P355GH steel welding process, SA533 GrB CL2 steel plate is an American Standard vessel steel plate, which is in accordance with ASME SA533 / SA533M. And it is quenched and tempered Mn-Mo and Mn-Mo-Ni alloy steel plate.The chemical composition of SA533 GrB CL2 steel plate is C: 0.25, Mn: 1.15-1.50, Mo: 0.45-0.60, Ni: 0.40-0.70, Si: 0.15-0.40, P: 0.012, S: 0.015, Cu: 0.10, V: 0.01.
The company's quality is first, the price is reasonable, the construction period is guaranteed, and the purpose of abiding by the contract, our steel p355gh steel welding process products have received high recognition from customers from the world. The company adheres to the operating principles of equality and mutual benefit and abides by the contract. We sincerely welcome you to visit us, negotiate business cooperation, enhance friendship, develop and expand trade.
Composition characteristics of p355gh steel welding process product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%. 2) Add manganese-based alloying elements. 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in p355gh steel welding process etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
