Cov Ntawv Thov
Incoloy 800: Rau cov ntawv thov kub siab xws li cov kev hloov cua sov thiab cub hluav taws xob.
Incoloy 825: Rau kev ua qias tuaj, tswj kev ua qias tuaj, thiab thaj chaw thaj chaw uas muaj cov kua qaub yog qhov tseem ceeb.
Thaum Tshav Kub Kub Ua
Tsim rau cov ntawv thov kub siab, Incoloy 800 tuaj yeem tiv taus kub txog 1100 degree. Incoloy 825 tuaj yeem tiv taus ntau qhov kub tab sis yog qhov paub dua rau nws corrosion tsis kam.
Corrosion Kuj
Vim tias Incoloy 825 muaj Molybdenum thiab tooj liab, nws ua tau zoo dua li Incoloy 800 nyob rau ib puag ncig uas muaj txo cov neeg sawv cev xws li sulfuric thiab phosphoric acids.
Tus nqi
Incoloy 825 feem ntau kim heev vim tias nws cov ntsiab lus corrosion tsis kam thiab alloying ntxiv. Incoloy 800 yog tus nqi ntau hauv qhov kub thiab txias tab sis muaj cov mob corrosive.
Cov Qauv Tseem Ceeb
Incoloy 800: ASTM B409, ASTM B407
Incoloy 825: ASTM B424, ASTM B425
Ua Thiab Weldability
Ob lub alloys muaj kev ua haujlwm zoo thiab kev siv tshuaj tiv thaiv kab mob 825, kev saib xyuas yuav tsum yog kom tsis txhob muaj paug rau thaum lub ntsej muag, raws li nws corrosion tsis kam nyob ntawm kev coj dawb huv ntawm cov alloy.
Qhov twg yog qhov zoo dua? Incoloy 800 vs. 825 alloy
Qhov kev xaiv ntawm Incoloy 800 thiab 825 nyob ntawm koj daim ntawv thov xav tau:
Rau qhov siab kub, txheej txheem kev ntseeg-tseem ceeb, xaiv Progoy 800.
Nyob rau hauv ib puag ncig nrog corrosive tawm, tshwj xeeb tshaj yog acidic xov, xaiv Prololoy 825.
