Nickel Alloy 690 kuj pom zoo txhua yam muaj zog thiab kub-kub stability. Nws tuaj yeem tswj hwm nws cov qauv kev ncaj ncees thiab kev ua tau zoo txawm tias qhov kub siab, uas yog qhov tseem ceeb hauv kev siv xws li roj turbines thiab cov khoom siv hluav taws xob. Lub peev xwm los tiv thaiv creep thiab kev ntxhov siab ntawm qhov kub thiab txias ua rau nws ua haujlwm tau zoo hauv kev xav tau thermal.
Cov muaj pes tsawg leeg ntawm Nickel Alloy 690 feem ntau suav nrog ib qho tseem ceeb ntawm npib tsib xee, nrog rau chromium thiab lwm yam alloying ntsiab. Cov ntsiab lus chromium pab txhawb rau nws txoj kev tiv thaiv corrosion los ntawm kev tsim cov txheej txheem oxide passive rau ntawm qhov chaw. Cov txheej no ua raws li kev tiv thaiv kev tiv thaiv, tiv thaiv ntxiv oxidation thiab corrosion.
Hauv kev lag luam hluav taws xob nuclear, Nickel Alloy 690 yog siv rau hauv lub tshuab hluav taws xob lub tshuab hluav taws xob vim nws tsis kam ua rau kev ntxhov siab corrosion tawg thiab intergranular nres. Nws pab kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov tshuab hluav taws xob nuclear los ntawm kev tiv thaiv cov xwm txheej hnyav hauv lub tshuab tsim hluav taws xob.
Zuag qhia tag nrho, Nickel Alloy 690 UNS N06690 yog cov khoom siv ntau yam thiab txhim khu kev qha uas muaj kev sib xyaw ua ke ntawm kev tiv thaiv corrosion, txhua yam muaj zog, thiab qhov kub thiab txias. Nws cov khoom tshwj xeeb ua rau nws yog qhov kev xaiv tseem ceeb rau ntau daim ntawv thov tseem ceeb uas qhov ua tau ntev thiab kev ua tau zoo yog qhov tseem ceeb tshaj plaws.
