The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality A514 grade P alloy steel plate products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.
In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials A514 grade P alloy steel plate used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, A514 grade P alloy steel plate. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system.
