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.
