Types,and are nonstabilized adtm that are generally not used in the as-welded or sensitized condition in other than mildly corrosive environments.
They should have three or four holes in them to increase circulation of the test solution around the specimen. Times for alloys not listed in Table 1 are subject to agreement between the supplier and the purchaser.
The test will not differentiate between intergranular attack resulting from carbides and that due to intermetallic phases. Wstm longer than 24 h should be included in the test report. It is important to ensure that the concentration of acid does not become more concentrated and that an adequate number of boiling chips which are resistant astk attack by the test solution are present.

It is informational only and not an official astn of the standard; the full text of the standard itself must be referred to for its use and application. Grind the cross section on wet or dry 80 or grit abrasive paper followed by successively? Please first log in with a verified email before subscribing to alerts. It is ideal to have all the specimens in one? Welded samples should be bent in such a manner that weld and the heat-affected zone are strained.
This standard is also available to be zstm in Standards Subscriptions. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Combinations of alloys and test methods for which successful experience is available are shown in Table.
NOTE 10—Cracks suspected as arising through poor ductility may be investigated by bending a similar specimen that was not exposed to the boiling test solution. It may be applied to all wrought products and weld metal. Times for steels not listed in Table 1 are subject to agreement between the supplier and the purchaser. A7763 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.
The choices are listed in Table 1. C Preferred criterion, these criteria are the most sensitive for the particular combination of alloy and test. However, in the special case of surface carburization sometimes encountered, for instance, in tubing when carbonaceous lubricants are employed it may be possible by heavy grinding or machining to remove the carburized layer completely.
Application of these standard tests to the other ferritic stainless steels will be by specific agreement between producer and user. Ordinarily, removal of more material than necessary will have little in? Already Subscribed to this document.

The choices are listed in Table 1. If there is an appreciable change in the level, repeat the test with fresh solution and a reground specimen. Your Alert Profile lists the documents that will be monitored.
This will ensure detection of intergranular attack resulting from carburizing of one surface of sheet a7763 during the? For any studies of IGA on Types,orthe indicated test methods are suggested. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Asgm method of preparing steel test specimens are presented.

Subscription pricing is determined by: Determine the maximum angle of bend without causing cracks in such material by bending an untested specimen of the same con? If any adherent copper remains on the specimen, it may be removed by a brief immersion in concentrated nitric acid qstm room temperature.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. This possibility must be considered in selecting the test method.
It may be applied to wrought products. This may be accomplished with the apparatus prescribed in 3. NOTE 7—Conversion factors to other commonly used units for corrosion rates are as follows: Shot is preferred for its ease of handling before and after the test. Begin timing the test period when the solution reaches the boiling point.
