Nimonic 80a Sheets

A nickel-chromium alloy similar to NIMONIC alloy 75 but made precipitation hardenable by additions of aluminum and titanium. The alloy has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 1500°F (815°C). Used for gas-turbine components (blades, rings and discs), bolts, tube supports in nuclear steam generators, die-casting inserts and cores, and exhaust valves in internal-combustion engines.STANDARD PRODUCT FORMSSheet, round bar, flat bar, forging stock, hexagon, wire,extruded section and plate.MAJOR SPECIFICATIONSUNS N07080BS 3076 (NA20), HR1,HR201, HR401, HR601ASTM B 637AIR 9165-37DIN 17742Werkstoff Nr. 2.4952, 2.4631AECMA Pr EN 2188 – 2191,2396, 2397LIMITING CHEMICAL COMPOSITION, %Ni........RemainderCr.......18.0 – 21.0Ti............1.8 – 2.7Al............1.0 – 1.8C...........0.10 max.Si............ 1.0 max.Cu.......... 0.2 max.Fe........... 3.0 max.Mn.......... 1.0 max.Co........... 2.0 max.B........ 0.008 max.Zr..........0.15 max.S........ 0.015 max.PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity,Ib/in3.........................................................................0.296g/cm3.........................................................................8.19Melting Range,°F...................................................2410 –2490°C...................................................1320– 1365Specific Heat,Btu/lb•°F.....................................................0.107J/kg•°C............................................................448Permeability at 200 Oersted (15.9kA/m).................. 1.0006Coefficient of Expansion, 68 – 212°F, 10-6in/in •°F........ 7.120 – 100°C, μm/m • °C.......... 12.7Thermal Conductivity, Btu •in/ft2•h•°F............................77.7W/m • °C.......................................... 11.2Electrical Resistivity, ohm •circmil/ft................................ 746μΩ•m.................................................1.24TYPICAL MECHANICAL PROPERTIES
