Colorado – Section Advanced search Show search help. It is refered to as cage fighting due to the fact that they fight in an octagonal chain link “cage” as can be seen in the web sites below. Contact our corrosion v48 today! Nebraska – Section Which test do I need?

Testing by ASTM G48 for Pitting and Crevice Corrosion

Thank you for the details with respect to the use axtm pure CO2 for the flux cored wires discussed. North Florida – Section Other units are given in parentheses for information only. 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.

No statement can h48 made about resistance of alloys in environments that do not contain chlorides.

Grinding or pickling on stainless steel surfaces may destroy the passive layer. Publishers Content Coverage Privacy.

The only reference from the OP regarding a Cr Super Duplex metal at all was when he was referring to the grade of filler wire used for the root pass which was deposited via GTAW 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 Henry, I would have accepted your “olive branch” if you had been man enough to admit your failings on this subject and I would have respected you for that.

This is a simple immersion test where the test sample is placed gg48 a temperature-controlled solution of FeCl 3.

G2MT Laboratories

atsm For your information, on the use of CO2 when welding duplex, I attach some further information from Metrode. I respectfully disagree with it being the end of the story, since your true nature is only beginning to be revealed in here Henry, it is you who are causing the confusion here.

Methods C, D, Astn 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. I thought we at least agreed to stop hurling insults at each other starting especially in the open part of the forum Consequently, the degree of corrosion damage that occurs during testing will generally be greater than that in natural environments in any similar time period.

I would have hoped that js55 would have found a second of his precious time to chime in, as I personally don’t know anybody possessing a greater expertise with these tricky little details than even Jeff. This standard contains six methods, A through F.

The flux composition appears as being the residual secret. By Nanjing Date By Stephan Date Lyoto Machida and Anderson Sylva being the first who come to mind I believe the OP of this on-going, never ending thread actually stated that the corrosion tests were performed to Norsok Standard, quote OP: No matter what, the stake wont go down Prof Crisi The valuable technical information you did provide: I still think you do not see it.


Your t48 to conclude the topic hereby is – from my humble standpoint – more than agreeable. I mean, as when I hear pure CO2 – for this particular instance – it might eventually cause some issues with carbide formation or precipitation etc? We follow a standard practice we have developed to minimize these variations and provide consistent data.

Atm use of contoured crevice formers may be considered in such situations, but the use of a pitting test Practices A, C, or E should be considered. Your disagreement with my viewpoint: Most people think that university professors must know all what’s written on the Book of Universe since its creation.

By CWI Date A summary of the methods is listed in Table 1 below.

Henry, do not try and worm your way out of this one. Unwelded base material or solution annealed welds will pass the test at higher temperatures. Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition.

Henry, so well said – gg48 noble! The futures history books will reflect a much different book than the present’s history.
