D&H 446L is a unique electrode depositing a stainless steel weld metal having a nominal composition of 16Cr - 4.5Ni - 3.5Cu - Cb weld metal. The weld metal possesses excellent properties and attains high strength on heat treatment. It is ideally suited for welding martensitic precipitation hardening stainless steels of the type 17-4 PH etc.
