Creep and Stress-Rupture Properties of Austenitic Chrome-Nickel Steels in Presence of Sodium

Abstract

The creep and stress-rupture properties of two austenitic steels were ascertained at 700 deg in the presence of sodium. The research involved a creep test on X8CrNiMoVNb1613 and NiCr 3020 tubes filled with sodium. We observed no sodium influence on the secondary creep rates of the two metals. NiCr 3020 creep strength is reduced by sodium. The tertiary creep stage of the two alloys is shortened by sodium, and this leads to a marked reduction in fracture strain.
