Laboratory test data are used to compare the properties of HK40 with those of HP alloy and its modifications with 4% tungsten and 1.25% niobium. The effects of minor compositional variables are also described. Extrapolation of stress-rupture data to long term is discussed using results from tests designed to verify the Larson-Miller parameter model and to optimize the constant in the expression.
