The A633 Gr C grade steel mill test certificate

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 A633 Gr C grade steel 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 A633 Gr C grade steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
