Heat to heat variations in the creep rupture strength of a modified AISI 316 grade stainless steel
- 1. Reactor Research Centre, Kalpakkam (India)
Description
A modified AISI 316 grade stainless steel has been used as the construction material for a large number of structural components for the Fast Breeder Test Reactor. The creep rupture properties of this material belonging to three different heats have been studied at temperatures of 823, 873 and 923 K in the stress range of 120 to 300 MPa for test durations up to 60,000 hours. Considerable variations in the creep rupture strength were observed from one heat to another, at all the three temperatures. The scaling of applied stress with the ultimate tensile strength at the corresponding temperatures, however, reduced the heat-to-heat variations to some extent. The heat-to-heat variations are attributed to differences in the amount of interstitial solutes in the steel as well as in grain size. (author)
