1. Tshuaj muaj pes tsawg leeg
Inconel 600 yog npib tsib xee-raws li kev daws teeb meem ntxiv dag zog siab - kub alloy, belongs rau Ni-Cr-Fe alloy series. Nws cov tshuaj muaj pes tsawg leeg (qhov hnyav feem pua) feem ntau yog nyob rau hauv ntau yam hauv qab no:
- Ni: Ntau dua lossis sib npaug li 72%
- Cr: 14.0 ~ 17.0%
- Fe: 6.0 ~ 10.0%
- Lwm tus: C Tsawg dua lossis sib npaug rau 0.15%, Mn Tsawg dua lossis sib npaug rau 1.0%, Si Less dua lossis sib npaug rau 0.5%, S Tsawg dua lossis sib npaug 0.015%
Cov hlau feem ntau muab qhov zoo tshaj plaws corrosion- tiv taus lub hauv paus los ntawm cov ntsiab lus siab nickel, chromium txhim kho oxidation kuj thiab corrosion kuj; thiab hlau optimizes kev ua tau zoo thiab tus nqi sib npaug. Nws cov tshuaj muaj pes tsawg leeg ua raws li cov qauv thoob ntiaj teb xws li ASTM B166 thiab ASME SB-166.
2. Sib piv nrog rau lwm qib
-Inconel 600 yog ib tug npib tsib xee-chromium- hlau-raws li cov khoom siv ntxiv zog alloy (Ni Ntau dua lossis sib npaug rau 72%, Cr 14-17%, Fe 6-10%). Nws qhov kev ua tau zoo nyob ntawm qhov sib npaug ntawm qhov kev tiv thaiv corrosion ntawm high nickel puag thiab oxidation kuj ntawm chromium hlau, thiab yog haum rau nruab nrab thiab siab kub corrosion ib puag ncig.
-Inconel 625 yog ib qho siab -molybdenum-niobium cov kua muaj zog nickel-raws li alloy (Ni≈58%, Cr 20-}23%, Mo 8-10%, Nb 3.15-4.15%), uas tuaj yeem txhim kho kev kho mob hauv zos thiab tsis muaj corrosion (p) vuam.
-Inconel 718 yog nag lossis daus-nickel hardened nickel-raws li alloy nrog chav tsev kub tensile zog txog li 1275 MPa, uas yog 2.3 npaug ntawm 600. Qhov kev txhawb zog no tso cai rau 718 kom tswj tau 80% ntawm chav tsev kub txog li 650℃ntawm 20, thaum qhov kub thiab txias ntawm qhov muaj zog ntawm 650℃2. Lawv yog qhov kev xaiv zoo tshaj plaws rau qhov kub thiab txias thiab lub zog siab, thiab tsis tuaj yeem hloov pauv hauv aerospace thiab tob{13}}sea engineering.
3. Kev tshuaj xyuas cov yam ntxwv tseem ceeb
-Kev tiv thaiv corrosion
- Muaj zog oxidizing ib puag ncig: Kev ua tau zoo nyob rau hauv siab - kub gases uas muaj chlorine, fluorine, thiab sulfur, thiab tsis kam mus rau boiling sulfuric acid, hydrochloric acid, thiab hydrofluoric acid corrosion nrog ib tug concentration ntawm tsawg dua los yog sib npaug li 50%.
- Intergranular corrosion kuj: Los ntawm kev tswj cov ntsiab lus carbon (tsawg dua lossis sib npaug li 0.15%) thiab cov txheej txheem kho cua sov, chromium- thaj chaw tsis zoo tshwm sim los ntawm nag lossis daus ntawm chromium carbide ntawm thaj tsam lis yog zam, ua tau raws li cov cai ntawm ASTM A262 intergranular corrosion test.
- Kev ntxhov siab corrosion cracking tsis kam: Lub peev xwm los tiv thaiv chloride ion kev nyuaj siab corrosion nyob rau hauv siab -kub thiab siab - dej siab yog zoo dua li ntawm austenitic stainless hlau (xws li 304/316).
-High kub mechanical zog
- Kev khiav hauj lwm kub: -253℃txog 1093 degree; Qhov siab tshaj plaws luv luv oxidation kuj kub tuaj yeem ncav cuag 1177 degree.
- Chav ntsuas kub txhua yam khoom (lub xeev annealed):
- Tensile zog: Ntau dua los yog sib npaug rau 550 MPa
- Yield zog (0.2% offset): Ntau dua los yog sib npaug rau 240 MPa
- Elongation: Ntau dua lossis sib npaug li 30%
- Kev kub siab lub zog tuav: Ntawm 650 degree, lub zog tensile tseem nyob ntawm txog 450 MPa, uas yog tsim rau scenes nrog ntev - lub sij hawm siab - kub loads.
-Kev ua haujlwm thiab vuam kev ua haujlwm
- Kub ua: Forging / dov kub ntau yam yog 980 ~ 1200 degree, thiab nws yog ib qho tsim nyog yuav tsum tsis txhob nyob hauv thaj tsam ntawm 480 ~ 870℃rau lub sijhawm ntev (kom tiv thaiv σ theem nag lossis daus).
- Kev ua haujlwm txias: Nws tuaj yeem tsim los ntawm txias dov, spinning, thiab lwm yam txheej txheem, nrog rau nruab nrab ua haujlwm hardening tus nqi, thiab yuav tsum tau intermediate annealing (1090 ~ 1150℃dej txias) kom tshem tawm kev ntxhov siab.
- Vuam: Haum rau GTAW (TIG), GMAW (MIG), thiab electron beam vuam. ERNiCr-3 (vuam hlau) lossis ENiCrFe-3 (vuam pas nrig) raug pom zoo ua cov khoom siv vuam. Tsis tas yuav tsum tau preheating ua ntej vuam. Annealing tuaj yeem ua tau tom qab vuam kom ua tau zoo raws li qhov xav tau.

Cov ntsiab lus
Inconel 600 tau dhau los ua cov khoom tseem ceeb hauv aerospace, tshuaj, nuclear zog, thiab lwm yam kev lag luam vim nws cov nickel siab -raws li corrosion kuj platform thiab sib npaug kev ua tau zoo nyob rau hauv nruab nrab kub ntau yam. Nws cov txiaj ntsig tseem ceeb nyob rau hauv kev muab kev ntseeg tau zoo dua li cov hlau tsis muaj steel nyob rau hauv thaj tsam ntawm qhov nruab nrab corrosion siv thiab kub, thaum muaj nqi ntau dua thiab ua tau zoo dua li cov khoom sib xyaw ua ke (xws li 625, 718).
