Incoloy 27-7mo Sheet

An advanced 7% molybdenum super-austenitic stainless steel offering corrosion resistance in most environments superior to 6% molybdenum super-austenitic stainless steels. In many environments, alloy 27-7MO offers resistance approaching or exceeding that of much more highly alloyed materials such as INCONEL alloys 625, 22 and C-276. Applications for this alloy are found in the pollution control, power, marine, chemical processing, pulp and paper, pharmaceutical and oil and gas industries.STANDARD PRODUCT FORMSSheet, plate, bar and wire.MAJOR SPECIFICATIONSUNS S31277ASTM A 182, A 213, A 240,A 249, A 312, A 479ASME SA 182, SA 213, SA 240SA 249, SA 312, SA 479ASME Code Case 2458LIMITING CHEMICAL COMPOSITION, %Ni.......26.0 – 28.0Cr.......20.5 – 23.0Mo..........6.5 – 8.0Cu.............0.5-1.5N................0.3-0.4Fe.......RemainderMn........3.00 max.P...........0.03 max.S...........0.01 max.Si............ 0.5 max.C........ 0.020 max.PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity, Ib/in3(g/cm3)............................................0.289(8.02)Specific Heat, Btu/lb •°F(J/kg•°C).....................0.109 (454)Permeability at 200 Oersted (15.9kA/m).....................1.004Coefficient of Expansion, 10-6 in/in•°F(μm/m•°C)70-200°F (21-93°C)...................... 8.33(15.0)Thermal Conductivity, Btu•in/ft2•h•°F(W/m•°C)..... 69.8 (10.1)Electrical Resistivity, ohm•circ mil/ft(μΩ•cm)..........604 (100)Young’s Modulus, 106 psi(GPa)...............................27.7 (191)Shear Strength, 106 psi(GPa)....................................10.8 (74)Poisson’sRatio........................................................................0.29Melting Range, °F (°C)..............2460 – 2530(1350 – 1390)TYPICAL MECHANICAL PROPERTIES
