An extensive literature covering the last 50 years has shown that all structural and bridge steels are potentially susceptible to strain aging. The most damage is done by cold strain itself. Strains in the 5% to 18% range can typically increase yield strength by 70% and typically increase tensile strength by 35%. Over the same strain range, tensile elongation will typically decrease by 30%. The Charpy V-notch impact transition temperatures will typically increase by 65F after similar strain… CONTINUE READING
