The basic phases of SPV355 vessel steel, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
With the experienced staff in the steel industry, BBN steel specializes in steel deep processing service. We provide access to best-in-class processing for steel plates, steel pipe and tubes, including laser cutting, saw cutting, bending, welding, drilling, grinding and more, to give our customers the products they need in exactly the way they need them
Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between SPV355 vessel steel, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge SPV355 vessel steel stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel. Welcome to contact us and consult steel price, our sales person will give you professional answers and suggestions.
