Description:
Cromarod 308H is a all-positional rutile flux coated electrode which 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 creep strength and oxidation resistance at temperatures up
to 800°C. Exceptionally good arc stability, weld pool control and re-striking characteristics make it
particular suitable for pipewelding.
Cromarod 308H is also recommended for welding the controlled carbon stabilised grades 321H and
347H, used for structural applications at temperatures above 400 °C.
