Product Description

HBENi-CI

in accordance with AWS A5.15 ENi-CI

 

 

Rod is used for welding of cast irons to other cast irons as well as for joining cast irons to mild steels and   stainless steels. It is also readily used for the repair of castings.

A preheat and inter-pass temperature of not less than 350°F is required during welding   to prevent cracking.
