Stainless Steel Electrode
ER330 is used to weld cast and wrought material of similar chemical composition. The weld metal provides excellent scale and heat resistance up to 1800oF. ER330 is a fully austenitic alloy therefore heat input is necessary. High sulfur environments may adversely affect temperature performance.
