The company specializes in the research and development, production and sales of SPA-C steel for railway rolling stock 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 SPA-C steel for railway rolling stock five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,SPA-C steel for railway rolling stock rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
Pipeline steel plate API 5L Gr.B, SPA-C steel for railway rolling stock, X42, X46, X52, X56, X60, X65, X70, X80 is a key steel material for manufacturing straight-seam submerged arc welded pipe for high-pressure long-distance natural gas pipeline. X80 pipeline steel is currently the highest-grade pipeline steel in engineering application in the world. The our company produced X80 pipeline steel plates are successfully used in natural gas pipeline project with the largest wall thickness and diameter.
Corrosion resistant steel prices are generally higher. What are the applications of SPA-C steel for railway rolling stock, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.
Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in SPA-C steel for railway rolling stock steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of SPA-C steel for railway rolling stock steel.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. SPA-C steel for railway rolling stock, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
We are engaged in SPA-C steel for railway rolling stock corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, SPA-C steel for railway rolling stock ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
