Classification:
EN ISO 14343 G 19 9 H
AWS A5.9 ER308H
Description:
Cromamig 308H deposits a 20%Cr-10%Ni austenitic stainless steel weld metal with controlled carbon
content (0.04%-0.08%). It is designed to weld similar composition steels, used for their creep strength
and oxidation resistance at temperatures up to 800°C. Cromamig 308H is also recommended for
welding the controlled carbon stabilised grades 321H and 347H, used for structural applications at
temperatures above 400°C.
