... vessels, aircraft components, booster motors, etc. Because of its availability, high specific strength and comparatively simple heat treatment, 0.1%C–1.25%Cr–0.8%Mo–0.2%V steel was selected for the fabrication of a nozzle assembly that required welding. Convergent and ring halves of the steel...
