JIS G 3116: Steel sheet, plates and strip for gas cylinders is a standard established by the Japanese Industrial Standards Committee (JISC) for hot-rolled steel sheets and strips used in pressure gas cylinders. This standard covers four grades: SG365, SG325, SG295, and SG255. These grades exhibit high strength, good plasticity, excellent toughness, and superior workability (e.g., welding and cold working), making them high-quality steels for manufacturing safe and reliable high-pressure gas cylinders. They are primarily used in the production of industrial welded gas cylinders, medical gas cylinders, liquefied petroleum gas (LPG) cylinders, fire extinguishers, and other related applications.
