FOXcore 309L-MC is a high alloyed austenitic stainless metal-cored wire of the EC 309L type for special applications, made for dissimilar joints between high alloyed Cr and corrosion resistant austenitic CrNi(Mo) steels and mild or low-alloy steels.
The wire gives a high deposition rate and a wide, flat penetration profile with a stable spray arc, which shows on long welds and heavier walls. Its deposit has an austenitic structure, and typical work covers tanks, process installations and equipment in contact with water and steam.

After welding remove the heat tint by pickling or brushing, the oxide layer alone lowers the corrosion resistance of the joint. Check the feed roll pressure, a metal-cored wire is easier to crush than a solid one. Set the parameters for spray arc, in the short arc range a metal-cored wire loses its deposition advantage.
