scope:

The determination of the creep rupture properties of 2 1/4 Cr-1 Mo weld metal is necessary because of the paucity of data available. This document represents the initial reporting on the current efforts at the University of Tennessee. Stress rupture testing of 2 1/4 Cr-1 Mo weld metal was conducted at three temperatures, 850, 950 and 1050°F. The weld metals tested were deposited by the submerged arc process and the electroslag process. Subsequent phases of this program will more fully characterize the influence of welding process-procedure on the elevated temperature properties of 2 1/4 Cr-1 Mo weld metal. Publication of this report - WRC Bulletin No. 277 was sponsored by the Subcommittee on Weld Metals and Welding Procedures of the Pressure Vessel Research Council.
