The A516 / SA516 standard, its full name is “Standard Specification for Pressure Vessel Plates, Carbon Steel, for Moderate- and Lower-Temperature Service”, is widely used by designers and engineers in many market sectors particularly outside of Europe. You may also see the following variations:
ASTM A516 Gr. 65N or ASME SA516 Gr. 65N – the “N” is added to show that the steel is normalised
ASTM A516M or ASME SA516M – the “M” indicates that the material is certified in metric units
We are also stockists of plates manufactured and certified to:
ASTM A516 Gr. 60 ASME SA516 Gr. 60
ASTM A516 Gr. 70 ASME SA516 Gr. 70
ASME SA516 Gr. 65 / ASTM A516 Gr. 65 - the specification
The chemical and mechanical requirements of A516 / SA516 are very simple and these are listed below. Further complexity comes from additional supplementary requirements and end-user produced variations: needless to say, We are able to supply Grade 65 plates that will meet the most stringent specifications.
