17-4PH SS Steel
17-4PH SS Steel
(OP)
Hi Dear all,
i have generally used 17-4 PH ss for valve stem for high strength and corrosion resistance for valve stem. But is it good for salty atmosphere?i have little doubt.
Which material good for above atmosphere?

15-7PH would be a modest improvement in corrosion resistance.
But if you need that strength level (>175ksi) and good resistance to crevice corrosion and SCC you will need to look at an age hardening Ni alloy like 718.

There is actually a great alloy for this, SCF-19, but I don't think that you can get heavily cold worked bar in this grade. It is a high strength 6%Mo austenitic.
