Dab tsi yog cov yam ntxwv ntawm 926 incoloy -} kev paub

1. Cov yam ntxwv ntawm Incoloy 926 yog dab tsi?

Incoloy 926 (tsis yog N08926) yog aSuper Austenitic Stainless HlauRenowned rau nws qhov tshwj xeeb corrosion tsis kam thiab tshuab kev ruaj khov nyob hauv ib puag ncig hnyav. Nws cov yam ntxwv tseem ceeb muaj xws li:

Ntsej Muag Corrosion Kuj: Nws ua kom pom cov khoom tawg, thiab kev nyuaj siab corrosion (SCC) thiab acidic acid, phosphoric acid). Qhov no feem ntau yog vim nws siab Molybdenum (MO: 6.0-7.0%) thiab nitrogen (n:

Cov Khoom Siv Zoo Tshaj Plaws: Nws tswj hwm lub zog zoo tensile muaj zog, tuaj yeem tawm tsam ntau qhov kub (los ntawm cryogenic rau siab kub ib ncig ntawm 500 degree). Nws tseem muaj kev qaug zog tiv, ua rau nws haum rau cov ntawv thov cov ntaub ntawv.

Zoo txiav: Txawm tias nws cov ntsiab lus siab siab, nws tuaj yeem ua tiav ntawm cov qauv qauv xws li ua haujlwm txias (dov, kev zam txim), kub ua haujlwm, thiab vuam. Cov ntawv kom raug - Weld Kev Kho Mob Kub (piv txwv li kev daws teeb meem sai sai) yog pom zoo kom rov qab ua rau corrosion tsis kam thiab homogene tshuab.

Siab tiv taus oxidation: Nws tiv thaiv oxidation nyob rau hauv me ntsis tos kub, ua tsaug rau nws cov chromium (CR:

2.What yog lub zog tensile ntawm incoloy 926?

Lub zog tensile ntawm Incoloy 926 yog txhais tias yog qhov kev ntxhov siab tshaj plaws uas cov khoom tuaj yeem tiv thaiv ua ntej deformation kev puas tsuaj lossis tawg. Nws lub zog tensile muaj zog tseem ceeb (ib astm A240 / A240M thiab EN 10088-1 Cov Qauv) yog:

Chav nyob kub (20 degree): Tsawg kawg650 MPa(94,300 psi); Cov nqi raug ntau los ntawm 680-750 MPa (98,600-108,800 psi).

Kom kub siab: Tensile lub zog txo qis nce qib nrog kev nce kub. Piv txwv li:

Ntawm 300 degree: ~ 580 MPa (84,100 PSI)

Ntawm 400 degree: ~ 520 mpa (75,400 psi)

Thaum 500 degree: ~ 460 mpa (66,700 psi)

NCO TSEG: Muaj nuj nqis yuav sib txawv me ntsis raws li kev kho cua sov (piv txwv li cov lus qhia {{{{}} ua haujlwm) thiab cov ntaub tuab.

3. Dab tsi yog cov txiaj ntsig lub zog ntawm Incoloy 926?

Tos lub zog (0.2% offset muab lub zog muaj zog, qhov kev ntxhov siab ntawm 0.2% kev ruaj ntseg zoo li cas) yog qhov ntsuas qhov tseem ceeb rau tsim cov khoom lag luam. Incoloy 926's cov txiaj ntsig zoo tawm lub zog tseem ceeb (ib astm thiab en cov qauv) yog:

Chav nyob kub (20 degree): Tsawg kawg300 mpa(43,500 psi); Cov nqe lus raug ntau los ntawm 320-380 MPa (46,400-55,100 psi).

Kom kub siab: Zoo ib yam li tensile lub zog, tawm los lub zog tsis lees txais kev kub. Piv txwv li:

Ntawm 300 degree: ~ 270 MPa (39,200 psi)

Ntawm 400 degree: ~ 24 MPa (34,800 psi)

Ntawm 500 degree: ~ 210 MPa (30,500 psi)

NCO TSEG: Ua haujlwm txias tuaj yeem ua kom muaj zog ntxiv (piv txwv li, tab sis qhov no yuav txo tau lub zog rau corrosion - tseem ceeb siv.
