The company adopts the P295GH steel pressure vessel international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety p295gh steel pressure vessel management system, and has realized the comprehensive integration of the three systems.

Vanadium is a weak deoxidizer. Adding vanadium into p295gh steel pressure vessel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

Just as p295gh steel pressure vessel, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.

In the first quarter, p295gh steel pressure vessel, crude steel output in Asia amounted to 315.15 million mt, falling by 0.3 percent, with 234.45 million mt produced by China, up 1.2 percent, 24.36 million mt produced by Japan, decreasing by 2.4 percent, 27.5 million mt produced by India, falling by 5.3 percent, and 16.94 million mt produced by South Korea, down by 4.8 percent - with all comparisons on year-on-year basis.
