Since its establishment, the company has adhered to the business philosophy of "integrity management, reputation first, mutual benefit", and adheres to the training principles of integrity, innovation and pioneering for its employees. It has long been dedicated to BS700MC high strength alloy steel steel structure, shipbuilding, boiler vessel manufacturing, machinery manufacturing.

Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, BS700MC high strength alloy steel are strict. In the chemical composition of boiler steel, BS700MC high strength alloy steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
