Welded gas cylinder steel is specifically designed for the safe storage and transportation of liquefied petroleum gas (LPG), compressed natural gas (CNG), and other industrial gases. From portable camping cylinders to large industrial storage tanks, these steel plates must deliver consistent mechanical properties, excellent weldability, and reliable performance under internal pressure and varying temperatures.
At Cehe Steel, we supply a complete range of Chinese welded gas cylinder steel grades under GB/T 6653-2017. Our focus is not only on meeting yield and tensile requirements, but also on critical safety performance — including low-temperature impact toughness, weld joint integrity, and dimensional accuracy for high-speed cylinder manufacturing lines.
China produces millions of gas cylinders annually for domestic and export markets. We work directly with certified mills to deliver cylinder steel that meets strict global standards. Whether you need HP295 for standard LPG cylinders, HP325 for higher pressure applications, or HP345 for industrial gas storage, our team provides technical support and full mill traceability.
We understand that cylinder manufacturing requires steel with consistent stamping performance, clean surface quality, and predictable forming 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 gas cylinder production, material safety is the first priority. The right steel ensures every cylinder meets certification requirements and protects lives.
