Armco Announces New Submerged Arc Weld Wire —Literature Available
A new submerged arc chromemoly welding wire, called W-22, is available from the Western Steel Division of Armco. Produced by Armco to the American Welding Society Specification A5.23, Classification EB3, W-22 is a low-carbon, alloy steel wire containing 2.75 percent chromium and 1.00 percent molybdenum. It provides matching alloy weld deposits, when used with neutral fluxes, to join the 2% chrome-1 moly steel — plates, pipings, and forgings.
Deposits made with W-22 are designed to meet AWS Classification EB3 in A5.23 Table 2, and normally are in the 90-ksi tensile strength range.
Steel specifications where W-22 is used include ASTM and SA A 387 Class 22, A671 Class 22 or A335 P22 pipe, and F22 and WP22 forgings.
When specified, Armco W-22 can be provided to meet the ASME SFA Boiler and Pressure Vessel Section III for nuclear material. Standard wire diameters of W-22 are 5/64, 3/32, 1/8, 5/32, and 3/16 inches. The grade is available in 60-pound coils and standard pay-off drums, or in 30- pound and 200-pound coils upon inquiry.
This new weld wire is the latest in an Armco family of submerged arc welding wires. Eight different grades ranging from W-3 to W-25 provide a selection of compositions which, when used with the proper flux and welding procedures, can meet the varied needs of designers and fabricators for strength, ductility, and impact toughness in submerged arc weldments of carbon, alloy, high-strength low-alloy, and heattreated carbon and alloy steels.
