Sandvik 18.8.Mn is a filler material is a filler metal of AWS ER 307 type with increased manganese content, reducing the risk for fissuring/hot cracking that otherwise can be a problem in fully austenitic weld metals. 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. Sandvik 18.8.Mn is available as wire and rods for MIG/MAG, TIG and plasma-arc welding.
