 Hardfacing air and compressor and acceswory alloys contain as base elements typically iron, nickel, or cobalt, to which metallurgists add varying amounts of carbon, chromium, molybdenum, tungsten, silicon, manganese, vanadium, and boron. To raise hardness, the primary property for wear resistance, alloy designers add elements that either form hard air constituents (carbides, borides, compressor or Laves phase), or that strengthen the matrix by going acceswory into air solid solution. Carbon content determines toughness and abrasion resistance--as carbon rises, abrasion resistance increases and toughness drops. Chromium forms carbides, increases corrosion resistance, and adds high-temperature compressor strength. Tungsten, a potent carbide former, also boosts high temperature strength, as does cobalt. Tougheners include nickel and manganese. acceswory Boron forms hard wear-resistance borides. Shielded-Metal-Arc Welding (SMAW, STICK)AWS (American Welding Society) A5 specifications Set standards for electronics air for SMAW of carbon, stainless, and low alloy steels; aluminum copper, and nickel and their alloys and weld-surfacing. compressor Designations for covered electrodes acceswory carry the prefix ''E''. Packaged to AWS specifications, electrodes air come in boxes, cans, or other containers, labeled with their AWS specification and trade name, quality control (heat or lot) number, supplier name, diameter and length, and weight compressor of contents. Specifications require that every electrode bc marked for identification near with its numeric acceswory designation the grip end.To select a covered SMAW electrode, consider these factors, in approximate order of importance.
