AWS: SFA 5.4 E630-16
EN ISO CODE: 3581-A E Z R 3 2
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.
MECHANICAL PROPERTIES OF ALL WELD METAL
(Heated to 1025°C-1050°C, held for one hour, and air cooled to ambient, and then precipitation hardened at 610-630°C, held for four hours and air cooled to ambient.)
