Boiler and pressure vessel steel is specifically designed for the most demanding applications in energy, petrochemical, and industrial sectors. From steam boilers, pressure vessels, and heat exchangers to nuclear reactor components, gas storage tanks, and chemical processing equipment, these steel plates must deliver excellent high-temperature strength, creep resistance, fracture toughness, and reliable weldability under extreme pressure and temperature conditions.

  At Cehe Steel, we supply a complete range of Chinese boiler and pressure vessel steel grades under GB/T 713 series (Parts 2, 3, 4, 5, and 6). Our focus is not only on meeting tensile and yield requirements, but also on critical performance — including high-temperature creep resistance, low-temperature impact toughness (down to -70°C), and excellent weldability for thick-wall equipment.

  China is the world's largest manufacturer of pressure equipment, and we work directly with certified mills to deliver boiler steel that meets strict global standards. Whether you need Q245R for general pressure vessels, Q345R for medium-temperature applications, 09MnNiDR for low-temperature storage tanks down to -70°C, or Cr-Mo grades for high-temperature hydrogen service, our team provides technical support and full mill traceability.

  We understand that pressure vessel manufacturing requires steel with consistent mechanical properties, clean surface quality, and predictable forming and welding behavior. That's why we place equal importance on non-metallic inclusion control, grain size uniformity, and impact energy stability — not just the steel grade.

  In pressure equipment manufacturing, material integrity is a matter of safety. The right steel ensures every vessel meets certification requirements and operates reliably for decades.
