Frequently Asked Questions

Learn more about A612 steel plate. 
ASTM A612 and ASTM A516 are both carbon steel pressure vessel plate specifications used for moderate and lower-temperature service. A612 is a high-strength carbon-manganese-silicon steel plate, while A516 is a broader PVQ plate specification available in Grades 55, 60, 65 and 70 where improved notch toughness is important. The right choice depends on the pressure vessel design, required strength, temperature service, thickness and project specification.
ASTM A612 steel plate is used for welded pressure vessels that operate in moderate and lower-temperature service. It is a high-strength carbon-manganese-silicon steel plate selected when pressure vessel applications require strength, weldability and reliable performance at lower service temperatures.
Charpy impact testing is not automatically required for every ASTM A612 order, but it may be requested when a pressure vessel application requires verified toughness for lower-temperature service or project-specific conditions. Testing requirements should be confirmed when the plate is ordered.
A612 steel plate thickness depends on the material’s ability to meet the specification’s required mechanical properties. For heavier pressure vessel applications, another PVQ grade may be more appropriate depending on the project’s design and material requirements.
