SG325 Steel Coil: Ideal Choice for High-Strength Gas Cylinder Manufacturing

JIS G 3116 SG325 steel coil is a high-strength, low-alloy steel specifically designed for gas cylinder manufacturing, offering an excellent balance of strength, weldability, and durability. Conforming to the Japanese Industrial Standard (JIS G 3116), SG325 is widely used in producing welded steel gas cylinders for storing and transporting gases under high pressure, such as propane, butane, and LPG.

SG325 steel coil features a minimum yield strength of 325 MPa, ensuring robust structural integrity under high-pressure conditions. Its chemical composition, including carbon (≤0.20%), manganese (≤1.50%), and phosphorus (≤0.040%), enhances toughness and resistance to brittle fracture. This makes SG325 ideal for applications requiring safety and reliability in harsh environments.

The steel’s excellent weldability supports seamless fabrication of gas cylinders using processes like submerged arc welding (SAW) or gas metal arc welding (GMAW). Its formability allows for precise shaping into cylindrical forms without compromising strength. Available in thicknesses typically ranging from 1.6 mm to 6 mm, SG325 coils are supplied in hot-rolled condition, with optional surface treatments like pickling or oiling to enhance corrosion resistance.

SG325 steel coil is a preferred choice in industries such as energy, chemical processing, and transportation due to its compliance with stringent safety standards and cost-effectiveness. Suppliers provide SG325 steel coil in various widths (e.g., 1000–2000 mm) and coil weights, customizable to meet specific manufacturing needs. Certified to JIS G 3116, SG325 steel coil ensures high-quality performance, making it the go-to material for safe and durable gas cylinder production.
