Implication

This analysis compares SRC susceptibility in UNS S34751 and UNS S34709 welds, highlighting significant differences. It suggests implications for pipeline applications under varying conditions.

Key Points

Initial results indicate better SRC resistance in UNS S34751 compared to UNS S34709 at elevated temperatures.
Testing revealed more effective thermomechanical properties in UNS S34751 welds than those using UNS S34709.
A comparative analysis on weld filler choices demonstrated varying SRC susceptibility in both materials.
Microstructural examination of weld zones showed critical disparities influencing cracking behavior under stress.
