Chemical Composition:

The chemical composition of S235J2 is carefully controlled to ensure that the steel is strong, durable, and suitable for welding. The typical chemical composition by weight percentage is as follows:

· Carbon (C): ≤ 0.17%

· Silicon (Si): ≤ 0.55%

· Manganese (Mn): ≤ 1.40%

· Phosphorus (P): ≤ 0.045%

· Sulfur (S): ≤ 0.045%

· Copper (Cu): ≤ 0.55%

· Nickel (Ni): ≤ 0.55%

· Chromium (Cr): ≤ 0.30%

· Molybdenum (Mo): ≤ 0.10%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.05%

· Vanadium (V): ≤ 0.10%

Mechanical Properties:

The mechanical properties of S235J2 are characterized by its yield strength, tensile strength, and elongation. The minimum values for these properties are as follows:

· Yield Strength: ≥ 235 MPa

· Tensile Strength: 360 - 510 MPa

· Elongation: ≥ 22%

Heat Treatment State:

S235J2 steel plates are supplied in the normalized condition. Normalizing is a heat treatment process that improves the mechanical properties of the steel, especially its toughness and hardness. This process involves heating the steel to a temperature above its critical point and then cooling it in air.

Low-Temperature Impact Test:

S235J2 is suitable for use in sub-zero temperatures due to its good impact properties. The steel is tested at -20°C, and the minimum impact energy value is 27 Joules.
