WebIn earlier N.P.L. work on the strength of carbon steels at high temperatures, steels showing ‘normal’ and ‘abnormal’ creep properties were assessed from tests extending to 1000 … WebCreep occurs at elevated temperatures when the material permanently stretches at loads below the yield strength. Resisting creep requires complex alloys with relatively high carbon content. Generally as the temperature or load increases, higher alloy contents are required for adequate performance. Creep rate is the rate of stretching at a
