anti-gas can best be described as a sealing primer coat. So hard coat anodize does not afford better corrosion protection than Type II? Remember that I am also trying to create an electrical barrier between the Stainless and the Aluminum. That is why I am considering Type III hard coat. I am...

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...

AutoCad 2006. Please explain Links. Thanks

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, Mike

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...

In the past I have setup this up using lotus notes. It will take a programmer but it will be a very good ECR/ECN system if designed correctly. Ours integrated AutoCad docs and did automatic notifications and reminders.

We are dealing with sea water. 30 deg-130 deg F.

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)

Thanks, You can single point threads after these processes with out a problem. Tapping is a bit more risky. I have my folks using gages and pitch mics to stay where we need to.

I'm with you tunalover! Need to use truse position agages

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...

I think we need some specific details in order to help

That should read 12-20 m/min sorry

Metcut says 122-20 m/min with carbide tooling, first pass depth .5 mm last pass .013 mm. In the past I have always cut to size. Or back it off a bit and run one and check the pitch dia. Make the needed adjustments re-run the part.
