Green Future of SG325 Gas Cylinder Steel

JIS G 3116 SG325 steel, a high-strength, low-alloy material, is paving the way for a sustainable future in gas cylinder manufacturing. Designed to meet the Japanese Industrial Standard (JIS G 3116), SG325 is ideal for welded cylinders storing high-pressure gases like propane, butane, and LPG, supporting eco-friendly applications in energy, chemical, and transportation sectors.

With a minimum yield strength of 325 MPa and tensile strength of 490–620 MPa, SG325 gas cylinder steel ensures durability and safety. Its low-carbon composition (≤0.20%) and controlled impurities enhance corrosion resistance, reducing maintenance and extending cylinder lifespan, which minimizes material waste. The steel’s recyclability aligns with circular economy principles, as it can be repurposed without significant loss of properties.

Hot-rolled SG325 gas cylinder steel, available in thicknesses of 1.6–6 mm and widths up to 2000 mm, optimize material efficiency during production. The alloy’s excellent weldability and formability, supporting processes like gas metal arc welding (GMAW), enable precise manufacturing with minimal energy waste. Surface treatments like pickling further enhance durability, reducing environmental impact.

SG325 gas cylinder steel role in clean energy applications, such as cylinders for hydrogen or compressed natural gas (CNG), positions it as a key player in the transition to greener fuels. Certified to JIS G 3116, SG325 combines performance with sustainability, offering manufacturers a cost-effective, environmentally responsible solution. By supporting safer, longer-lasting cylinders, SG325 gas cylinder steel contributes to a greener future, meeting the demands of eco-conscious industries worldwide.
