Send for complete information. - Hot Rolled (Sheets and Strip) Fan Blades Blower Casings Fuel Oil Tanks Unit Conditioners Stoker Hoppers Armco Zincgrip A special galvanized sheet that can be severely formed without peeling or flaking of the zinc coating. Cold Rolled (Sheets and Strip) Furnace Casings Room Unit Casings Plates (Armco Ingot Iron) Smoke Stacks Coal Hoppers Breeching Unfired Pressure Vessels Low-fired Boilers Tanks " . Armco H. T. -50 A low alloy, high tensile steel possessing great strength. Used with proper design it results in weight reduction of frame-, work, tanks and similar items. Under atmospheric service conditions it has four to six times the resistance of regular steel. N Stainless Steel (Sheets, Strip and Plate) Combustion Chambers Heat Flues and Tubes Furnace Casing Trim Grilles Corrosion Resistance Fan and Blower Blades Heat Resistance without destructive scal ing up to 1600 F. or higher. Other Armco Products The grades for these applications are only a few that Armco makes. Others include copper-bearing sheets and plates and open-hearth steel, either galvanized or uncoated.

SOME FACTS ON CORROSION-RESISTANCE OF STEEL and advantages of copper-bearing Beth-Cu-Loy Beginning some twenty years ago, the American Society for Testing Materials started a number of tests to determine the corrosion-resistance in atmosphere of vari ous irons and steels. The charts at the right summarize the results to date; com pare the life, in atmosphere, of the four most generally used materials. These tests are worth remembering when buying or specifying iron or steel--they show one material, copper-bearing steel, to be defi nitely superior. - Beth-Cu-Loy, Bethlehem's copper-bear ing steel, is of the identical composition as that shown by the lower bar of each chart. It is available in the form of sheets, pipe, and plates. It costs only 3 to 5 per cent more than ordinary steel--the tests show that it has from 2 to 2^ times the resist ance to rust. It costs considerably less than open-hearth or copper-bearing iron. A.S.T.M.

Vol. 38). *No failures in copper-bearing steel sheets at last report. BETHLEHEM MAKES: Sheet Steel--all types, hot-rolled (black), coldUrolled, and galvanized-- available in Beth-Cu-Loy. Steel Pipe--all sizes and weights, buttwelded and lap-welded--available in BethCu-Loy. Ammonoduct--A new kind of pipe that has an outstanding advantage in its unusual ductility. It can be bent cold, without need for annealing, without danger of fracturing. Recommended for ammonia piping and for heater coils, water legs in furnaces and similar uses where pipe must be bent. Available in Beth-Cu-Loy. Boiler Tubes--Charcoal iron and steel. Plates--all sizes; flanged and dished heads. Available in Beth-Cu-Loy. Literature and further information on any of these products can be secured from the nearest district office or from the general office in Bethlehem, Pa. 2 4 6 8 10 12 Sheets exposed April 19, 1917; test discontinued April 16, 1928 (see Proceedings of A.S.T.M.-- Committee A-5. Vol. 28). Only 10 of 61 copper-bearing steel sheets had failed when test was discontinued. | I I M | 1 f~T I | I I I I j T`T T I | I II I /It ANNAPOLIS Copper-bearing Steel _L _L I _L 5 10 15 20 25 Sheets exposed October 17, 1916; tests still under way (see Proceedings of A.S.T.M.--Committee A-5.
