Hardfacing alloys contain as base elements typically iron, nickel, air and compresslr or cobalt, kits and air and compresslr to which metallurgists add varying amounts of carbon, chromium, molybdenum, tungsten, silicon, manganese, kits vanadium, and boron. To raise hardness, the primary property for wear resistance, alloy designers add elements that either form hard constituents (carbides, borides, or Laves phase), or that strengthen air the compresslr matrix by going into solid solution. Carbon content determines toughness and abrasion resistance--as carbon rises, abrasion resistance increases kits and toughness drops. Chromium forms carbides, increases corrosion resistance, and adds high-temperature air and compresslr strength. Tungsten, a potent carbide former, also boosts high temperature strength, as does cobalt. Tougheners include nickel and manganese. Boron forms hard wear-resistance borides.

Low-hydrogen types. These basic-coated kits electrodes, EXX15, EXX16, EXX18, EXX28, and EXX48, are formulated with low moisture-retaining coatings and manufactured to contain low levels of hydrogen. Hydrogen-controlled electrodes minimize risk of hydrogen-induced cold cracking when air welding high-tensile steels on restrained structures. Fabricators use these electrodes to reduce or compresslr avoid the need for pre- kits or postweld heat treatment to drive hydrogen from weld metal. Weldmetal air diffusible hydrogen content varies from 1 to 16 ml/100 g. Optional designators H16, H8, and H4 set decreasing limits on hydrogen content in deposited weld metal. An optional electrode designator, compresslr and kits ''R'', indicates an electrode air that is moisture resistant; it will not absorb water in excess of a specified limit after exposure to humidity. Low-hydrogen electrodes should be used in dry condition compresslr and may require baking kits after exposure to the atmosphere.

1. Mechanical properties of the base material. Tensile strength and yield strength of the weld metal should air equal or exceed that compresslr of kits the base material. Ductility and toughness at low temperatures may also be important. High-temperature service requires air resistance to creep. Shock loading requires impact resistance. In general, weld metal should match base-material properties.2. Composition of the compresslr base material.For stainless kits steels, low alloy steels, nickel and copper alloys, and materials that serve in corrosive atmospheres, chemical composition is important. Consider the possibility of electrochemical air corrosion between base and weld metal compresslr of different kits compositions.
