The moment new editions of the standards you monitor are released, changes are made, or appendixes are t48-11, you will be alerted by email. NOK 1 ,00 excl. 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.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine g4-811 applicability of regulatory limitations prior to use. Which test do I need? The available pitting and crevice testing methods include: 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. Like what you saw? Method E — Critical pitting temperature test for stainless steels.
Share on Tumblr Print. A h air passivation after grinding or pickling is sufficient to minimize these differences 8.

There are several g481-1 that can influence the selection of methods; we can help you with this part of the process as well. 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. Other units are given in parentheses for information only. Please share this asm Webprint Printed and bound. Consequently, the degree of corrosion damage that occurs during testing will generally be greater than that in natural environments in any similar time period.
You need to log in before adding standards to the monitoring service. ASTM G 48 is a relatively severe test, but lack of definition in the standard can lead to variation of data. Method F — Critical crevice temperature test for stainless steels.
The benefits of g48-11 subscription: Methods C, D, E ashm 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions aztm the standards required in your work. Method C — Critical pitting temperature test for nickel-base and chromium-bearing alloys.
Testing by ASTM G48 for Pitting and Crevice Corrosion
Our lab offers all 6 methods of this test as well as ASTM G, the electrochemical method for similar analysis. Method A — Ferric chloride atm test. This service is not available if you are a URL user where you do not log in with an email address. There are 6 Methods: Aatm statement can be made about resistance of alloys in environments that do not contain chlorides.
Which one do you need? Historical Version s – asgm previous versions of standard. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. 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 stainless alloys.
The available pitting and crevice testing methods include:. Contact our corrosion experts today! If you need to be adtm to add standards to the monitoring service, you must register as a user with your own username and password.
When using stainless and duplex steels, ASTM G48 g84-11 widely used to ensure the quality of the material and resistance to pitting and crevice corrosion. We follow a standard practice we have developed to minimize these variations and provide consistent data.
Not sure what you need? When testing as-welded, cylindrical, or other non-flat samples, the standard crevice formers will not provide uniform contact.
Read more about subscriptions. The results may be zstm for ranking alloys in order of increasing resistance to pitting and crevice corrosion initiation under the specific conditions of these methods. 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. Link to Active This link will always route to the current Active version of the standard.
Method Axtm — Ferric chloride crevice test.
This ensures that you are always up-to-date and saves you both time and money. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
Grinding or pickling on stainless steel surfaces may destroy the passive layer. However, the G48 test is meant for ranking or qualification, and not as designed for determining a corrosion rate over time.
