Frequently Asked Questions

Learn more about A285 steel plate.
ASTM A285 steel plate is used for fusion-welded pressure vessels that require low or intermediate tensile strength. It is commonly used in pressure vessel, storage tank, boiler and low-pressure equipment applications where moderate strength and weldability are important.
A285 Grades A, B and C are separated by tensile strength level. Grade A has the lowest tensile strength range, Grade B is intermediate and Grade C has the highest tensile strength range within the A285 specification. The right grade depends on the pressure vessel design, required strength, thickness and project specification.
ASTM A285 steel plate is normally supplied in the as-rolled condition. This makes A285 different from some other PVQ grades that may be supplied normalized or heat-treated depending on thickness, toughness needs or project requirements.
ASTM A285 and ASTM A516 are both carbon steel pressure vessel plate specifications, but they are used for different performance needs. A285 is a low- and intermediate-tensile strength PVQ plate normally supplied as-rolled, while A516 is used for welded pressure vessels in moderate and lower-temperature service where improved notch toughness is important. A516 is often the better fit when the application requires stronger toughness performance or lower-temperature service.
A285 steel plate thickness availability depends on whether the material can meet the specification’s required mechanical properties. For heavier pressure vessel applications or projects requiring improved toughness, another PVQ grade may be more appropriate depending on the vessel design and material requirements.
