Hi,
what is the main difference between Inconel 718 and 750 ? What is the best to suit sour service and NACE requirements ?
thank you.

Neither alloy has outstanding corrosion resistance, but they are fairly good and they do have high strength.
The only alloy that would generally be considered to have similar strength and better corrosion resistance would be MP35N.

Just always remember, NACE sour service requirements only pertain to cracking in H2S containing fluids. They don't take into account corrosion, fatigue life, stress requirements, etc. for a part. These concerns need to be considered separately.
