Refractaloy 26 yog Fe - NI - Co - Cr nag lossis daus hardening hom deformation ntawm kub kub alloy, ntev siv C - 570 ℃ kub ntau ntawm 540 ℃, qhov kub siab tshaj tuaj yeem ncav cuag 677 C, ntxiv cov khoom ntawm Cr, mo alloy. Cov tshuaj muaj zog ntxiv, siab mus rau qis titanium, aluminium daim ntawv y aging ntxiv dag zog rau theem, thaum drilling cov ntsiab lus ua los ntawm titanium, aluminium solubility nyob rau hauv cov khoom tov yog txo, prompted y theem nag lossis daus tus nqi nce, thiaj li los txhim kho thermal stability ntawm y, txo. y' theem ntawm stacking txhaum zog.
Cov khoom sib xyaw ntawm cov alloy yog superior, nrog zoo heev tensile kuj, quab yuam so thiab creep tsis kam, tsis muaj notch rhiab heev.

Cov hlau tau siv rau hauv kev tsim cov av chav turbine enclosure, nyob rau hauv lub chav ua haujlwm ntawm 540 ℃ ~ 570 ℃ tuaj yeem ua haujlwm rau ntau tshaj 100,000 xuab moos, kev siv tau zoo. Zoo sib xws alloys siv txawv teb chaws los ua aero turbine cav complex qhov chaw. thiab cov hniav Cov hlau muaj cov yas zoo ntawm qhov nruab nrab kub, uas tuaj yeem txo qhov tawg ntawm qhov chaw vim kev ua haujlwm ntev thiab nkag mus rau hauv lub sijhawm siv ntev. qhov kub thiab txias
