SelectAlloy 316L-AP is an all position electrode composed of 19% chromium, 12.5% nickel, 2.5% molybdenum and a maximum of 0.04% carbon. The molybdenum improves pitting resistance and provides increased creep resistance. The low carbon minimizes carbide precipitation which helps resist intergranular corrosion.

APPLICATIONS: SelectAlloy 316L-AP is utilized to weld Type 316 stainless and other similar alloys, such as ASTM A743 and A744, as well as Types CF-8M and CF-3M. It has broad applications in pulp and paper, textile and chemical processing equipment, furnace parts and parts exposed to marine environments.
