Comparison chart of S690QL high strength steel plates structural

Weathering steel for welding structure is added a small amount of alloy elements to the steel, such as steel, chromium, nickel, molybdenum, niobium, titanium, zirconium and vanadium, to form a protective layer on the surface of the metal substrate. Therefore, this improve the corrosion resistance and has good welding performance. Weathering steel for welding structure is mainly used in bridges, buildings and other structures. Our company can supply weathering steel plate, sheet, strip and sections, S690QL high strength steel plates with various shapes.

Will S690QL high strength steel plates, stainless steel rust? Under normal conditions, stainless steel will not rust. It has a great relationship to the composition of stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon and so on elements. Scientists have found that the more uniform the internal structure of steel, the closer the various components are linked, and the more difficult it is for corrosive substances to invade. In addition, a layer of oxide protective film is attached to the surface of stainless steel, which is just like wearing armor on steel, it is not easy to rust.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the S690QL high strength steel plates steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the S690QL high strength steel plates steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our S690QL high strength steel plates service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's S690QL high strength steel plates customer service to establish a good, comprehensive, full service system.
