| Phosphorus (max) | 0.035% |
| Sulfur (max) | 0.035% |
| Aluminum (min) | 0.015% |
Mechanical Properties:
| Property | Value |
|---|---|
| Yield Strength (min) | 235 MPa (34 ksi) |
| Tensile Strength | 400-520 MPa (58-75 ksi) |
| Elongation (min) | 24% in 2″, 21% in 8″ |
Grade E steel is commonly used in:
Its moderate strength and excellent low-temperature toughness make it suitable for various marine structural applications.
Grade E steel is typically manufactured as plate steel. Available dimensions include:
| Grade | Yield Strength (min) | Impact Test Temperature |
|---|---|---|
| A | 235 MPa | 68°F (20°C) |
| B | 235 MPa | 32°F (0°C) |
| D | 235 MPa | -4°F (-20°C) |
| E | 235 MPa | -40°F (-40°C) |
Grade E offers superior low-temperature toughness compared to other grades, making it suitable for a wider range of operating conditions.
Grade E undergoes rigorous testing, including:
