SA516 Gr.70 Pressure Vessel Applications in Petrochemical and
Energy Industries
SA516 Gr.70 is a carbon steel plate widely used in pressure vessel
manufacturing.
Basic Properties
- Material Type: Carbon steel plate for low-to-moderate temperature pressure vessels.
- Standard: ASTM A516/A516M.
- Grade: Gr.70 (minimum tensile strength of 70 ksi, ~485 MPa).
| Element | C (Carbon) | Mn (Manganese) | P (Phosphorus) | S (Sulfur) | Si (Silicon) |
| Content | ≤0.30% | 0.85–1.20% | ≤0.025% | ≤0.025% | 0.15–0.40% |
- Low S/P content: Ensures good weldability and resistance to
brittle fracture.
Mechanical Properties
| Property | Requirement |
| Tensile Strength | 70–85 ksi (485–585 MPa) |
| Yield Strength | ≥38 ksi (≥260 MPa) |
| Elongation | ≥21% (50mm gauge length) |
| Impact Toughness | Compliant (e.g., -46°C test) |
Key Applications
- SA516 Gr.70 is designed for pressure vessels, commonly used in:
- Petrochemicals: Storage tanks, reactors, distillation columns.
- Energy: Boilers, steam generators, heat exchangers.
- Natural Gas: LPG/LNG storage tanks.
- Low-Temperature Equipment: Suitable for environments above -46°C (with impact testing)
International Equivalents
- Europe: EN 10028 P355GH (similar properties).
- Japan: JIS G3115 SPV490.
- China: GB 713 Q345R (similar but with slight compositional differences).
Summary of Common Types
| Type | Example | Key Use Case |
| Storage Vessel | Propane tank, air receiver | Hold pressurized fluids |
| Heat Exchanger | Shell-and-tube, boiler | Transfer heat between fluids |
| Reactor | Batch reactor, CSTR | Chemical reactions |
| Separator | Oil-gas separator | Phase separation |
| Cryogenic Vessel | LNG storage tank | Ultra-low-temperature storage |
