Original metal trade vintage catalog for ALLEGHENY LUDLUM STEEL CORPORATION. General offices were located in Brackenridge, PA. Principal products were Tool, Stainless, Carbon and Electrical Steels, Carbide and Alloy Metals. Contains numerous technical charts, including a Stainless Steel Finder chart of eleven different Allegheny metal grade types, and Elextrial Materials - Products for the Electrical Industry. Unbound from a large post-war 1945 engineering catalog, this unique old four page technical specifications brochure would display beautifully matted and framed. A fantastic addition to your retro metal library. Pages may be detached and contain a small amount of residual glue on edge.
