MI 309LSI (D200 PRE)

Austenitic-ferritic wire electrode for GMA (MIG/MAG) welding of dissimilar joints of stainless steels to unallyoed or low-alloyed steels, subjected to operating temperatures up to 300°C. Suitable to use also as buffer layer on carbon steel before welding with 308 and 308L to reach 304 and 304L layer. Low carbon content increases resistance to intergranular corrosion.
