Quantitative methods have been used to determine the time‐temperature‐transformation diagrams for high purity 0 % and 1 % Cr steels of eutectoid compositions and to determine the hardenability, tensile and impact strength of 0 % and 0.3 % Cr steels of eutectoid compositions. Cr addition raises the Ae 1 temperature and increases the incubation period for the decomposition of austenite. Jominy end‐quench tests show that Cr addition increases the hardenability of steel. Tensile and impact strengths tests show an increases in brittleness (loss in elongation) due to Cr addition.
