S355JR Carbon Steel – Specifications, Composition, and Applications

S355JR Carbon Steel is a structural grade steel widely used in the construction and engineering industries. It belongs to the EN 10025-2 standard and offers a perfect balance of strength, formability, weldability, and impact resistance at room temperature. With a minimum yield strength of 355 MPa, S355JR is commonly used in structural applications, steel frames, and machinery parts.

📌 What is S355JR Carbon Steel?

The grade S355JR falls under the non-alloy structural steel category in EN 10025-2. The designation indicates:

• S = Structural steel

• 355 = Minimum yield strength in MPa

• JR = Impact test at room temperature (20°C)

This steel grade is supplied in an as-rolled or normalized condition and is commonly used in fabrication where strength, toughness, and ease of welding are critical.

🔬 Chemical Composition of S355JR Steel

S355JR’s low carbon content provides excellent weldability without the need for pre- or post-welding heat treatment.

🔩 Mechanical Properties of S355JR Carbon Steel

These properties make S355JR ideal for structural fabrication and load-bearing components.
