    Abstract - (Show below) - (Hide below)

    Specifies the method for determining the hardenability of steel by end quenching (Jominy test). Procedures are described by which the method is suitable for both deep and shallow hardening steels. Includes symbols, principle, apparatus, sampling and preparation of test pieces, heating and quenching of the test piece, preparation for, and measurements of, hardness after quenching, expression of results and test report. Includes 14 figures.
