astm carbon steel grade yield rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
Q235 is a kind of carbon steel. a572 grade 50 astm carbon steel grade yield, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.
The company attaches great importance to systematic management, and has passed the a572 grade 50 astm carbon steel grade yield ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on a572 grade 50 astm carbon steel grade yield quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, a572 grade 50 astm carbon steel grade yield flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.
