Welding wire ER307Si

DESCRIPTION

Welding wire ER307Si is a filler material type with increased managanese 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. Grade has corrosion resistance similar to that of the of the corresponding parent metal. For joints between non alloyed or low alloyed steels and stainless steels, resistance to corrosion is of secondary importance.
