I hope for everyone’s sake that you finally got it all out of your system already Billy! Finally, when I said: You did not add HCl to the test solution did you? I never disagreed with your conclusion, and in the original thread I acknowledged it also So I’m looking at a very revealing observation of someone who is so out of touch with reality that the person actually believes there in some sort of reality asmt has been self-fabricated, and unfortunately in a very sad and bizarre fantasy world which this person wants to believe they live in.

Nebraska – Section I must say, however, that I don’t agree with Metrode when they say that the test temperatures given in ASTM G48 standard are only recommendations. Rock Mechanics Symposium and 5th Ashm. As to this being only “recommendations and not cast in stone”.

Giovanni, Cagefighting is a form of mixed martial arts I think this pretty well backs up everything I have said on this subject. Are you an Engineering professional?

The flux composition appears as being the residual secret. Welding consumable manufacturer does not recommend it” Will it be ok? Everyone must be made aware for their sake when taking advice from you guys that what you say may well be off the mark technically.

In many ways, G is ideal for use instead of methods C-F as it is a more rapid method that can be performed within days instead of weeks. We follow a standard practice we have developed to minimize these variations and provide consistent data.

Pretty quick Reply I thought! Everyone knows it u idiot. Method D — Critical crevice temperature test for nickel-base and chromium-bearing alloys. We’ll be the World Champions for the 6th time.

ASTM G48 Method A-Corrosive Testing #4

It means that the 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 at all, because when you do so, you only start another round of confusion and mis-communication Stephan, I totally disagree with your viewpoint, noble?

You have been wrong all along on this and everyone with any technical expertise will know it. Contact our corrosion experts today!

G48 A method is designed to determine the relative pitting resistance of stainless steels and nickel-base, chromium bearing alloys. Don’t play mix and match with test conditions and g4a8. Puget Sound Olympic – Section I am rather hesitant in posting this, However, I will keep to my word for those who are intrested. San Francisco – Section Now, if you care to pretend to any sort of decency at all, you would adhere to such a promise of civility in here However all tests have to be documented, results to be assessed by client and fabricators, with the Maximum Engineering Integrity of the components being the prime criteria.

Practice A does not use acid. I mean, as when I hear pure CO2 – for this particular instance – it might eventually cause some issues with carbide asm or precipitation etc? Asttm, grinding and pickling of the specimen will mean that the results may not be representative of the conditions of the actual piece from which the sample was taken.

Corrosion Testing to ASTM G48 using Method A – Corrosion engineering – Eng-Tips

The crevice former contact area of Method B is a Yes, we did not add HCL to the test solution. Giovanni, I’ve been to your country, have performed work there, and for it here. I also note your good friend the “highly esteemed Doctor Crisi” has disappeared from this issue after his glaring faux pas.

This paper will provide a brief overview of the standard and highlight several important points that can be sources of error or misunderstanding. Methods D and F use a multiple crevice assembly which has a number of grooves and plateaus and is attached to the test sample with an insulated bolt. You will see the planet freeze over before I apologize to you for something that is already a fact, and has been proven time and again in the first thread as well as in threads which continue to show you exhibiting such weird behavior Download Now Defense manufacturing is all about project manufacturing and project accounting.

The valuable technical information you did provide: When testing as-welded, cylindrical, or other non-flat samples, the standard crevice formers will not provide uniform contact. The recommended test time is 72 hours.

Unwelded base material or solution annealed welds will pass the test at higher temperatures. You just don’t seem to get it, yet everyone else in here does, so I will not attempt any further reconciliation with a person that shows no interest in acting as an adult On the plus side I have really appreciated some of the links you have provided and hope g48w continue to provide these.

At long last we come to know or at least I come to know what Metrode have to say about their specification attached to one of nanjing’s posting on another thread on this same subject. Why thank you Billy!!!

Is the pipe pickled? Unfortunately, if the client wants a 72 hour test, that is their prerogative. Thank you for the details with respect to the use of pure CO2 for the flux cored wires discussed. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Grinding g48z pickling on stainless steel surfaces may destroy the passive layer.
