Like what you saw? Which one do you need? The available pitting and crevice testing methods include:.
ASTM G48 – 11(2015)
Method E — Critical pitting temperature test for stainless steels. You need to log in before adding standards to the monitoring service. Method D — Critical crevice temperature test for nickel-base g48-1 chromium-bearing alloys.
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.
Standards monitoring is a free service designed for you who wish to be asmt of changes to or new editions of the standards required in your work.
Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Methods A and B are designed to cause the breakdown of Type at room temperature. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Method F — Critical crevice temperature test for stainless steels. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Method B — Ferric chloride crevice test. If you need to be able to add standards b48-11 the monitoring service, you must register as a user with your own username and password.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. However, the G48 test is meant for ranking or qualification, and not as designed for determining a corrosion rate over time.
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.

This ensures that you are always up-to-date and saves you both time and money. Which test do I need? Grinding or pickling on stainless steel surfaces may destroy the passive layer.

The available pitting and crevice testing methods include: There are 6 Methods: Read more about subscriptions. This service is not available if you are a URL user g488-11 you do not log in with an email address. Our lab g8-11 all 6 methods of this test as well as ASTM G, the electrochemical method for similar analysis.
When using stainless and duplex steels, ASTM G48 is widely used to ensure the quality of the material and asym to pitting and crevice corrosion.
The 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.
