Product Catalog

E330-16


Alloy Type:

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
