Overview

Alloy R26 is Fe – NI – Co – Cr precipitation hardening type deformation of high temperature alloy, long-term use of C – 570 °C temperature range of 540 °C, the highest temperature can reach 677 C, add element of a Cr, mo alloy solid solution strengthening, high to low titanium, aluminum form y aging strengthening phase, while drilling elements made of titanium, aluminum solubility in the solid solution is reduced, prompted y phase precipitation amount increase, so as to improvel the thermal stability of y, reduce y ‘phase of the stacking fault energy. 

 The nickel-based refractory R26  combines excellent creep resistance and good hot chemical properties. Its characteristics make it a preferred candidate for the most difficult applications.
