S275J0 Structural Steel: An Upgraded Industrial "All-Rounder"

S275J0 follows the EN 10025-2 standard and belongs to low-alloy structural steel. The "275" indicates a minimum yield strength of 275 MPa, while "J0" means it meets impact test requirements at 0°C, offering better low-temperature toughness than ordinary steels.

Characteristics:

Balanced Strength and Toughness: Higher yield strength combined with low-temperature impact resistance, suitable for complex environments.

Reliable Weldability: Ensures stable weld quality and structural integrity in construction and machinery manufacturing.

Chemical Composition (typical ranges):

Carbon (C): 0.17–0.21%

Manganese (Mn): 1.00–1.60%

Silicon (Si): 0.15–0.55%

Phosphorus (P) ≤ 0.035%, Sulfur (S) ≤ 0.035%

Minor alloying elements may be added to enhance performance.

Applications:

Bridge Construction: Used for critical components like steel beams and piers.

Heavy Machinery: Suitable for frames of industrial equipment and chassis structures of vehicles.

Chemical Industry: Applied in support structures and non-pressure-bearing parts of chemical equipment, acting as a versatile material in industrial production.
