Incoloy 925 Pipes

A precipitation-hardenable nickel-ironchromium alloy with additions of molybdenum and copper. It combines the high strength of a precipitation-hardenable alloy with the excellent corrosion resistance of INCOLOY alloy 825. The alloy has outstanding resistance to general corrosion, pitting, crevice corrosion and stress-corrosion cracking in many aqueous environments, including those containing sulfides and chlorides. Used for surface and down-hole hardware in sour gas wells and for oil-production equipment.STANDARD PRODUCT FORMSTube, round bar, flat bar, forging stock and wire.MAJOR SPECIFICATIONSUNS N09925NACE MR-0175/ISO 15156ASME Code Case 2218LIMITING CHEMICAL COMPOSITION, %Ni.......42.0 – 46.0Fe.......RemainderCr.......19.5 – 22.5Mo..........2.5 – 3.5Cu..........1.5 – 3.0Ti.......1.90 – 2.40Al............0.1 – 0.5C...........0.03 max.PHYSICAL CONSTANTS AND THERMALPROPERTIESDensity,Ib/in3.........................................................................0.292g/cm3......................................................................... 8.08Melting Range, °F...................................................2392 –2490°C...................................................1311 – 1366Specific Heat,Btu/lb•°F.....................................................0.104J/kg•°C............................................................ 435Permeability at 200 Oersted (15.9kA/m).....................1.001Coefficient of Expansion, 70 – 200°F, 10-6 in/in•°F........ 7.821 – 93°C, μm/m • °C............. 13.2Electrical Resistivity, ohm •circmil/ft................................ 701μΩ•m................................................. 1.17TYPICAL MECHANICAL PROPERTIES
