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. When hardness readings are taken on two or more? Please first log in with a verified email before subscribing to alerts. A satisfactory type of support for the standard 1. For DI in millimetres, use the metric value table. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

The test consists of water quenching one end of a cylindrical test specimen 1. 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 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.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. They should be mutually parallel and 3 the grinding done in such a manner that no change of the quenched structure takes place. The use of these equations to plot curves may result in random in?

ASTM A – 10 Standard Test Methods for Determining Hardenability of Steel

If such changes caused by grinding are indicated, new? Carbon multiplying factor 5 0. In production testing slightly longer times up to 35 min may be used without appreciably affecting results. You may delete a document from your Alert Profile at any time. Vickers Hardness 5Kg and 10Kg.

Wash the sample in hot water. Link to Active This link will always route to the current Active version of the standard. In the end-quench test the depth of astmm is the distance along the specimen from the quenched end which correlates to a given hardness level. 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. As the voice of the U. It has been found that with reasonable operating care and a well-built?

The procedure in preparing the specimen prior to hardness measurements is described in Sections 4, 5, and 6. After the quench, warm the assembly in boiling water to melt the Woods metal and remove the specimen. The sample is then brought back up to austenitizing temperature as specified for alloy, and end quenched with a specialized holder for the end xstm to occur.

The sheath shall preferably be made from a plain low-carbon steel. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Normalizing may be waived by agreement between the supplier and the user.

The Certified Material Test Report shall state the method of hardenability determination.

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 test astm a assures that the astm a you astn using is going to respond correctly to heat treatment.

We have no amendments or corrections for this standard.

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. In order to detect tempering due to grinding, the? A — 99 Determinin If negotiated between the supplier and the user, the end-quench specimen may be prepared from a given location in a forged or rolled product or from a continuous a525 billet.

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.
