S235 steel plate is a non-alloy structural steel produced in accordance with the European standard EN 10025, with three main grades: S235JR, S235J0, and S235J2.
The key distinction between these grades lies in their impact toughness at different temperatures:
S235JR is tested for impact at room temperature,
S235J0 at 0°C,
S235J2 at –20°C.
Apart from the variation in impact test temperature, the three grades share similar chemical composition and mechanical properties.
S235 steel plates are typically delivered in one of the following conditions: as-rolled, controlled rolled, or normalized, depending on application requirements.
S235JR / S235J0 / S235J2 – Chemical Composition (Max, %)
| Grade | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Nitrogen (N)¹ |
|---|---|---|---|---|---|
| S235JR | 0.17 | 1.40 | 0.035 | 0.035 | 0.012 |
| S235J0 | 0.17 | 1.40 | 0.035 | 0.035 | 0.012 |
| S235J2 | 0.17 | 1.40 | 0.030 | 0.030 | 0.012 |
Mechanical Properties (Thickness ≤ 16 mm)
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation A₅ (%) | Impact Energy (Charpy V) |
|---|---|---|---|---|
| S235JR | ≥ 235 | 360–510 | ≥ 26 | 27 J @ +20°C |
| S235J0 | ≥ 235 | 360–510 | ≥ 26 | 27 J @ 0°C |
| S235J2 | ≥ 235 | 360–510 | ≥ 26 | 27 J @ −20°C |
S235JR / S235J0 / S235J2 are non-alloy structural steels according to EN 10025-2, widely used in construction, bridges, and general engineering structures. The main difference lies in their impact toughness at different temperatures, making them suitable for various climates and applications.
