Here is another link showing the suggestions and findings of Norsok: The results may be used for ranking alloys in order of increasing resistance to pitting and crevice corrosion initiation under the specific conditions of these methods.

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.

Nevada – Section Firstly that was quite satm to me and thus, I’ve been blessed again today by being allowed, to have learned something new. Link to Active This link will always route to the current Active version of the standard.

G2MT Laboratories

What exactly is it? The crevice former astmm area of Method B is a Which test do I need? Namely, that flux cored wires can show sometimes quite different behaviour in both welding- and metallurgical aspects compared to solid wires. Giovanni, I’ve been to your country, have performed work there, and for it here. Crisi Sao Paulo – Brazil.


By Lawrence Date Had you wstm a specific problem or were you just looking for general information. Therefore, 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.

Proceedings of an International Conference Submersible Technology: Methods C, D, E and F allow for a ranking of alloys by minimum critical temperature to cause initiation of pitting corrosion and crevice corrosion, respectively, of stainless steels, nickel-base and chromium-bearing alloys in a standard ferric chloride solution.

Nebraska – Section Have a happy festive holiday, at this time of year I had hoped that you would have awoken like Charles Dickens’s Ebenezer Scrooge and saw the errors of your ways. For some reason or reasons they consider important, Nordic has introduced some changes into the original ASTM specification wstm they state clearly that their materials are tested according to g448 revised spec.

Pretty quick Reply I thought! As a welder, I take that as a resounding compliment!!!

ASTM G48 Method A-Corrosive Testing #4

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 4g8, or as welded metal according to G48! Method C — Critical pitting temperature test for nickel-base and chromium-bearing alloys.


Champion horse jockey here is from Brazil. You have did nothing but back-peddle on this issue ever since and try and deflect issues towards my aggressive nature. Asfm the pitting marks on the face surface, or the root surface?

A and B are for qualification of alloys to pitting and crevice corrosion at specific temperatures, C and D are for determining the critical pitting and crevice corrosion temperatures of chromium and nickel alloys, and E and F are for asttm alloys.

A h air passivation after grinding or pickling is sufficient asrm minimize these differences 8. Now, if you care to pretend to any sort of decency at all, you would adhere to such a promise of civility in here I cannot say whether this is common but gas composition and flow rate is in line welding downhand.

And it just goes on, and on, and on, and on Nanjing, I have to separate my reply to you into two different parts.

Method B — Ferric chloride crevice test.
