The market price forecast of Q690D steel material

Q370qC, Q370qD, Q690D steel material and Q370qE are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. Used for the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges).

We have many kinds of boiler and pressure vessel steel materials, including ASTM, ASME, DIN, JIS, en, GB and other multinational standards, dozens of steel grades. Customers have a wide range of options. At the same time, we have obvious advantages in wide and thick plates. The widest boiler plate can be more than 5 meters. The Q690D steel material and pressure vessel steel price is also competitive, and there is a professional team to serve you.

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 Q690D steel material 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 Q690D steel material 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.
