We are performing repairs on a pressure vessel that was fabricated in 1953 using SA-212B Firebox. I do not have a set of 1953 code books, and need to know the properties of this material. Per the U-1 it is 70000 psi, but I need to know the P number for it also. Does this material cross reference to a newer material? Any help or direction to other resources would be appreciated.
