ER330
Alloy Type: A5.9, STAINLESS STEEL Bare, Cored and Stranded Electrodes
ER330 is used to weld cast and wrought material of similar chemical composition. The weld metal provides excellent scale and heat resistance up to 1800⁰F. ER330 is a fully austenitic alloy therefore heat input is necessary. High sulfur environments may adversely affect temperature performance.
