1. Txheej txheem cej luam ntawm Incoloy 800H (NO8810) nickel-based alloy:
Cov ntsiab lus Cr hauv Incoloy 800H (NO8810) npib tsib xee-raws li alloy feem ntau yog 15-25%, cov ntsiab lus nickel yog 30-45%, thiab nws muaj me me ntawm aluminium thiab titanium. Piv nrog Incoloy 800 alloy, cov ntsiab lus carbon yog tswj los ntawm tsawg dua los yog sib npaug li 0.1% mus rau 0.05-0.1%, uas zoo dua txhim kho lub zog ntawm cov hlau. Cov hlau no muaj cov ntsiab lus siab chromium thiab cov ntsiab lus npib tsib xee txaus, yog li nws muaj qhov kub thiab txias corrosion kuj thiab siv dav hauv kev lag luam. Nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking hauv chloride, tsawg-concentration NaOH aqueous daws thiab high-temperature thiab high-pressure dej, yog li nws yog siv los tsim cov cuab yeej uas tiv taus kev ntxhov siab corrosion cracking. Qhov kev tiv thaiv corrosion zoo dua li ntawm cov hlau tsis muaj austenitic thiab zoo dua li Inconel 600 alloy; nyob rau hauv kev tsim cov khoom siv corrosion-resistant kev ntxhov siab tawg, nws zoo dua Inconel 600 thiab Monel 400 alloy.
2. Daim ntawv thov thaj chaw ntawm Incoloy 800H (NO8810) nickel-based alloy:
Incoloy 800H (NO8810) alloy chemical kev lag luam, nuclear generators, nitric acid coolers, acetic anhydride cracking hlab, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam.
5. Incoloy 800H (NO8810) nickel-raws li alloy siv cov qauv:
1. Incoloy 800H (NO8810) alloy kub dov steel phaj: ASTM B409.
2. Incoloy 800H (NO8810) alloy pas nrig: ASME SB-408.
3. Incoloy 800H (NO8810) alloy steel yeeb nkab: ASME SB-407.
4. Incoloy 800H (NO8810) alloy forgings: ASME SB-564.
3. Incoloy 800H (NO8810) nickel-raws li alloy ua kev ua tau zoo:
1. Incoloy 800H (NO8810) alloy kub ua:
(1) Qhov ntsuas kub yog 1200 degree ~ 950 degree, thiab txoj kev txias yog dej quenching lossis cua txias sai.
(2) Txhawm rau kom tau txais qhov kev ua tau zoo tshaj plaws thiab kev ua haujlwm tsis zoo, kev daws teeb meem yuav tsum tau ua tom qab ua haujlwm thermal.
(3) Cov khoom siv tuaj yeem ncaj qha mus rau hauv lub qhov cub uas tau ua kom sov txog 1200 degree, khaws cia kom sov rau lub sijhawm txaus thiab tom qab ntawd tawm sai sai ntawm lub qhov cub rau kev ua haujlwm thermal nyob rau hauv qhov ntsuas kub. Thaum cov khoom kub poob qis dua qhov kev ua haujlwm thermal, nws yuav tsum tau rov ua dua.
2. Incoloy 800H (NO8810) alloy txias ua:
(1). Qhov kev ua haujlwm hardening yog ntau dua li ntawm austenitic stainless hlau, yog li cov khoom siv yuav tsum tau xaiv. Cov ntaub ntawv txias ua haujlwm yuav tsum nyob rau hauv qhov kev daws teeb meem thaum tshav kub kub kho, thiab qhov nruab nrab annealing yuav tsum tau ua thaum cov khoom txias ua haujlwm loj.
(2) Yog tias qhov kev ua haujlwm txias txias ntau dua 10%, lub workpiece yuav tsum tau txais kev kho mob thib ob.
3. Incoloy 800H (NO8810) alloy vuam txheej txheem:
Haum rau kev siv cov txheej txheem vuam ib txwm siv nrog cov khoom siv tib yam lossis lwm yam hlau, xws li tungsten electrode inert gas shielded vuam, plasma arc vuam, phau ntawv sub-arc vuam, hlau ncej inert roj shielded vuam, melting ncej inert roj shielded vuam, ntawm cov uas pulse arc vuam yog qhov kev xaiv zoo dua. Yog siv phau ntawv arc vuam, nws raug nquahu kom siv (Ar + Nws + H2+CO2) ua cov roj tiv thaiv.
4. Ntau yam, specifications thiab muab cov xwm txheej ntawm Incoloy800H (NO8810) npib tsib xee-raws li alloy:
1. Ntau yam kev faib tawm: Shanghai Longji tuaj yeem tsim ntau yam kev qhia tshwj xeeb ntawm Incoloy800H seamless kav, Incoloy800H steel daim hlau, Incoloy800H puag ncig tuav, Incoloy800H forgings, Incoloy800H flanges, Incoloy800H rings, Incoloy800H welded strips, 800H welded pipes khoom siv.
2. Kev xa khoom raws li txoj cai: Seamless yeeb nkab: khoom tov + acid whitening, ntev tuaj yeem kho; phaj: khoom tov, pickling, trimming; welded yeeb nkab: khoom tov acid whitening + RT% flaw detection, forging: annealing + polishing; Cov tuav yog nyob rau hauv forged thiab dov lub xeev, nto polished los yog polished; strips yog txias dov, tov mos, thiab descaled; cov xaim xaim xaim xaim nyob rau hauv cov tshuaj pickled disk duab los yog ncaj strip zoo, cov khoom tov ncaj strip zoo sib tsoo Xa hauv lub teeb
