Inconel X-750 for Seawater Applications Springs
Inconel X-750 for Seawater Applications Springs
(OP)
Would the experienced material engineers and scientists of this forum please comment on the statement below:
Inconel X-750 springs - UNS N07750 (similar to Inconel 600) has no molybdenum and as such has low resistance to crevice corrosion in seawater or brine. The high velocity of seawater which seems to be associated with the springs in the non return valves will provide the optimum opportunity for this material to succeed but as a general statement this
material could not be recommended for these environments.

I agree with the previous comments. Also in my opinion it should be clearly stated which is the service, brine or seawater, chlorides contents and temperature to give a indication for a material.
I think that this paper can give you some good advise on mat sel for spring in seawater.
