· Carbon (C): ≤ 0.20%

· Silicon (Si): ≤ 0.60%

· Manganese (Mn): ≤ 1.70%

· Phosphorus (P): ≤ 0.025%

· Sulfur (S): ≤ 0.020%

· Aluminum (Al): ≥ 0.020%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.03%

· Vanadium (V): ≤ 0.12%

· Nitrogen (N): ≤ 0.015%

Mechanical Properties:

The mechanical properties of S420N are characterized by its high strength and excellent toughness. The typical values for these properties are as follows:

· Yield Strength: ≥ 355 MPa

· Tensile Strength: 470 - 630 MPa

· Elongation: ≥ 22%

· Impact Energy : ≥ 27 Joules

Heat Treatment State:

The S420N grade is supplied in the normalized state, which provides a uniform microstructure and enhanced mechanical properties. Normalizing involves heating the steel to a temperature above its upper critical point and then cooling it in air.

Low-Temperature Impact Test:

S420N steel plates are subjected to a low-temperature impact test to ensure they maintain their toughness and impact resistance at sub-zero temperatures. The material typically meets the requirements of -20°C impact testing.
