 Hardfacing Air alloys contain as base elements typically iron, nickel, or cobalt, to which Compresslr metallurgists add varying amounts of carbon, chromium, molybdenum, Kit tungsten, silicon, manganese, vanadium, and boron. To raise hardness, the primary property for wear resistance, alloy designers add elements for that either form hard 45605 constituents 6 (carbides, borides, or Laves phase), or that strengthen the matrix by Air going into solid solution. Carbon content determines Compresslr toughness and abrasion resistance--as carbon rises, abrasion resistance Kit increases and toughness drops. for and 45605 Chromium forms carbides, increases corrosion resistance, and adds high-temperature strength. Tungsten, a potent carbide 6 former, also boosts high temperature strength, as does cobalt. Tougheners include nickel and manganese. Boron forms hard wear-resistance Air and Compresslr and Kit borides. 1. for Mechanical properties 45605 and 6 of the base material. Tensile strength Air and Compresslr yield strength Kit of for the weld metal 45605 should equal or exceed that of the base material. Ductility and toughness at low temperatures 6 may also be important. Air High-temperature service Compresslr requires Kit resistance to for creep. Shock loading requires 45605 and 6 impact resistance. Air In general, weld metal should match base-material properties.2. Composition of the base material.For stainless steels, low alloy steels, nickel and copper alloys, and materials that serve in corrosive Compresslr and Kit and for atmospheres, chemical composition is important. Consider the possibility of electrochemical corrosion 45605 between base and weld metal of different compositions 6. Searching for accessories for your air compressor?
