On the corrosion fatigue behavior of a modified SAE 4135 type steel in a H2S environment
Description
The corrosion fatigue behavior of a modified SAE 4135 steel in a H2S environment is compared to that of a standard SAE 4135 steel of the same strength level. The modification consists of an increase in molybdenum content from 0.20 to 0.75% and the addition of 0.036% columbium. It was found that the high cycle fatigue strength of the modified steel was 66% higher than that of the standard steel. The improvement is attributed to an increase in resistance to hydrogen embrittlement brought about by a higher tempering temperature which reduces the amount of phosphorous on grain boundaries, as well as the beneficial scavenging effects associated with the increase in molybdenum content and the presence of columbium
