Molybdenum Alloy 263 Steel Flat Bar
Nimonic Alloy 263 is an age-hardenable nickel - cobalt - chromium - molybdenum alloy designed to provide excellent fabrication properties in the annealed condition, but also has very good aging strength properties. Alloy 263 is easier to form or weld than other materials such as Waspaloy or Rene 41 and exhibits excellent intermediate temperature ductility. Alloy 263 is supplied in the annealed condition and has excellent ductility under these conditions, making it suitable for cold forming and hot working. Alloy 263 can be welded using a matched combination of filler wires in both TIG and MIG form.
