At Amardeep Steel Centre, we provide Nimonic alloy 263, which is a nickel-cobalt-chrome-molybdenum
alloy known for its age-hardening capabilities. This alloy was specifically designed to exhibit
excellent fabrication characteristics in the annealed condition while maintaining strong strength
properties after aging. Compared to materials like Waspaloy or Rene 41, Nimonic 263 is easier to
form and weld, and it demonstrates exceptional ductility at intermediate temperatures.
Our Nimonic 263 is supplied in the annealed condition, offering excellent ductility that makes it
suitable for both cold forming and hot working processes. When it comes to welding Nimonic 263, we
recommend using filler wire with a matching composition in both TIG and MIG forms to ensure optimal
results.
To achieve the desired properties and performance of Nimonic 263, we suggest the following heat
treatments:
