Abstract

One thousand-hr beam bending creep tests at 1000° F (537.7° C) on four, one-in. (25.4-mm) deep stainless steel specimens of seven-in. gage length with constant end moment were run. The specimens included: two of all weld metal, one of base metal and one bimetallic beam. The short time and creep bending results are compared to the results of a finite element analysis in which book values are used. The experimental results indicate some significant differences in short time properties and primary creep. The analytical results substantially underestimate the primary creep.
