S355J2G3 Carbon Steel – Specification, Composition, and Applications

S355J2G3 is a non-alloy structural steel grade widely recognized under the EN 10025 standard. It is well-known for its high tensile strength, excellent weldability, and superior impact resistance even in low-temperature environments. This steel is normalized (G3), enhancing its ductility and making it highly suitable for structural engineering applications.

📌 What is S355J2G3 Carbon Steel?

S355J2G3 is a low-carbon manganese steel grade used extensively in construction, offshore platforms, steel bridges, and machinery parts. The designation can be broken down as follows:

• S – Structural Steel

• 355 – Minimum yield strength (in MPa)

• J2 – Impact test at -20°C

• G3 – Supplied in normalized condition

This combination offers a balanced mix of strength, flexibility, and cold weather toughness, making S355J2G3 a preferred choice in heavy-duty applications.
