ASTM A255 – Standard Test Methods for Determining Hardenability of Steel
These test methods cover the identification and description of test methods for determining the hardenability of steels.
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. A. Grossman.
The selection of the test method to be used for determining the hardenability of a given steel shall be agreed upon between the supplier and user.
