Description:

Cromarod 309MoL is a rutile flux coated electrode which deposits a 23% Cr / 12%Ni / 2.5%Mo

austenitic stainless steel weld metal. The high alloy content and ferrite level enable the weld metal to

tolerate dilution from dissimilar and difficult-to-weld materials without hot cracking or brittle structures.

Applications:

– Dissimilar joints between stainless and mild, low alloy or medium carbon steels.

– Buffer layers on mild and low alloy steels prior to overlaying with Cromarod 316L.

– Interface runs in 316L clad steels.

– Joining of medium carbon hardenable steels e.g. armour plate..
