Inconel 625 Plus
Inconel 625 Plus
(OP)
I have been required to compare the corrosion resistance of Inconel 625Plus to Inconel 725 for seawater applications (from -20F to 250F) NACE MR0175 does not provide any comparison data, it only states that these materials are suitable for chloride resistance. Does anyone know of a good source for this information?

RE: Inconel 625 Plus
Either way it will be slightly worse than for 625. The age hardening will have a negative effect on corrosion resistance.

I also know that under extremely tight crevices 625 can be susceptible to crevice corrosion.
Is there a specific concern someone is lookig into?

Alloy 625 plus is the exact equivalent grade of material to Special Metals Inconel 725.(chemistry, mech props etc)
There is a difference between Alloy 625 and Alloy 625plus.
Carpenter used to manufacture 625plus and I understand that Foroni Spa now manufacture the alloy under licence.
If you contact Foroni Metals in the UK or one of thier distributors for this grade, then they'll be able to forward you relevant data sheet for 625plus
