E330-16
Alloy Type: A5.4, STAINLESS STEEL Covered Arc Welding Electrodes
E330-16 stainless steel welding electrodes are used to weld wrought and cast forms of stainless steel of similar chemical composition which offer good heat and scale resistance above 1800⁰F. High sulfur environments adversely affect the high temperature performance of E330-16 electrodes. The heat input has to be kept to a minimum during the welding to avoid the possibility of microfissuring.
Typical Applications: heat treatment, furnace environments
