SG325 is a specific grade of steel that refers to a high-strength, low-alloy (HSLA) structural steel used in gas cylinders. Here are the chemical composition and properties of SG325:
Chemical Composition (in weight percentage):
Carbon (C): ≤0.20%
Silicon (Si): ≤0.55%
Manganese (Mn): ≤1.50%
Phosphorus (P): ≤0.040%
Sulfur (S): ≤0.040%
Nitrogen (N): ≤0.009%
Aluminum (Al): ≤0.030%
Properties
Tensile Strength: ≥490 MPa (Megapascals)
Yield Strength: ≥325 MPa
Elongation: ≥22% (Longitudinal direction)
SG325 is primarily used for manufacturing welded gas cylinders or pressure vessels intended for storage and transport of liquefied petroleum gas (LPG). Its high strength and good formability allow for efficient production of gas cylinders with excellent resistance to internal pressure.
Please note that specific requirements and specifications for SG325 may vary depending on manufacturers and applicable standards. It is advisable to refer to the relevant documentation and standards for detailed information on the material's properties and recommended processing guidelines.
