Identify ASTM SA 387 GR D 1969

[irx]

Hi Everbody

A client mentioned this material ASTM SA 387 GR D - the fabrication was done in 1969. Does anybody know what is the modern equivalent of this material? Is it similar to P11 or P22? I can not find any reference in ASME II.

Thanks

I don't have ASME Section II at hand. All I know is back in the early 70's, the designation of SA 387 grades were changed from alphabetic to numeric. Grades were changed as...
Gr. B = Gr. 12
Gr. C = Gr. 11
Gr. D = Gr. 22
Gr. E = Gr. 21

The composition of ASTM A387 Grade D given in a 1972 study matches A387-99 Grade 22.
