Khoom Taw Qhia

Inconel 725 yog tsim tshwj xeeb rau cov roj acidic thiab roj av thiab cov ntawv thov kev lag luam hauv hiav txwv uas muaj H₂S, CO₂, thiab chlorides. Nws boasts ultra-siab zog thiab sab saum toj-tier corrosion kuj, tshwj xeeb tshaj yog zoo heev tiv thaiv kev nyuaj siab corrosion cracking (SCC). Nws yog qhov zoo tagnrho rau cov ntawv thov feem ntau xav tau ob qho tib si siab zog thiab corrosion kuj.

Cov qauv zoo sib xws rau Inconel 725 nickel alloy nplooj ntawv peb muab yog tuav: ASTM B564, AMS 5924; kub-rolled bars/tubes: ASTM B865/B805. Tau kawg, peb kuj muab lwm cov ntaub ntawv, xws li alloy 725 nplooj ntawv, raj, strips (coils), thiab cov xov hlau, uas tuaj yeem ua raws li cov kev cai tshwj xeeb. Thovtiv tauj pebrau ib daim ntawv qhia tshwj xeeb los yog nqe lus.

Phau Ntawv Qhia Txog Kev Ua Lag Luam

1. Kev xaiv tus neeg muag khoom:Qhov no yog ib nrab ntawm kev sib ntaus sib tua hauv kev ua tiav kev yuav khoom. Nws yog ib qho tseem ceeb los xaiv ib lub chaw tsim khoom lossis sab saum toj -tier distributor nrog lub peev xwm ntawm dual- txheej txheem tsim khoom ntawm lub tshuab nqus tsev induction melting (VIM) thiab electroslag remelting (ESR) / nqus arc remelting (VAR). Lawv cov ntaub ntawv teev tseg nyob rau hauv siab -kev ua tau zoo nickel-raws li alloys (xws li 718 thiab 625) yuav tsum tau ua tib zoo tshuaj xyuas.

2. Tej yam tseem ceeb ntawm kev nug thiab daim ntawv cog lus:Thaum nug txog tus nqi, tsis txhob nug "Yuav ua li cas yog lub phaj 725?" Koj yuav tsum muab:

Inconel 725 qib thiab tus qauv, cov lus qhia meej, lub xeev kev kho cua sov (xws li, kev kho cov tshuaj + kev laus), kom muaj nuj nqis, hnub xa khoom, thiab cov ntaub ntawv xeem yuav tsum tau (xws li, MTC + thib peb- tog UT cov ntaub ntawv).

3. Tus nqi thiab kev xa khoom xav tau:Vim yog tus nqi siab ntawm cov hlau alloy thiab cov txheej txheem nyuaj, tus nqi siab heev, thiab lub voj voog ntau lawm tuaj yeem kav ntev li ob peb lub hlis. Tsawg- nqe ntxiab muaj kev pheej hmoo siab thiab tuaj yeem ua raws li cov khoom tsis yog - qauv, kev kho cua sov yooj yim, lossis cov khoom siv tsis huv.

4. Kev sab laj txog kev hloov hauv tsev:Rau qhov tsis yog -kev ua haujlwm hnyav, koj tuaj yeem sab laj nrog cov neeg muag khoom kom pom tias muaj cov khoom lag luam hauv tsev uas muaj kev ua haujlwm zoo sib xws thiab tus nqi zoo dua rau kev ntsuam xyuas.

Cov txheej txheem tsim khoom thiab cov kev sib tw

Inconel 725 yog ib qho "nyuaj-rau- cov khoom siv tshuab", uas cuam tshuam ncaj qha rau koj cov nqi ua haujlwm thiab cov txiaj ntsig. Txawm hais tias yuav cov khoom siv raw, machining qhov yooj yim, lossis precision-machined qhov chaw, cov ntsiab lus hauv qab no yuav tsum raug sau tseg los ntawm cov neeg ua haujlwm paub txog kev ua haujlwm theem nrab:

Kub ua haujlwm:Forging thiab dov muaj qhov nqaim qhov kub thiab txias (piv txwv li, 1050-1170 degree) thiab yuav tsum tau tswj nruj; txwv tsis pub, cracking yog yuav.

Vuam:Vuam tuaj yeem ua tau, tab sis cov khoom siv vuam sib xws (xws li ERNiCrMo-3 lossis ERNiCrMo-15) yuav tsum tau siv, nrog rau cov txheej txheem kev siv hluav taws xob tsawg. Cov khoom tseem ceeb yuav tsum tau ua kom tiav cov kev kho mob thiab cov txheej txheem kev laus tom qab vuam kom rov qab kho qhov kev tiv thaiv corrosion thiab SCC tsis kam ntawm thaj chaw muaj kev kub ntxhov.

Machining:Nws lub zog siab, tsis tshua muaj thermal conductivity, thiab kev ua haujlwm- kev sib zog ua kom muaj zog ua rau muaj zog txiav, siab txiav kub, thiab cov cuab yeej siv ceev heev. High-kawg carbide lossis cov cuab yeej ceramic yuav tsum tau siv, siv lub tswv yim ntawm kev ceev qis, siab pub tus nqi, thiab ua kom txias txaus.

Cov ntsiab lus tseem ceeb ntawm kev soj ntsuam zoo

Txhawm rau ua kom cov khoom zoo ntawm Inconel 725 npib tsib xee alloy phaj, daim ntawv qhia thib peb -ib tog yuav tsum tau thov los ntawm tus neeg muag khoom thaum yuav khoom. Lork Inspection Laboratory qhov kev ntsuam xyuas dav dav qhia txog plaub yam tseem ceeb hauv qab no:

1. Cov ntaub ntawv tshuaj xyuas:Cov neeg muab khoom yuav tsum muab daim ntawv pov thawj cov ntaub ntawv tiav, uas yuav tsum muaj xws li: tus naj npawb ntawm cov khoom siv hluav taws xob, cov khoom siv tshuaj lom neeg, cov khoom siv hluav taws xob muaj hnub nyoog, cov ntaub ntawv kho cua sov, thiab tsis yog - daim ntawv qhia txog kev puas tsuaj.

2. Thib peb-Party Verification:Tom qab kev tsim khoom, thib peb- kev sim thib peb (xws li SGS) raug txib los ua cov ntawv pov thawj hauv qab no:

Chemical Composition Verification: Spectroscopic tsom xam.

Mechanical Property Retesting: Tensile and hardness testing.

Tsis yog-Kev kuaj kev puas tsuaj: Ultrasonic kuaj (UT) ntawm daim hlau thiab qhov tseem ceeb blanks los kuaj xyuas qhov tsis xws luag.

Kev Tshuaj Xyuas Metallographic: Tshawb xyuas cov nplej loj thiab microstructure.

3. Kev kuaj tshwj xeeb Corrosion:Rau cov ntawv thov tseem ceeb, kev ntsuam xyuas rau pitting corrosion, crevice corrosion, los yog kev nyuaj siab corrosion cracking yuav tsum tau raws li txoj kev xws li ASTM G48.
