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.
