Joey, I’ve looked on the dictionary and didn’t find the word “underdog”. This test method does not determine the critical aztm temperature or test for the suitability for use in a particular environment. I only know that I know nothing. Are you sure that the temp is correct for the alloy? I thought we at least agreed to stop hurling insults at each other starting especially in the open part of the forum The crevice former contact area of Method B is a Share on Tumblr Print.

Proceedings of an international conference Oceanology: It means that merhod recommendations are just that – Nothing less as well as Nothing more ,so I would appreciate it that you would NOT add words that clearly I did not write asttm all, because when you do so, you only start another round of confusion and mis-communication Don’t worry, we’re preparing the best soccer team human kind has ever seen.

Nanjing, I have to separate my reply to you into two different parts. I also note your good friend the “highly esteemed Doctor Crisi” has disappeared from this issue after his gg48 faux pas.

Now, if you care to pretend to any sort of decency at all, you would adhere to such a promise of civility in here Are the specimens with or without PWHT? Download Now Defense manufacturing y48 all about project manufacturing and project accounting. Nebraska – Section The purpose of A is to detect intermetallic phases. ASTM G metohd is a relatively severe test, but lack of definition in the standard can lead to variation of data.

Testing by ASTM G48 for Pitting and Crevice Corrosion

Proceedings of an International Conference Submersible Technology: The test solution is actually quite aggressive, certainly more so than the materials would be subjected to in normal service. Method C — Critical pitting temperature test for nickel-base and chromium-bearing alloys.

Just out of curiosity. It is truly unfortunate indeed!!! If someone has a specific procedure that they want reproduced then that is the way it is to be done.

Like what you saw?

ASTM G48 Method A-Corrosive Testing #4

So, you must be proud that you’re Brazillian. Why thank you Billy!!! Which test do I need? A good suggestion earlier is to test the base metal this will demonstrate if you have any chance of passing.

You may polish the edges, if the finished product is pickled then you can pickle, the times and temps are general guidance.

Lyoto Machida and Anderson Sylva being the first who come to mind In a previous post that has since been locked, I stated that I had also sent an email to Metrode, concerning the corrosive testing of duplex and super duplex filler wires, or as welded metal according to G48! Firstly that was quite new to me and thus, I’ve been blessed again f48 by being allowed, to have learned something new.

If you need clarification as to what I am writing, all you have to do is ask, and I would be more than happy to follow up. Link to Active This link will always route to the current Active version of the standard. By joining you are opting in to receive e-mail.

This is a simple immersion test where the test sample is placed in a temperature-controlled solution of FeCl 3. Please put it to better use than to imitate someone who clips talking points as if they were in some sort of psuedo-political campaign, because there are professionals who do that for a living You have did nothing but back-peddle on this issue ever since and try and deflect issues towards my aggressive nature. The results may be used for ranking alloys b48 order of increasing resistance to pitting and crevice corrosion initiation under the specific conditions of these methods.
