HBW312

Accord to AWS E312

HBW312 was originally designed to weld cast alloys of similar composition.

It also hasbeen found to be valuable in welding dissimilar metals such as carbon steel to stainless steel, particularly those grades high in nickel.

HBW312 gives a two-phase weld deposit with substantial percentages of ferrite in an austenite

matrix. Even with considerable dilution by austenite-forming elements such as nickel, the

microstructure remains two-phase and thus highly resistant to weld metal cracks and fissures.
