Alloy 825 (UNS N08825) yog austenitic nickel-hlau-chromium alloy nrog ntxiv ntawm molybdenum, tooj liab thiab titanium. Nws tau tsim los muab qhov tshwj xeeb corrosion kuj nyob rau hauv ob qho tib si oxidizing thiab txo ib puag ncig. Lub alloy yog resistant rau chloride kev nyuaj siab-corrosion tawg thiab pitting. Qhov sib ntxiv ntawm titanium stabilizes Alloy 825 tiv thaiv rhiab heev nyob rau hauv lub as-welded mob ua rau cov alloy resistant rau intergranular nres tom qab raug rau kub nyob rau hauv ib tug ntau yam uas yuav sensitize unstabilized stainless hlau.

Weldability
Alloy 825 tuaj yeem ua tau yooj yim welded los ntawm cov txheej txheem hlau thaiv-arc siv alloy vuam electrode 135, cov roj tiv thaiv arc txheej txheem siv alloy muab tub lim hlau 65, thiab cov txheej txheem vuam tsis kam. Lub alloy yuav tsum tsis muaj kev kho cua sov tom qab. Lub corrosion kuj ntawm deposited weld hlau los ntawm ob qho tib si npog electrode thiab liab qab hlau yog sib npaug rau cov niam txiv hlau.
Kev kho cua sov
Incoloy 825 yog stabilize annealed ntawm 940 degree. Cov qauv softest yog tau ntawm 980 degree. Cov ntu hnyav dua li daim ntawv, sawb thiab xaim yuav tsum tau quenched kom tsis txhob rhiab heev.
Corrosion Resistance
Cov cuab yeej zoo tshaj plaws ntawm Incoloy 825 yog nws cov corrosion kuj. Hauv kev txo qis & oxidising tej yam kev mob, Incoloy 825 resists dav corrosion, pitting & crevice corrosion, intergranular corrosion thiab kev nyuaj siab corrosion cracking. Nws yog tshwj xeeb tshaj yog pab tau nyob rau hauv sulfuric & phosphoric acids, sulfur muaj flue gases, qaub roj thiab roj qhov dej thiab dej hiav txwv.
