Product Description

HBENiFe-CI

in accordance with AWS A5.15 ENiFe-CI

 

 

Used for welding of high-hardness grey cast iron and graphite cast iron as well as for joining cast irons to mild steels.

It is also readily used for the repair of castings.

The welds are moderately hard and require carbide tipped tools for machining.

 

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