Applications of Inconel™ 713C

  • Inconel 713C is most commonly used for jet engine gas turbine blades.

Machinability of Inconel™ 713C

  • Machine with single–point cemented tungsten-cobalt grade and tungsten-tantalum-cobalt grade tools or
  • High-speed tungsten-cobalt or molybdenum-tungsten-vanadium tools
  • Cutting lubricants:
    • Chlorinated, sulfurized  fatty mineral oil
    • Rich emulsion of 10 parts water and 1 part soluble oil
  • Surface and cylindrical grind with wheels:
    • Aluminum oxide
    • Vitrified bond of medium or soft hardness and medium open structure
    • Use 1 pound of sal soda with 25 gallons of water, or chemically active grinding coolant

Weldabiltiy of Inconel™ 713C

  • Inconel 713C can be used in applications using very low restraint
  • Use Inco-Weld A electrode
  • Flash-butt weld
  • Inconel 713C is also good for hydrogen-atmosphere brazing with normal high-heat brazing alloy with electroplated mating surfaces
