Introduction to S355J2G3 Steel

S355J2G3 is a high-strength low-alloy structural steel widely used in engineering and construction. The "S" in its name denotes structural steel, while "355" represents its minimum yield strength of 355 MPa. The "J2" indicates good impact resistance at -20°C, making it suitable for cold climates, and "G3" refers to the normalized delivery condition, ensuring uniform mechanical properties.

This steel grade is well-known for its excellent weldability and machinability, which simplifies fabrication processes. It is commonly applied in the construction of bridges, buildings, and offshore structures where strength and reliability are paramount. Its versatility and compliance with EN 10025 standards make it a preferred choice for many industries. For projects requiring durable and resilient materials, S355J2G3 is a dependable option.
