The values given in parentheses are for information only. This test method assures that the material you are using is going to respond correctly to heat treatment. 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. Active view current version of standard. S255 Certified Material Test Report shall state the method of hardenability determination.

Historical Version s – view previous versions of standard Translated Version s: These curves give High and Low values which material should fall into.

It is measured quantitatively, usually by noting the extent or depth of hardening of a standard size and shape of test specimen in a standardized quench. This testing can be done on a sub-sized sample which does not meet the standard size bar dimension as governed by Appendix X1.

The two test methods include the quantitative end-quench or Jominy Test and a method for calculating the hardenability of steel from the chemical composition based on the original work by M. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of zstm limitations prior to use.

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

The data collected assures you that the material is within the standard curves as specified in ASTM-A The two test methods include the quantitative end-quench or Jominy Test and a method for calculating a2555 hardenability of steel from the chemical composition based on the original work by M. This testing is indented for determining the hardenability of steels.

ASTM A – The Jominy End Quench Test of Hardenability

Carbon and Sulfur Analysis. After sample is machined, it is normalized even if your material is already in the normalized condition running this will make sure it is in the normalized condition at specified temperature and oven cooled.

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. Jominy Testing This testing is indented for determining the hardenability of steels.
