Carbon structural TBT 09cupcrni-a steel for seamless steel pipe

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, TBT 09cupcrni-a steel product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.

According to the type of production, boiler tubes can be divided into seamless steel tubes and welded steel tubes. Boiler tubes are mainly used in pipelines, heating equipment, machinery industry, petroleum geological exploration, chemical industry and other fields. Because of the special purpose of the boiler tubes, the technical parameter requirements of the TBT 09cupcrni-a steel, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.

we also provide the TBT 09cupcrni-a steel welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful TBT 09cupcrni-a steel welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.

Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to TBT 09cupcrni-a steel customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
