· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.11%

Mechanical Properties:

The mechanical properties of S355J0 are as follows:

· Yield Strength: ≥ 355 MPa

· Tensile Strength: 470 - 630 MPa

· Elongation: ≥ 22%

· Impact Energy (at -20°C): ≥ 27 Joules

Heat Treatment:

S355J0 is supplied in the normalized condition. Normalizing is a heat treatment process that involves heating the steel to a temperature above its upper critical point and then cooling it in air. This process refines the grain structure and improves the mechanical properties of the steel.

Low-Temperature Impact Test:

S355J0 is tested for its impact resistance at -20°C, ensuring that the material maintains its toughness and ductility at low temperatures. The minimum impact energy required is 27 Joules.
