The company can provide the dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, markings and quality certificates of high-quality carbon structural steel hot-rolled steel plates and strips. Carbon and alloy steel grades 15Cr, 20Cr, A709 grade 50 structural steel sheet, 30Cr, 35Cr, 40Cr, 45Cr, 50Cr, 38CrSi, 12CrMo, 15CrMo, 20CrMo, 25CrMo, 30CrMo, 35CrMo, 42CrMo, 50CrMo, 12CrMoV, 35CrMoV, 12Cr1MoV, 25Cr2Mo1V, 38CrMoA1, 40CrV, 50CrV , 15CrMn, 20CrMn.
The company has allocated special environmental protection facilities for all A709 grade 50 structural steel sheet pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, A709 grade 50 structural steel sheet steel mill scale, environmental protection dust has reached 100%.
Try to use A709 grade 50 structural steel sheet high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A709 grade 50 structural steel sheet temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A709 grade 50 structural steel sheet nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A709 grade 50 structural steel sheet steel, can be used as an alloying element of low alloy steel.
The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel A709 grade 50 structural steel sheet plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
