SG295 is a Japanese standard for hot-rolled steel sheets, plates, and strip used for gas cylinders. It falls under the JIS G3116 specification. SG295 steel is mainly used in the manufacturing of liquefied petroleum gas (LPG) cylinders and other compressed gas containers.
Properties of SG295 steel:
Chemical Composition: The typical chemical composition of SG295 steel is carbon (C) ≤0.20%, silicon (Si) ≤0.35%, manganese (Mn) ≤1.00%, phosphorus (P) ≤0.040%, sulfur (S) ≤0.040%, and residual elements such as aluminum (Al), titanium (Ti), and vanadium (V) in trace amounts.
Mechanical Properties: SG295 steel typically has a minimum tensile strength of 440-560 MPa and a minimum yield strength of 295 MPa. It exhibits good formability, weldability, and impact resistance.
Dimensional Stability: SG295 steel is produced in various thicknesses, widths, and lengths to meet specific requirements for gas cylinder manufacturing.
Surface Quality: SG295 steel should have a smooth and clean surface without significant defects or imperfections that could affect the integrity of the gas cylinders.
As an important material for gas cylinder production, SG295 steel undergoes strict quality control procedures to ensure it meets the necessary standards and specifications. It is essential to follow applicable safety regulations and guidelines when handling and using gas cylinders made from SG295 steel to ensure proper performance and safety.
Note: It's always advisable to refer to the specific JIS G3116 standard or consult with the manufacturer for precise information regarding SG295 steel and its properties, as variations may exist depending on the manufacturing process and product forms.
