After adding a small amount of niobium, vanadium and titanium to P295GH steel elements etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.

ASTM A387 steel is the standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. Plates under this standard Hebei Metals supplies include ASTM A387 Grades 2, p295gh steel elements Grade 12, Grade 11, Grade 22, Grade 22L, Grade 21, Grade 21L, Grade 5, Grade 9, Grade 91. Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels. These Cr-Mo A387 alloy steel is primarily manufactured for welded boilers and pressure vessels for elevated temperature service.

The company formulates appropriate p295gh steel elements product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of p295gh steel elements welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
