Application
ER347SI is a columbium stabilized stainless steel welding wire used to weld Types 321 and 347. Addition of columbium reduces the possibility of chromium carbide precipitation and consequent inter-granular corrosion. ER347SI is recommended if the weld metal is to be subjected to high temperatures above 750ºF.

Application
ER330 is used to weld cast and wrought material of similar chemical composition. The weld metal provides excellent heat and scale resistance up to 1800ºF. However, high sulfur environments may adversely affect elevated temperature performance. This being a fully austenitic alloy, low heat input is necessary.
