Gas Cylinder Steel

    China grade cylinder steel plates are specially developed for the manufacturing of gas cylinders, LPG cylinders, pressure vessels and other high-pressure containers. These steels are designed to provide a good balance of strength, toughness, weldability and formability, meeting the strict requirements of cylinder forming and safe pressure service.

    Common Chinese grades include HP235, HP265 and HP295, which are widely used in the production of welded gas cylinders and liquefied gas containers. With stable mechanical properties and excellent cold forming performance, these materials can be processed through cutting, bending, deep drawing and welding to produce reliable cylinder shells with consistent quality.

    At CEHE STEEL, we supply China grade cylinder steel plates with controlled chemical composition, reliable mechanical properties and customized sizes according to customer requirements. The plates are suitable for manufacturers of LPG cylinders, industrial gas cylinders, pressure equipment and related fabrication industries worldwide.

    China grade cylinder steel plates such as HP235, HP265 and HP295 offer good forming performance, making them suitable for deep drawing, rolling and other forming processes used in gas cylinder production. The material can maintain stable shape and quality during fabrication.

    Cylinder steel plates are designed to withstand internal pressure conditions during service. With controlled mechanical properties and consistent strength performance, they provide reliable support for LPG cylinders, industrial gas cylinders and other pressure containers.

    HP235, HP265 and HP295 grades are produced with strict control of chemical composition and rolling processes, ensuring uniform performance across different plate sizes and production batches.

    China grade cylinder steel plates are widely used for LPG cylinders, compressed gas cylinders, liquefied gas containers and other pressure equipment where safety and durability are required.

    We provide cylinder steel plates in different thicknesses, widths and lengths according to customer requirements, supporting both standard orders and customized fabrication projects.

    Steel plates can be supplied with mill test certificates (MTC), chemical composition reports and mechanical property data to help customers complete quality verification and project documentation.

    Cylinder steel plates require strict control during manufacturing because they are directly used for LPG cylinders, industrial gas cylinders and other pressure applications. From steelmaking to final inspection, every production stage is monitored to ensure stable mechanical properties and reliable fabrication performance.

    The production starts with carefully selected raw materials and controlled chemical composition. Elements such as carbon, manganese and other alloying components are adjusted according to GB/T 6653-2017 requirements to achieve the required strength, toughness and formability.

    During hot rolling, temperature control and rolling parameters are strictly managed to ensure uniform thickness, consistent mechanical properties and good surface quality. This helps cylinder manufacturers achieve better forming performance during production.

    Cylinder steel plates can be supplied with complete inspection documents, including chemical composition, mechanical test results and production information. Mill Test Certificates (MTC) help customers complete incoming inspection and quality verification.

    With stable production management and quality inspection procedures, China grade cylinder steel plates provide a dependable material solution for gas cylinder manufacturers, pressure equipment producers and industrial fabrication companies worldwide.

    China gas cylinder steel plates are mainly produced according to GB/T 6653-2017, which specifies the technical requirements for steel plates used in gas cylinders and pressure applications. Common grades include HP235, HP265, HP295, HP325 and HP345

    The commonly used China grades include HP235, HP265 and HP295. Higher strength grades such as HP325 and HP345 are also available for applications requiring higher pressure resistance and stronger mechanical performance.

    The main difference is their strength level and application requirements. HP235 is commonly used for general gas cylinders, while HP265 and HP295 are selected for applications requiring higher strength and pressure performance.

    Yes. China gas cylinder steel plates are widely used for manufacturing LPG cylinders, liquefied gas containers and industrial gas cylinders. Their forming characteristics make them suitable for cylinder fabrication processes.

    The suitable grade depends on factors such as cylinder design pressure, manufacturing process, forming method and required mechanical properties. Customers can provide application details, and our team can recommend the appropriate grade.
