Chemical Composition:

The chemical composition of S355J2 is carefully balanced to provide the desired mechanical properties. The typical chemical composition is as follows:

· Carbon (C): ≤ 0.22%

· Silicon (Si): ≤ 0.55%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.025%

· Copper (Cu): ≤ 0.55%

· Nickel (Ni): ≤ 0.55%

· Chromium (Cr): ≤ 0.25%

· Molybdenum (Mo): ≤ 0.08%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.11%

Mechanical Properties:

The mechanical properties of S355J2 are as follows:

· Yield Strength: ≥ 355 MPa

· Tensile Strength: 470 - 630 MPa

· Elongation: ≥ 22%

· Impact Energy (at -20°C): ≥ 27J

Heat Treatment:

S355J2 steel plates are generally supplied in the untreated or normalized condition. Normalizing involves heating the steel to a temperature above its upper critical point and then cooling in air. This process refines the grain structure and improves the mechanical properties of the steel.

Low-Temperature Impact Test:

S355J2 is required to undergo a Charpy V-notch impact test at -20°C, which ensures that the material maintains its toughness and impact resistance at low temperatures. The minimum impact energy is specified as 27J.
