The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy P355GH used for gas industry products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of p355gh used for gas industry stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

The aging treatment of p355gh used for gas industry steel plate: in order to eliminate the size and shape changes of precision measuring tools or molds and parts in long-term use, the workpiece is often reheated to 100℃ -150 ℃ and maintained for 5-20 hours before finishing at low temperature after tempering. This p355gh used for gas industry process is called aging to stabilize the quality of precision parts.It is particularly important to aging steel members under low temperature or dynamic loading conditions to eliminate residual stress and stabilize steel structure and size.

p355gh used for gas industry, P275 P355 P420 P460 boiler steel plate application equipment: reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, boiler drum, liquefied petroleum gas cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components. p355gh used for gas industry can meet the requirements of flaw detection, Z15-Z35 thickness direction performance and high strength and toughness.

As soon as the grains of the steel sheet become coarse, the forming limit decreases. The total elongation, n value and r value in the mechanical properties of the p355gh used for gas industry steel plate have no direct influence on the forming limit of spinning. The steel plate used in the test is very thin (about 0.5mm), and the commonly used thickness p355gh used for gas industry steel plate (0.8-1.6mm) will definitely be much higher than the above limit.
