SA516 Gr 70 Pressure Vessel Applications In Petrochemical And Energy Industries

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).

ElementC (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
PropertyRequirement
Tensile Strength70–85 ksi (485–585 MPa)
Yield Strength≥38 ksi (≥260 MPa)
Elongation≥21% (50mm gauge length)
Impact ToughnessCompliant (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).
