There is a big difference in the codes between the two....
Compressed air is as benign a fluid as you can get. Use A105.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Instrument Air: Carbon steel; carbon steel + hot dip galvanising; 316(L) stainless steel
Plant Air: Carbon steel; 316(L) stainless steel
Considerations in making a choice could be such things as likelihood of water condensation, consumer requirements for cleanliness

Where is you installation site is located? If you can't give exact location, tell us nearest town location.
Is it indoor or outdoor? Above or below ground?
What is for this 40 barg = 580 psig compressed air is used? Is there any air conditioning unit installed after an air compressor?
Thanks,
Curtis
RE: Pipeline material selection
Code does not suggest Material selection. It provides the restrictions for a specific material.
You have to use your own judgement according to the location, design and operating conditions, vendor experiences, client experiences and specifications, fluid list and the list goes on and on.
Please rule out your suggestions for material selection one by one before arriving at conclusion.
Also keep in mind the cost and corrosion factor.
