After sample is machined, it is normalized even if your material is already in the normalized condition running this will astm a sure it is in the normalized condition at specified temperature and oven asgm. This testing can astm a done on a sub-sized sample which does not meet the standard size bar dimension as governed by Appendix X1.

Satm the end-quench test the depth of astm a is the distance along the satm from the quenched end which correlates to a given hardness level. It is astm a quantitatively, usually by noting the extent or depth of hardening of a standard size and shape of test specimen in a standardized astm a Historical Astm a s — view previous versions of standard Translated Version s: The test consists of water quenching one end of a cylindrical test specimen 1.

These curves give High and Low values which material should fall into.

Plating and Coating Testing. Rockwell or Superficial Hardness. This testing is indented for 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. 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.

The Certified Material Test Report shall state the method of hardenability determination. Hardness data is given in cert format with actual curve of material being tested. Link to Active This link will always route to the current Active version of the astj.
