AMS 5581 Inconel 625 Nickel Alloy
Khoom Taw Qhia
Inconel 625 (UNS N06625; W.Nr. 2.4856; Alloy 625) yog npib tsib xee-chromium-molybdenum-raws li khoom- daws- muaj zog alloy, tshwj xeeb yog tsim los ua seamless tubing rau {10} kub exchangers. AMS 5581 ua raws li tus qauv specification rau seamless thiab welded tubing ua los ntawm Alloy 625.
Plaub tus yam ntxwv tseem ceeb hauv qab no piav qhia meej vim li cas Inconel 625 tseem nyuaj heev -txawm tias tsis muaj kev kho cua sov.
1. Niobium (3.15–4.15%) - Alloy 625's "Signature Weapon"
Cov ntsiab lus niobium hauv Alloy 625 ua haujlwm raws li nws qhov tshwj xeeb "tus cim cim." Yog tsis muaj niobium, cov hlau yog tsim los ua Alloy 600; nrog niobium, nws dhau los ua Alloy 625- qhov sib txawv uas ua rau muaj qhov sib txawv loj hauv lub zog. Tseem ceeb heev, tsis zoo li Alloy 718- uas yuav tsum tau muaj kev kho mob tom qab vuam-Alloy 625 tshem tawm cov txheej txheem ntxiv no.
2. Molybdenum (8–10%) - Tus "Primary Defender" Tawm tsam Chloride Ions
3. Siab -Kev Ua Haujlwm Kub Kub - Kev Pabcuam Txog 980 degree
Kev Xaiv Cov Khoom Siv Logic: Yog tias qhov ntsuas kub ua haujlwm siab tshaj 650℃thiab vuam yuav tsum, xaiv Alloy 625; Yog tias qhov ntsuas kub qis dua 650℃thiab lub zog siab dua yog qhov tseem ceeb, xaiv Alloy 718; rau ib puag ncig uas muaj cov ntshiab hydrochloric acid, xaiv Alloy C-276.
4. Dav -Spectrum Corrosion Resistance
(Inorganic Acids: Resistant nitric acid, phosphoric acid, sulfuric acid, thiab hydrochloric acid)
(Chloride Ib puag ncig: Tiv thaiv pitting corrosion, crevice corrosion, thiab kev nyuaj siab corrosion cracking)
(NACE MR0175 Certification: Haum rau siv nyob rau hauv qaub roj thiab roj ib puag ncig)
Ib qho yooj yim overlooked point:Tom qab lub sij hawm ntev raug nyob rau hauv lub 550-700℃ntau yam, Inconel 625 undergoes cov nag lossis daus ntawm me me carbides thiab intermetallic theem, uas ua rau ib tug me ntsis txo nyob rau hauv ductility. Yog tias koj qhov kev ua haujlwm tshwj xeeb xav tau kev ua haujlwm siab thiab xav tau ntev - kev pabcuam hauv qhov kub thiab txias, cov khoom siv no yuav tsis yog qhov kev xaiv zoo tshaj plaws. Tej zaum koj yuav xav tau cov lus pom zoo rau lwm cov ntaub ntawv; thov koj xav tiv tauj peb yog tias koj txaus siab.
Machining thiab Vuam
Npaj rau kev siv tam sim ntawd tom qab vuam -qhov no yog lub ntsiab muag ntawm Inconel 625; Nws yog qhov sib cav tias yog ib qho ntawm cov hassle tshaj plaws - npib tsib xee dawb -raws li alloys rau vuam.
1. Vuam-Tsis muaj ntawv tshaj tawm- Kev kho cua sov yuav tsum tau
Qhov zoo tshaj plaws ntawm vuam Alloy 625 yog nws txoj kev yooj yim. Txawm hais tias tom qab-weld kev kho cua sov qee zaus yuav tsum tau kho kom zoo dua qub, nws yog qhov xav tau tsawg dua li cov txheej txheem rau Alloy 718, uas yog qhov yuav tsum tau ua kom rov qab kho dua - kev laus. Qhov no yog qhov yooj yim heev rau peb cov neeg siv khoom koom nrog hauv - cov kav dej loj.
2. Ua haujlwm txias- Qhia txog kev ua haujlwm tseem ceeb; intermediate annealing yog yuav tsum tau.
3. Kub ua haujlwm- Nta lub qhov rais nqaim ua haujlwm kub; Kev tswj qhov kub thiab txias yog qhov tseem ceeb.
4. Kev kho cua sov- Kev daws teeb meem yog cov txheej txheem tseem ceeb.
5. Machining- Lub xeev annealed yog ib qho yooj yim rau tshuab, whereas lub xeev hardened ua rau cov cuab yeej hnav sai.
6. Kev kho deg- Pickling (siv HNO₃ + HF) yog siv los tshem tawm nplai; corrosion kuj yog maximized tom qab passivation.
