Arcaloy 308L-15 electrodes were developed for the welding of Type 304L stainless steels but can be used for many other stainless steels including Types 301, 302 & 304. They are used extensively for the welding of chemical plant equipment and may be used successfully for the welding of Types 321 and 347 stainless steels provided the service temperature is less than about 700 F(371 C). The basic coating of Arcaloy 308L-15 gives the highest resistance to cracking and excellent vertical welding characteristics. Operates on DC current only.
