S690QL plate stockists 300 Tons

Types of steel plates our company supply: A36 carbon structural steel plate, A572 low-alloy high-strength steel plate, S690QL plate stockists, steel plate for bridge, S355 steel plate for building structure, Grade AH36 steel plate for shipbuilding and offshore platform, steel plate for boiler and pressure vessel, mould steel plate, steel plate for alloy structure, API 5L Gr.B pipeline steel plate, high-strength high toughness steel plate, corrosion-resistant steel plate, composite steel plate, wear-resistant steel plate.

The company specializes in the research and development, production and sales of S690QL plate stockists seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has S690QL plate stockists five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,S690QL plate stockists rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the S690QL plate stockists steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of S690QL plate stockists seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel, S690QL plate stockists. The so-called low alloy means that the total amount of alloying elements in steel is less than 3%. High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloy elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the requirements of use and low cost.
