ASTM A516 Steel Plate is a carbon steel plate specially designed for service in welded pressure vessels where improved notch toughness is critical. Supplied in grades A516 Grade 55, A516 Grade 60, A516 Grade 65, and A516 Grade 70, this material is widely used in boiler fabrication, storage tanks, heat exchangers, and industrial pressure vessel steel plate applications.

For projects requiring higher strength and improved toughness, A516 Grade 70 steel plate is the most commonly selected option. GNEE supplies A516 Grade 70 steel plates with competitive pricing, fast delivery, and full material traceability for all grades.

A516 Steel Plate Typical Applications
A516 steel plate is widely used in:
- Industrial boilers & steam drums
- Petrochemical pressure vessels
- LPG & LNG storage tanks
- Heat exchangers and condenser units
- Power generation equipment
- Pressure tanks and separators
- Low-temperature service tanks
A516 Grade 70 remains the most used grade for high-pressure welded structures, but many fabricators also choose Grade 60 or Grade 65 depending on the design requirements.


Normalized vs As-Rolled - A516 Steel Plate Options
Both delivery conditions are available:
As-Rolled A516 Steel Plate
Suitable for standard boiler and vessel fabrication
Shorter production time
Normalized A516 Steel Plate (Including A516 Grade 70N)
Improved toughness
More uniform microstructure
Recommended for low-temperature service, thick plates, or pressure-critical equipment
Many EPC contractors specify Charpy V-Notch impact testing for normalized plates.

FAQ
Is SA516 the same as ASTM A516?
Yes. SA516 is the ASME version, ASTM A516 is the ASTM version.
What is the most commonly used grade?
A516 Grade 70 is the most widely applied due to its strength and toughness.
When should I choose normalized material?
For thicker plates, low-temperature service, or when Charpy impact requirements are specified.
What is A516 Grade 70N?
A normalized version of A516 Grade 70. It provides better toughness and is recommended when Charpy impact requirements are specified.
What is A516 steel?
ASTM A516 is a PVQ carbon steel plate intended primarily for service in welded pressure vessels at moderate or lower temperatures, where notch toughness is important.
What is the difference between A36 and A516?
ASTM A516 (Grades 60-70) offers a yield strength of 260–290 MPa and tensile strength up to 550 MPa, combined with superior low-temperature toughness down to -45°C. In comparison: ASTM A36 – Yield strength 250 MPa, tensile 400–550 MPa, general low-temperature performance
