Q355NH material has a protective rust layer that resists atmospheric corrosion and can be used to manufacture low-alloy structural steels for steel structures such as vehicles, bridges, towers, containers, etc. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.

Different form en 10025-6 S690QL equivalent ASTM, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for en 10025-6 S690QL equivalent ASTM pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common en 10025-6 S690QL equivalent ASTM carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The en 10025-6 S690QL equivalent ASTM, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
