(OP)
I have prepared a TDC for ASTM A105 forged bar. Vendor has supplied material in hot rolled condition. My questions are:
1. Are forging and rolling the same operations?
2. Should the material be accepted in rolled condition?
Nars will be machined into forged fittings. Code of construction is ASME B31.1 Non BEP.

No. A 105 is very clear regarding forging.
No, you required a forging under material specification A 105. You were supplied hot rolled bar. Review
ASTM A 788 for further information related to forgings and general requirements.

Thankyou so much for the explanation. However I am confused as definition of steel forging as per SA788 allows plastic working with a ring rolling machine also.

Disagree. The work reduction and grain flow pattern in forging is more desirable than a rolled product formed where you have directionality or banding.
