SA516 Grade 70 is a carbon steel plate made for boiler and pressure vessel applications.
SA516 Gr 70 is a carbon steel sheet manufactured to ASTM A516 / ASME SA516 standards
SA516 Gr 70 is a carbon steel grade under ASTM A516 / ASME SA516 standards,
SA 516 Gr 70 is a carbon steel plate grade under ASTM A516 standard, primarily used in boilers, heat exchangers, and pressure vessels. Known for its high tensile strength, notch toughness, and excellent weldability, this grade ensures reliable performance under high pressure and high-temperature environments.
It is widely recognized as the industry benchmark material for pressure vessel quality (PVQ) plates and is available in plates, sheets, and coils.
for boilers and storage tanks
for pressure vessels and steam lines
for heat exchangers and reactors
for ammonia and urea plants
for boilers and on-board tanks
custom cut-to-size plates and coils
| Property | Value | Notes |
|---|---|---|
| Tensile Strength | 485–620 MPa | Ensures durability under stress |
| Yield Strength | ≥ 260 MPa | Provides structural integrity |
| Elongation | 17–21% | Good ductility |
| Impact Tested | -20°C (Charpy V-Notch) | Optional as per project spec |
This balance of strength, ductility, and toughness makes SA 516 Gr 70 suitable for critical boiler and pressure applications.
| Element | Max % |
|---|---|
| Carbon (C) | 0.27 |
| Manganese (Mn) | 0.79–1.30 |
| Phosphorus (P) | 0.035 |
| Sulfur (S) | 0.035 |
| Silicon (Si) | 0.13–0.45 |
Low carbon + high manganese = excellent weldability + toughness.
SA 516 Gr 70 conforms to ASTM A516 / ASME SA516 specifications.
