Galvanic corrosion problems.
I have a cast Aluminum housing (alloy 380). That has been chromate converted, had an anit-gas coat applied and than an epoxy based power coat applied. When the unit is assembled there are several 17-4 ph components in the assemble. While going through the Navy...
I'd like to move the plot file styles files to a central location and have all AutoCAD seats default to that location. What do I have to change to make that happen?
Thanks,

Really need to find some info on 15-5 PH ASAP.
I talked to two metallurgist today one from AK and another from Castle and neither could really could provide any useful info. These questions apply to round bar.
Questions:
Is all 15-5 remelted (an important question)
How many and what types are...
I’m looking for some information on the salt corrosion resistance of 17-4 PH.
If there is no other scale of comparison how does it compare to 316 (I know 316 is better but how much better)
7-4 PH , solutionizing and H900 aging
Technically, when annealing and aging 17-4 PH Stainless Steel the material will contract. In my tests this contraction is about .0003” per inch.
However these processes seem to have the opposite effect on threads i.e. male threads get larger and female...
Any ideas what materials (metal or coatings for metals)can hold up to wet chlorine gas for long periods of time? We have a custmer that needs a sensor that can hold up in that environment. The units he is currently using are not do the job.
Thanks
My company is working towards becoming ROHS compliant. We build load cells and pressure transducers as a result of that, most of our product is made from 17-4 PH (good spring properties).
Is 17-4 PH compliant with ROHS standards. I guess the possible issue would be the Chromium content of the...
I want to solution anneal 17-4 in a vacuum. We have a spare tube furnace (6” tubes) that is used for semi conductor production. Our problem is that it is an atmosphere furnace. How much vacuum do I need to pull and maintain to avoid surface oxidation? Thanks!

We are testing load cells here. In the process we place a load on a dead weight tester. The dead weight tester has sperical radius contact point. Next comes a disk it has parallel loading surfaces. Then the load cell (the load cell also has a sperical contact point).
During the testing...
I use a lot of 17-4 bar in condition A. I have been told and have observed indications of the following:
The bar (1" in dia.)is annealed to condition A while in coil form then it is straighted. It is delivered with all that cold working stresses in the material.
Is this a true story?
Thanks
