Incoloy 20 Strip

A nickel-iron-chromium alloy with additions of copper and molybdenum. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. The alloy has excellent resistance to general corrosion, pitting and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric and nitric acids. Used for tanks, piping, heat exchangers, pumps, valves and other process equipment.STANDARD PRODUCT FORMSPipe, tube, sheet, strip, plate, round bar, flat bar, forgingstock, hexagon and wire.MAJOR SPECIFICATIONSUNS N08020ASTM A 240, A 480, B 366,B 462 – 464, B 468,B 471 – B 475, B 729, B 751,B 775, B 829, B 906DIN 17744, 17750-17754ASME SA-240, SA-480, SB-366,SB-462 – SB-464,SB-468, SB-471 – SB-475,SB-729, SB-751, SB-775,SB-829, SB-906ISO 6207, 6208, 9723 – 9725LIMITING CHEMICAL COMPOSITION, %Ni ......32.0 – 38.0Fe.......RemainderCr......19.0 – 21.0Cu..........3.0 – 4.0Nb+Ta.... 8xC-1.0Mo..........2.0 – 3.0Nb.......... 1.0 max.C...........0.07 max.Mn.......... 2.0 max.P......... 0.045 max.S........ 0.035 max.Si............ 1.0 max.PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity,Ib/in3.........................................................................0.292g/cm3.........................................................................8.08Specific Heat,Btu/lb•°F.......................................................0.12J/kg•°C............................................................500Coefficient of Expansion, 77 – 212°F, 10-6in/in •°F........8.225 – 100°C, μm/m •°C.......... 14.7Thermal Conductivity, Btu •in/ft2•h•°F...............................85W/m •°C........................................... 12.3Electrical Resistivity, ohm •circmil/ft................................ 651μΩ•m.................................................1.08TYPICAL MECHANICAL PROPERTIES
