Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used S690QL material equivalent, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of S690QL material equivalent, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
