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 A709 Gr 50 low alloy steel sheet 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 A709 Gr 50 low alloy steel sheet rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with A709 Gr 50 low alloy steel sheet, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
