The company adopts the ASTM A588 heavy plate 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 ASTM A588 heavy plate management system, and has realized the comprehensive integration of the three systems.
Vanadium is a weak deoxidizer. Adding vanadium into ASTM A588 heavy plate 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.
Features of Q235NHA sheet:Q235NH steel sheet has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, and labor and energy saving. It has a long service life when used in harsh environments. It has a protective rust layer to resist atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere.
The "Plan" pointed out that by the end of December 2020, the steel production capacity in Tianjin will be controlled at about 15 million tons, and the steel production capacity in Hebei Province will be controlled within 200 million tons, and the elimination of the carbonization chamber with long furnace age and poor furnace condition will be accelerated. 4.3 Rice coke ovens promote the gradual withdrawal of independent coking companies. At present, there are 24 steel enterprises in Shanxi Province in need of transformation, of which 17 have been completed, and the remaining 7 enterprises are speeding up project-related finishing work.
