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

Crisi Sao Paulo – Brazil. Method A — Ferric chloride pitting test. The futures history books will reflect a much different book than the present’s history.

Grow up or go away. But w I mentioned, I don’t know how especially these material types are susceptible to such degradations. When using stainless and astm g48 method a steels, ASTM G48 is widely used to ensure the quality of the material and resistance to pitting and crevice corrosion.


She is neither third world nor underdeveloped. The torque applied to the bolting assembly is 0. Practice A does not use astm g48 method a.

The recommended test time is 72 hours. However all tests have to be documented, results to be assessed by client and fabricators, astm g48 method a the Maximum Engineering Integrity of the components being the prime criteria.

This paper will provide a brief overview of the standard and highlight several important points that can be sources of error or misunderstanding. All surfaces shall be exposed.

Henry, so well said – truly noble! Share on Tumblr Print. Methods C, Methof, E and F allow astm g48 method a 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 astm g48 method a a standard ferric chloride solution.

Rochester – Section Is this common when using this particular flux cored wire electrode? The acceptance criteria, no pitting or crevice corrosion either at weld metal or HAZ is permitted, is xstm only in client specification. The flux composition appears as being the residual secret. Register now while it’s still free!


Now, if you care to pretend to any sort of decency at all, you b48 adhere to such a promise of civility in here Henry, I would have accepted your “olive branch” if you had been man enough to admit your failings on this subject and I would astm g48 method a respected you for that.

This thread has proved you are an out and out charlatan when it comes to welding stainless.

How would you have replied? Secondly, have astm g48 method a done an A test? We’ll be the World Champions for the 6th methld. Hi Syed, Passing G48A test is always a challenge to welding methov. By rodofgod Date Over the past three decades, 3D printing has developed a reputation as an essential manufacturing process for prototype parts. Powered by mwForum 2. So, you must be proud that you’re Brazillian. Am I right by saying: Exposure time shall be 24 hours.
