Udimet R41 Sheet

A precipitation hardenable nickel-chromium alloy containing significant amounts of cobalt and molybdenum, along with lesser amounts of aluminum and titanium. It exhibits extremely high room and elevated temperature mechanical properties. Excellent corrosion resistance and fabricability have led to wide usage in critical aircraft engine components such as nozzle partitions, turbine blades and wheels, combustion chamber liners and structural hardware.STANDARD PRODUCT FORMSForging billet, bar, sheet and plate.MAJOR SPECIFICATIONSUNS N 07041, AMS 5545AMS 5712, AMS 5713LIMITING CHEMICAL COMPOSITION, %LimitingNi ...........BalanceCr......18.0 – 20.0Co .....10.0 – 12.0Mo ......9.0 – 10.5Al ......1.40 – 1.80Ti ...........3.0 – 3.3Fe ......... 5.0 max.B ...0.003 – 0.010C ..........0.12 max.PHYSICAL CONSTANTS AND THERMAL PROPERTIESDensity, Ib/in 3........................................................................0.298g/cm 3.........................................................................8.25Melting Range, °F...................................................2250 –2535°C ...................................................1232– 1391Specific Heat, Btu/lb • °F....................................................0.104J/kg • °C...........................................................435Coefficient of Expansion, 70 – 200°F, 10 -6in/in • °F.....6.6321 – 93°C, µm/m • °C ............11.9Thermal Conductivity, Btu • in/ft 2 • h • °F..............................62W/m • °C.............................................9.0TYPICAL MECHANICAL PROPERTIES
