Flaw detection of p265gh steel tube

Under normal exposure to the atmosphere, P265GH steel tube, bare steel forms a tight protective oxide film during the first few months of atmospheric corrosion. Sometimes architects choose bare steel structures because they want to get the appearance of uniform atmospheric oxidation on the steel surface, and sometimes they are to save the protective coating for economic purposes. To use these low-alloy high-strength steels in a bare state, the design must consider that the surface of the steel cannot be wet for a long time, and special attention should be paid to the special atmospheric environment to ensure that the corrosion rate of the steel is allowed under this condition.

The company mainly supplies p265gh steel tube steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of p265gh steel tube steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

With our own engineers, metallurgists and CAD draftsmen, we can provide total support from design through to machined casting. OEM precision casting investment p265gh steel tube casting auto parts, customized investment casting auto parts, custom precision casting automobile parts, truck casting iron fitting parts.Precision Casting: Tooling making → Wax pattern → Shall making → Chemical analysis → Pouring → Measurement & inspection → Heat Treatment → Processing → Finished product.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of p265gh steel tube 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 p265gh steel tube steel, can be used as an alloying element of low alloy steel.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
