The gas cylinder steel coil and sheets are our main products. Our main conducted standards for gas cylinder steel coil and sheets are JIS G3116, GB6653, EN10120. The typical gas cylinder steel grades are SG255, SG295, SG325, HP265, HP295, HP325, P245NB, P265NB, P310NB, P355NB, etc. For the gas cylinder steel coil StE380 steel plate, we provide slitting, cutting, and stamping service. So as to meet different size and shape requirements of the customers. The gas cylinder steel coil and sheets are mainly used to make gas cylinders.The company specializes in the research and development, production and sales of StE380 steel plate 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 StE380 steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,StE380 steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.As the thickness and hardness of StE380 steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the StE380 steel plate from cutting cracks, preheating should be carried out before StE380 steel plate cutting. Special attention should be paid to preheating to make the entire StE380 steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole StE380 steel plate cannot be preheated, the partial preheating method can be used instead.Corrosion resistance mechanism of StE380 steel plate, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
