Alternative material
Alternative material
(OP)
Please can anybody help???
I am looking for a replacement material for an exsiting component.
The material I currently have is a BE Cu material with a yield of 110000 PSI and UTS of 140000 PSI I require a replacement material with the same properties and NACE complient. But also has to be fit for service in a high Mercury well environment.
Can Anybody offer me a solution on materials available

I understand that the better your finish the more resistant the material.
Also, is it possible to use a protective coating?
RE: Alternative material
In the 1/2 hard condition has similar properties as 17-7Ph condition C. And is almost pure Ni, thus has great corrosion properties. Resistivity is roughly 4.3x10-5 ohm-cm. about 1/3 that of 17-7.
not sure about the Hg corrosion properties.

(ohyeah alloy 360 also performs well at elevated temps.)
RE: Alternative material
you could try using inconel 925, which is good with mercury and Nace complient.
A good place to source is Special metals, who produce ignots, or for material suppliers try
HOWCO or Flange Fit.
hope this is of some sort of use
RE: Alternative material
I would look at age hardening Ni alloy other than 718. Maybe 725 or even X-750.
I am not sure that alloys like 925 or a PH stainless will have enough corrosion resistance.

Corrosion never sleeps, but it can be managed.
