Dear Kapil,
The uns N08904 is introdused in those two standards are the same (SA240 TP904L and SB625 UNS N08904), but just in chemical and mechanical properties. There is too much restrictions in SB625 other than chemical and mechanical properties. If had a look on SB625 and it had some requirements for dimennsional and tolerances of products which theu are not mentioned in SA240.
Regards
