Product Description

R26 is Fe-Ni-Co-Cr-based precipitation hardening deformed superalloy, the long-term use temperature range is 540ºC-570ºC, and the service temperature can reach 677ºC.

The alloy is solid solution strengthened by adding chromium and molybdenum elements, adding high titanium and low aluminum elements to form a γ' aging strengthening phase, and at the same time, the solubility of cobalt elements, titanium and aluminum in solid solution is reduced, which promotes the increase of γ' phase precipitation, thereby increasing the γ' phase.

The thermal stability of the 'phase reduces the stacking fault energy of the γ' phase.

The comprehensive properties of the alloy, with excellent stress relaxation resistance and creep resistance, and no notch sensitivity.

It is suitable for making bolts, seal springs, sealing rings, pins and other parts.

The main products are hot-rolled and forged bars, hot-rolled sheets and cold-rolled sheets.
