Description

1.1 This test method covers procedures for measuring, classifying, and determining the presence of decarburization and carburization in the threaded section of hardened and tempered metric steel bolts, screws, studs, and similar parts which have been heated to facilitate fabrication or to modify its mechanical properties. This test method is not intended to address products which are intentionally carburized to achieve specific results.

1.2 Two routine methods are described for measuring the limits of and determining the presence of decarburization or carburization; the Optical Method and the Microindentation Method 1. Either method is appropriate for routine examinations. The Microindentation Method 2 shall be considered the referee method.

1.3 For the purpose of these tests, there are four classes of hardened and tempered steel products for which specific measurements must be made with respect to their physical properties.

1.4 &solely-SI-units;

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
