GEN 330 Overview
GEN 330 is used to weld cast and wrought alloys of similar chemical composition. The weld metal has outstanding heat and scale resisting properties up to 1800F (980C), except in high‐sulfur environments, as these environments may adversely affect high temperature performance. Due to its austenitic microstructure, low heat input during welding is necessary.
