Does anyone have a copy of section VIII for a vessel built in 1967? Can you tell me if SA-212 was an approved material? What was the allowable stress at 650 F?

A212 was discontinued in 1967, replaced by A515 and A516, according to one index that I have. However, remaining stock continued to be used.
The 1965 edition of VIII which would have been used for a vessel built in 1967 lists the allowable stress from -20°F to 650°F as 16,250 psi for the (rarely seen) A grade and 17,500 psi for the (commonly used) B grade.
