SG295 is a commonly used carbon steel grade in the Japanese JIS G3116 standard for gas cylinders. Its chemical composition and properties are as follows:
Chemical Composition (in weight percentage) of SG295:
Carbon (C): 0.20% max
Silicon (Si): 0.35% max
Manganese (Mn): 1.00% max
Phosphorus (P): 0.03% max
Sulfur (S): 0.03% max
Standards of of SG295:
JIS G3116: This is the Japanese Industrial Standard that specifies the requirements for hot-rolled steel plates, sheets, and strip for gas cylinders.
Properties of SG295:
Tensile Strength: The minimum tensile strength of SG295 is 440 MPa.
Yield Strength: The minimum yield strength of SG295 is 295 MPa.
Elongation: The minimum elongation after fracture is 26%.
Impact Value: SG295 has a required value of 55 Joules at room temperature.
These values may vary slightly depending on the specific manufacturer and the applicable standard version, so it's always recommended to refer to the relevant documentation for precise information.
