S690QL1 steel tubing made in China

At present, in the iron and steel manufacturing industry, there are more and more manufacturers of S690QL1 steel tubing, automobile steel plate, so it is very important for us to find a high-quality automobile steel plate manufacturer for cooperation. In the selection of S690QL1 steel tubing, automobile steel plate manufacturers and products, it is better to find several companies to compare, and to summarize and select a more suitable automobile steel plate manufacturer to cooperate. We sorted out a few ways to select high-quality S690QL1 steel tubing, automobile steel plate manufacturers, and hope to help you to purchase!

High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, S690QL1 steel tubing, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.

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 S690QL1 steel tubing 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 S690QL1 steel tubing 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.
