It is similar to ER 307 type suitable for joining work-hardenable steels, armor plate, austenitic stainless manganese steels, free-machining steels (such as ASTM 303) and stainless Cr steels with max. 18% Cr. The grade is used, for example, in the automotive industry for joining dissimilar steels as well as tractor trailers and passenger rail cars. It is also suitable for overlay welding on carbon and low-alloy steels. It is used for MIG/MAG welding.
