Pressure vessel steel plates are specially developed for manufacturing boilers, storage tanks, reactors, heat exchangers, and other equipment operating under high pressure and temperature conditions. These applications require steel materials with reliable strength, good toughness, and excellent weldability to ensure long-term operational safety.

    CEHE STEEL supplies a wide range of Chinese pressure vessel and boiler steel grades, including Q245R, Q345R, Q370R, 15CrMoR, 14Cr1MoR and other grades manufactured according to Chinese standards. These steels are widely used in industries such as petrochemical, energy, power generation, and industrial equipment manufacturing.

    Compared with ordinary carbon steel plates, pressure vessel steels have stricter requirements for chemical composition, mechanical properties, and thickness performance. They are suitable for welding, forming, and fabrication processes involved in pressure equipment production.

    With cooperation from qualified Chinese steel mills, CEHE STEEL provides reliable pressure vessel steel plates with complete Mill Test Certificates (MTC), export-standard packing, and flexible supply solutions for global customers.

    We specialize in supplying Chinese boiler and pressure vessel steel plates, including Q245R, Q345R, Q370R, Q420R, 14Cr1MoR, 15CrMoR and other grades according to GB/T 713 standards. These materials are widely used in boilers, pressure vessels, storage tanks and industrial equipment.

    In addition to Chinese standard steel plates, we also provide pressure vessel materials based on ASTM, ASME and EN standards, such as SA516Gr70, SA387 and equivalent grades, helping customers meet different project specifications worldwide.

    Our boiler and pressure vessel steel plates feature stable mechanical properties, good toughness and excellent resistance to high-pressure and high-temperature working conditions, making them suitable for demanding industrial applications.

    With strong connections to Chinese steel mills, we offer reliable supply of pressure vessel steel plates with competitive pricing, flexible specifications and professional export service.

    Steel plates can be supplied with Mill Test Certificates (MTC), chemical composition reports, mechanical test results and third-party inspection support to meet customer quality requirements.

    We provide various thicknesses, widths and lengths based on project needs, helping customers optimize material usage and improve fabrication efficiency.

    The production of boiler and pressure vessel steel plates starts with strict control of raw materials and steelmaking processes. Chemical elements are carefully adjusted to achieve stable material composition and consistent plate performance.

    During production, steel plates undergo controlled rolling and heat treatment processes to obtain the required thickness accuracy, strength and toughness. Different grades may require normalizing, quenching and tempering or other heat treatment methods according to specifications.

    Each batch of steel plates is tested for key mechanical properties, including yield strength, tensile strength, elongation and impact toughness. These inspections ensure the plates meet specified requirements before shipment.

    Quality inspection includes checking plate thickness, width, length, surface condition and flatness. Any issues affecting fabrication or further processing are identified before delivery.

    Every shipment is supplied with complete quality records, including Mill Test Certificate (MTC), heat number, chemical composition and mechanical test results, ensuring full traceability from steel production to final delivery.

    For projects with strict quality requirements, we can support third-party inspection services to verify product quality and ensure compliance with customer specifications.

    The commonly used Chinese pressure vessel steel plate grades include Q245R, Q345R, Q370R, Q420R, 14Cr1MoR and 15CrMoR. These grades are mainly specified under GB/T 713 and are widely used for boilers, pressure vessels, storage tanks and industrial equipment.

    Q345R is one of the most widely used Chinese pressure vessel steel plates. It is commonly applied in the manufacturing of pressure vessels, boilers, heat exchangers, storage tanks and other equipment requiring good strength and weldability.

    Q345R and SA516Gr70 are both commonly used pressure vessel steel plates from different standards. Q345R follows the Chinese GB/T 713 standard, while SA516Gr70 is an ASTM/ASME grade. The suitable material depends on project specifications, design requirements and applicable standards.

    Yes. We can provide complete quality documents including Mill Test Certificate (MTC), chemical composition analysis, mechanical property test reports and other inspection documents according to customer requirements.

    Yes. Chinese pressure vessel steel plates are widely exported for international industrial projects. We can provide material supply, quality documentation and export support for customers worldwide.

    Some pressure vessel steel grades require heat treatment such as normalizing, quenching and tempering depending on the grade, thickness and application requirements. The specific condition is confirmed according to the applicable standard and customer specification.
