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.
