Combinations of alloys and test methods for which successful experience is available are shown in Table. C Preferred criterion, these criteria are the most sensitive for the particular combination of alloy and test.
In no case shall the specimen be bent over a smaller radius or through a greater angle than that speci? A — 93 Welded samples should be bent in such a manner that weld and the heat-affected zone are strained. Begin timing the test period when the solution reaches the boiling point. 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.
We have no amendments or corrections for this standard. This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides and nitrides in stabilized and unstabilized ferric stainless steels.
A trip balance may be used. It may be applied to wrought products and weld metal. 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.
Rinsing Prior to Examination 8.
Heavy specimens may require bending in a? Link to Active This link will always route to the current Active version of the standard. Please first verify your asmt before subscribing to alerts.
For any studies of IGA on Types,orthe indicated test methods are suggested. An air or hydraulic press may also be used for bending the specimens. Practice W is used as a screening test to avoid the necessity, for acceptable specimens, of more extensive testing required by Practices X, Y, and Z. Preparation of Test Specimens a73.
Different method of preparing steel test specimens are presented.
ASTM A763 – 15
This test detects susceptibility to intergranular attack associated with the precipitation of chromium carbides or nitrides in unstabilized and stabilized ferritic stainless steels.
In the annealed condition, they are not subject to intergranular corrosion. Evaluation by Weight Loss D Weight loss measurements can be used to detect severely sensitized material, but they are not very sensitive for alloys noted with this superscript and may not detect slight or moderate sensitization. Types,and are nonstabilized grades that are generally not used in the a76 or sensitized condition in other than mildly corrosive environments.
Some experience with corrosion rates of ferritic stainless steels in Practices X and Y is given in the literature 5. 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.
Originally approved in ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. However, several specimens may be tested simultaneously. Times for steels not listed in Table 1 are subject to agreement between the supplier and the purchaser.
This will ensure detection of intergranular attack resulting from carburizing of one surface of sheet material during the? Application of these standard tests to the other ferritic stainless steels will be by specific agreement between producer and user.
ASTM A() 铁素体不锈钢晶间腐蚀敏感性检测_百度文库
It may be applied to wrought products. For any studies of IGA on Types,orthe indicated test methods are suggested. For specific safety precautionary statements, see 3. For very 7a63 sections, specimens should be prepared to represent the appropriate surface while maintaining reasonable specimen size for convenience in testing.
ASTM A Sensitization Testing of Ferritic Stainless Steel
z763 Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. See Table 1 for a listing of alloys for which Practice W is appropriate. Warning—Protect the eyes and use rubber gloves and apron for handling acid. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
All traces of oxide scale formed during heat treatment must be removed. 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.
