Abstract

This paper presents the results of a series of tests designed to assess the changes in ambient temperature ductility of Alloy 800H, a 20%Cr-32%Ni austenitic steel, resulting from exposure to an aggressive carburizing environment at 1000 degrees C. A gas mixture of H-2 - CH-4 with 0.8 carbon activity has been used as the corrosive medium and post-exposure compression testing of the carburized tubular specimens has enabled the significant reduction in ductility accompanying the uptake of carbon to be demonstrated and understood.
