Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between Q310GNH hot rolled steel angles, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
Corrosion resistant steel is a kind of stainless steel, which can resist corrosion in some strong corrosive media. Stainless steel can only resist corrosion in air or weak medium. Stainless steel is not necessarily corrosion resistant, corrosion-resistant steel must be stainless steel. Corrosion resistant steel is durable and can be stored outdoors for a long time without being damaged in bad weather. Corrosion resistant steel is not easy to rust, but it is not absolutely rust free. The strength, precision and toughness of Q310GNH hot rolled steel angles, corrosion resistant steel are very good, and can be the processed and used for many purposes.
Q310GNH hot rolled steel angles, Hot-rolled steel coils are made of steel billets, which are made into strip steel by the rough rolling mill and the finishing mill after heating. The hr steel strip from the rolling mill behind the finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel coil by the coiler. The cooled steel coil will undergo different processes according to the different needs of users, and is processed into steel plates, flat coils and slit steel strip products.
