What are the uses of Q235NH steel structure

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has Q235NH steel structure strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and Q235NH steel structure pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the Q235NH steel structure, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.

The weldability of Q235NH steel structure is good. It means that under certain process and construction conditions, Q235NH steel structure can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

After adding a small amount of niobium, vanadium and titanium to Q235NH steel structure 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.

Q235NH steel structure, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.
