Abstract

The present invention relates generally to ultra-high strength steel and, in more particular aspects, relates to an ultra-high strength steel that is characterized by improved fatigue life resulting from the addition of sulfur to the steel in a significant amount. It has been found that fatigue life of ultra-high strength steel may be improved by the addition of at least about 0.04 percent sulfur, preferably 0.04 to 0.25 percent and most advantageously from 0.04 to 0.15 percent sulfur.
