ASTM F2328 – 17
This test method covers procedures for measuring, classifying, and determining the presence of decarburization and carburization in the threaded section of hardened and tempered inch series steel bolts, screws, studs, nuts, and similar parts which have been heated to facilitate fabrication or to modify their mechanical properties. For example, if an order is placed to test for decarburization and none is found but the presence of decarburization is detected, it shall be reported on the test report that carburization was found.
Class of Decarburization 5. Therefore, limits have been established for three different product groups: You may delete a document from your Alert Profile at any time. See Practice E 3.
For example, if an order is placed to test for decarburization and none is found, but the presence of carburization astj detected, it shall be reported on the test report that carburization was found. Add to Alert PDF.
We have no amendments or corrections for this standard. Compare the image with Fig. Therefore, limits have been established for three different product groups: When either test method is v2328, both conditions will be apparent and shall be reported.
