The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of Q235NH weathering bridge steel coil, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.

Most common Q235NH weathering bridge steel coil steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled Q235NH weathering bridge steel coil steel plates.
