Incoloy 800ht: feem ntau siv nyob rau hauv cov kev siv kub siab xws li kev kho cua sov, thiab superheaters hauv kev lag luam hluav taws xob thiab tshuaj lom neeg.
3. Dab tsi yog cov cuab yeej siv tshuab ntawm Incoloy 800, 800H, thiab 800HT Nickel Alloy cov ntawv txheeb?
Teb:
Cov khoom siv me me ntawm cov alloys sib txawv me ntsis vim lawv muaj pes tsawg leeg:
Incoloy 800:
Yield zog: ~ 30 Ksi (205 MPA)
Qhov kawg tensile lub zog: ~ 60 ksi (415 mpa)
Elongation: ~ 30%
Incoloy 800h:
Peple zog: ~ 35 ksi (240 MPA)
Qhov kawg tensile lub zog: ~ 75 ksi (515 MPA)
Elongation: ~ 25%
Incoloy 800ht:
Peple zog: ~ 45 ksi (310 mpa)
Qhov kawg tensile lub zog: ~ 85 ksi (585 mpa)
Elongation: ~ 20%
Cov alloys muaj cov khoom siv zoo uas ua kom lawv tiv thaiv kev ntxhov siab ntau thiab kub tsis muaj qhov tsis txaus ntseeg lossis tsis muaj qhov tsis txaus ntseeg.
4. Dab tsi yog corrosion tsis kam ntawm Incoloy 800, 800H, thiab 800HT cov ntawv txheeb?
Teb:
Cov alloys muab kev tiv thaiv zoo heev rau oxidation, carburization, thiab corrosion ntawm qhov kub:
Incoloy 800: Zoo tsis kam mus rau oxidation thiab carburization txog 1500 ° F (815 ° C). Nws tseem ua yeeb yam zoo hauv kev ua kom muaj zog me me, xws li sulphur-muaj gases.
Incoloy 800H: Txhim kho kom tsis kam rau cov high-kub oxidation thiab carburization, tshwj xeeb hauv kev txo ib puag ncig thiab cov leej faj-muaj roj.
Incoloy 800ht: superior tsis kam rau oxidation thiab carburization ntawm kev siv nyiaj nyob rau hauv thermal reactors thiab furnaces raug cov cua sov siab thiab muaj cov xwm txheej.
5. Dab tsi yog cov cwj luam vuam ntawm incoloy 800, 800H, thiab 800Ht Nickel Alloy Ntawv?
Teb:
Cov alloys feem ntau yooj yim rau weld siv cov qauv txheej txheem zoo li Tig thiab Mig Vuam. Txawm li cas los xij, muaj qee qhov kev txiav txim siab:
Incoloy 800: Zoo heev Veldability nrog cov khoom siv cov khoom siv thiab kev pheej hmoo tsawg kawg ntawm kev tawg. Nws yog feem ntau welded siv aws A5.14 ER800 tus tub lim hlau.
Incoloy 800H: Yuav tsum muaj kev tswj hwm cov ntsiab lus carbon kom tsis txhob muaj kev tsim ntawm carbide precipitates, uas muaj zog cuam tshuam rau nws lub zog kub. Siv cov khoom siv kom zoo (xws li ER308 lossis ER310) yog qhov tseem ceeb.
Incoloy 800ht: vuam yuav tsum tau mloog kom tsis txhob muaj teeb meem nrog cov chaw tiv thaiv kub uas tuaj yeem ua rau nws lub zog. Kev siv ntawm cov khoom siv muaj tseeb (zoo li ER308h) thiab tom qab kev kho cua sov sov yuav tsim nyog rau kev ua tau zoo.
Cov alloys feem ntau siv nyob rau hauv cov kev siv kub siab-qhov uas ntseeg tau, ntev-ntev-ntev ntev yog qhov chaw tsim nyog, thiab cov Welds yuav tsum tuaj yeem tiv thaiv cov mob siab.
