S690QL alloy steel plate for welded steel pipe

The company has a solid economic foundation, a strong network of relationships, complete technology and staffing. With my country’s entry into the WTO, the import and export trade is increasing day by day. In order to further meet the needs of S690QL alloy steel plate traders and importers and exporters, our company carefully builds for merchants One-stop service from door to door. We have a complete import and export service system in Mainland China, and S690QL alloy steel plate have established close cooperative relations with many shipping companies and airlines.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, S690QL alloy steel plate included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

In recent years, steel structure engineering has been developing to large-scale, lightweight and high parameter, such as large-span bridges, large hydropower stations, heavy engineering machinery, etc. This requires that S690QL alloy steel plate, structural steel has higher strength, better toughness, plasticity and welding properties, and Q690CF steel plate greatly meets these conditions. Q690CF steel plate is a kind of steel with bending strength higher than 690MPa and low welding crack sensitivity.

Due to the high cost support of raw material end and the re attack of environmental protection and production restriction of steel enterprises, the market supply is limited and S690QL alloy steel plate traders are willing to support the price. However, the influence of off-season continues, the terminal demand is greatly reduced, and the downstream merchants mainly purchase on rigid demand. The overall delivery performance is not good. It is expected that the S690QL alloy steel plate price will be adjusted steadily tomorrow.
