What is ASTM A516 Grade 70?
ASTM A516 Grade 70 is a carbon steel plate specification built for welded pressure vessels and boilers that operate at moderate and lower temperatures. It is the highest strength grade in the A516 family, with a minimum yield strength of 38,000 psi and a tensile strength of 70,000 to 90,000 psi, and it is supplied with good notch toughness for service where crack resistance matters. That combination of strength, weldability, and toughness makes A516 Grade 70 the standard choice for pressure vessel steel plate across oil and gas, power generation, and petrochemical work.
A516 Grade 70 is often compared with ASTM A36. A36 is a structural grade for beams, frames, and fabrications that do not hold pressure. A516 Grade 70 is the right specification when the plate will be part of a pressure-retaining vessel, tank, or boiler.
A516 Grade 70 Mechanical Properties
- Tensile strength: 70,000 to 90,000 psi (485 to 620 MPa)
- Minimum yield strength: 38,000 psi (260 MPa)
- Minimum elongation: 17% in 8 in., 21% in 2 in.
- Plates over 1.5 in. thick are normalized to improve toughness
Capabilities of ASTM A516 Grade 70 Steel:
| Grade | Thickness | Width | Length |
| ASTM A516 Grade 70 | .125” – 2” | 48” – 124” | 60” – 960” |

FAQs
A516 Grade 70 is used for welded pressure vessels and boilers, along with reactors, separators, heat exchangers, and storage tanks in oil and gas, power generation, and petrochemical facilities.
A516 Grade 70 has a minimum yield strength of 38,000 psi (260 MPa) and a tensile strength of 70,000 to 90,000 psi (485 to 620 MPa)
SA516 is the ASME Boiler and Pressure Vessel Code version of the ASTM A516 specification. The chemistry and mechanical requirements match, and plate is commonly dual certified to both. Ask our team if your project calls for SA516 certification.
We supply A516 Grade 70 from .125" to 2" thick, 48" to 124" wide, and 60" to 960" long.
Yes. A516 Grade 70 offers good weldability, which is why it is a standard choice for welded pressure vessel fabrication.
