This standard is also available to be included in Standards Subscriptions. A visual comparison between these specimens should assist in interpretation. Combinations of alloys and test methods for which successful experience is available are shown in Table 1. It may be applied to all wrought products and weld metal. Standards Subsctiption may be the perfect solution.
For very heavy sections, specimens should be prepared to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing. An equivalent area of copper shot or chips may be used. Ordinarily, removal of more material than necessary will have little in?
This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides or nitrides in stabilized and unstabilized ferritic stainless steels.
This abstract is a brief summary of the referenced standard. A — 93 The tests can be run without interruption for the time speci? NOTE 2—Other equivalent means of specimen support such as glass hooks or stirrups may also be used.
Times longer than 24 h should be included in the test report. If there is an appreciable change in the level, repeat the test with fresh solution and a reground specimen. It may also be used to evaluate the effectiveness of stabilizing element additions Cb, Ti, etc.
ASTM A763 – 15
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. However, if preliminary results are desired, the specimen can be removed at any time for weighing. Please first log in with a verified email before subscribing to alerts.
Fresh test solution would not be needed if the test were to run 48 or 72 h. Warning—Protect the eyes and use rubber gloves and apron for handling acid. Link to Active This link will always route to the current Active version of the standard. Four practices, including Practice W, X, Y, and Z, are used for determining susceptibility to intergranular attack in ferritic stainless steel.
Preparation of Test Specimens 4. Rinsing Prior to Examination 8.
ASTM A() 铁素体不锈钢晶间腐蚀敏感性检测_百度文库
It is ideal to have all the specimens in one? Warning—Protect the eyes and face by face shield and use rubber gloves and apron when handling acid. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
C Preferred criterion, these criteria are the most sensitive for the particular combination of alloy and test. It may also be used to evaluate the resistance of high purity or stabilized grades to sensitization to intergranular attack caused by welding or heat treatments. Already Subscribed to this document.
A number in parentheses indicates the year of last reapproval. In the annealed condition, they are not subject to intergranular corrosion.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. For any studies of IGA on Types,orthe indicated test methods are suggested. The copper should be washed and degreased before use. If the document is revised or amended, you will be notified by email. This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides and nitrides in stabilized and unstabilized ferric stainless steels.
The choices are listed in Table 1. The tests can be run without interruption. A trip balance may be used. The test will not differentiate between intergranular attack resulting from carbides and that due to intermetallic phases. Different method of preparing steel test specimens are presented.
Times for steels not listed in Table 1 are subject to agreement between the supplier and the purchaser. Evaluation by Weight Loss
