If I am not wrong then there is no grade for SA-105. Check again

i found it in description of fitting and flanges then i checked in A***, ASME and ASM handbook, but i haven't found reference of grades for A105.

This is old grade of A-105, right now only Grade II existed and simplified by current standard with A-105. From one fitting vendor information, the original grade are same as A-181 grade I and II.
