High quality EN steel grade S235J0 material manufacturer in China

How to choose the material and specification of EN steel grade S235J0 material, boiler tube? First, select the specification according to the actual use. Secondly, material: the suitable boiler tube material is different for different use scenarios. Thirdly, the wall thickness of the boiler tube should be strictly in accordance with the relevant standards. If the thickness is not up to standard, it is easy to cause accidents, so it must be strictly controlled. Finally, the boiler tube should be checked in time when receiving the goods, and the relevant instruments should be used to detect whether the steel quality has reached the standard, if not, it can be rejected.

The company specializes in the research and development, production and sales of EN steel grade S235J0 material 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 EN steel grade S235J0 material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,EN steel grade S235J0 material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled EN steel grade S235J0 material products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the EN steel grade S235J0 material rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

30CrMo 35CrMo 25CrMo4 42CrMo4 and so on CrMo steels have good mechanical properties and hydrogen resistance at room temperature and high temperature. The main alloy elements in CrMo steel are molybdenum, chromium, vanadium, silicon, boron, etc. Molybdenum is a very important alloy element in the hot strength steel. It can significantly improve the hot strength of the CrMo steel, maintain sufficient strength at high temperature, refine the grains and prevent the overheating tendency of the CrMo steel, EN steel grade S235J0 material.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
