In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This Q390D carbon steel plate sheet production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate Q390D carbon steel plate sheet size.

Between alloy wear-resistant layer and the substrate of wear-resistant steel is metallurgically bonded. Through special equipment and automatic welding process, high-hardness self-shielding alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different alloy shrinkage ratio, uniform transverse cracks occur. It is a distinctive feature of wear-resistant steel plates, Q390D carbon steel plate sheet.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel Q390D carbon steel plate sheet plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
