Select-Arc welding electrodes

Select-Arc Inc. has introduced two flux cored, austenitic stainless steel electrodes designed for welding in all positions. SelectAlloy 312-AP has a metal composition of 30% chromium, 9% nickel and 0.1% carbon. This wire produces a two-phase weld metal with substantial ferrite in an austenitic matrix which makes the weld metal very resistant to cracking, even when highly diluted. SelectAlloy 312-AP is used for the welding of dissimilar metals such as the joining of carbon steels to stainless steels high in nickel. SelectAlloy 316H-AP is composed of 19% chromium, 12% nickel, 2.5% molybdenum and a carbon content of 0.4-0.8%. The higher carbon content improves the elevated temperature strength and the presence of molybdenum augments the resistance to pitting while providing increased creep resistance. This premium electrode is utilized to weld Type 316 stainless steel and typical applications are found in the pulp and paper industry, chemical and textile processing equipment, furnace parts and parts exposed to marine environments. They are available in .045in and 1/16in diameters.
