Carbon and Sulfur Analysis.

Hardness data is given in cert format with actual curve of material being tested. Wilson Hardness Conversion Chart.

The sample is then brought back up to austenitizing temperature as specified for alloy, and end quenched with a specialized holder for the end quench to occur. This testing is indented zstm determining the hardenability of steels. In the end-quench test the depth of hardening is the distance along the specimen from the quenched end which correlates to a given hardness level. This testing can be done on a sub-sized sample which does not meet the standard size bar dimension as governed by Appendix X1.
