The data collected assures you that the material is within the standard curves as specified in ASTM-A Astm a255 the end-quench test the astm a255 of hardening is the distance along the specimen from the quenched end which correlates to a given hardness level.

The Certified Material Test Report shall state the method of hardenability determination. The values given in parentheses astm a255 for information only.

The test consists of water quenching one end of a cylindrical test specimen 1. Vickers Hardness 5Kg and 10Kg.

This astm a255 method assures that the material you are using is going to respond correctly to heat treatment. The values given in parentheses are mathematical conversions to SI units that are provided for information only and astm a255 not considered standard. 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 a25. These curves give High and Low values which material should fall into.

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 two test methods include the quantitative end-quench or Jominy Astm a255 and a method for calculating the hardenability of steel from the chemical composition based on the original astm a255 by M.

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. The sample is then brought back up to austenitizing temperature as astm a255 for alloy, and end quenched with a specialized holder for the end quench to occur.
