Thanks guys.
I think we will go with the A106B/C as it will do the job and the cost/benefit of the CrMo isn't there, plus the weldability and fatigue is a downside that we don't want.

We need to have some hard pipe runs fabricated for use in a large mobile machinery application.
Normal operating pressure 320 Bar. Relief valves set 380 Bar. Highly cyclic > 1,000,000 cycles per annum.
I can use XXS thickness ASTM A106B/C but would prefer to use a stronger alloy steel...
