Hot-Rolled SG325 Steel Coil High Performance

JIS G 3116 SG325 steel coil, a high-performance low-alloy steel, is engineered for hot-rolled production, making it a premier choice for manufacturing welded gas cylinders. Compliant with the Japanese Industrial Standard (JIS G 3116), SG325 is designed to store high-pressure gases such as propane, butane, and LPG, serving critical applications in energy, chemical, and industrial sectors.

Hot-rolled SG325 steel coil offer a minimum yield strength of 325 MPa and tensile strength of 490–620 MPa, ensuring exceptional structural integrity under pressure. The alloy’s chemical composition, with low carbon (≤0.20%), manganese (≤1.50%), and controlled phosphorus (≤0.040%), delivers superior toughness and resistance to brittle fracture. This composition also enhances corrosion resistance, protecting cylinders from environmental wear and extending service life.

The hot-rolling process optimizes SG325 steel coil formability, allowing precise shaping into cylindrical forms, while its excellent weldability supports fabrication techniques like gas metal arc welding (GMAW) or submerged arc welding (SAW), ensuring strong, leak-proof seams. Available in thicknesses from 1.6 mm to 6 mm and widths up to 2000 mm, SG325 coils can be customized with surface treatments like pickling for added durability.

Certified to JIS G 3116, hot-rolled SG325 steel coils combine strength, toughness, and corrosion resistance, delivering cost-effective, high-performance solutions for safe gas cylinder production. Its robust properties make it ideal for demanding environments, cementing its reputation as a reliable material for manufacturers worldwide.
