Dab tsi yog inconel 725 sib npaug rau -} kev paub

1. Dab tsi yog inconel 725 sib npaug rau?

Inconel 725 (Tsis yog N07725) yog npib tsib xee {} chromium alloy- molybdenum- molybdenum- Nws cov ntaub ntawv sib npaug yog qhov tshwjxeeb tshwj xeeb, raws li nws yog ib qho nag lossis daus - Cov cim tsis muaj txiaj ntsig thiab cov yam ntxwv ua tau zoo. Qhov tseem ceeb sib npaug suav nrog:

ASTM B637: Thawj cov qauv astm qauv rau inconel 725 nyob rau hauv daim ntawv ntawm seamless hlab, txhais nws cov tshuaj lom neeg, thiab tsim khoom.

ASME SB-637: Tus asme (Asmeskas haiv neeg ntawm cov kws kho tshuab engineers) counterpart rau Astm B637, siv rau cov khoom siv hauv cov hlab ntsha thiab cov ntawv thov boiler.

ISO 15156-3: Tus qauv uas cais tawm tswv yim 725 Raws li cov khoom haum tsim nyog rau cov roj thiab roj downhole cov khoom siv, ua raws li nws txoj hlab corrosion (sib dhos nrog nws cov khoom noj qab zib (h}}} muaj) ib puag ncig.

Lwm Cov Kev: Tsis muaj qhov ncaj qha "hom kev sib npaug" (piv txwv li, tsis muaj tseeb phim rau ib qho kev sib tw zoo li 316 stainless cov qib lossis qib inconel zoo li 625). Txawm li cas los xij, nws qee zaum piv rauHastelloy C-276Nyob rau hauv cov nqe lus ntawm corrosion tsis kam, txawm haastelloy c-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} agents-hardenable thiab muaj lub zog sib txawv-muaj lub zog sib txawv.

2. Dab tsi yog lub tensile lub zog ntawm inconel 725?

Lub zog tensile ntawm inconel 725 yog qhov siab heev rau nwsKev Kho Cua Sov, raws li nws yog ib qho nag lossis daus - Cov khoom siv tsis yooj yim (muaj zog ntawm kev siv kev laus). Hauv qab no yog cov txiaj ntsig raug zog tensile ib tus qauv kev lag luam (piv txwv li, Astm B637, ASME SB {637) rau cov mob tshav kub:

Kev Kho Cua Sov	Tensile lub zog (yam tsawg kawg nkaus)	Tensile lub zog (raug)	Tawm Zog (0.2% offset, tsawg kawg nkaus)
Daws annealed (sa)	~ {860 mpa mpa (125,000 psi)	~ 900 mpa (130,500 psi)	~ 485 MPa (70,300 PSI)
Nag lossis aged (laus, piv txwv li, 732-760℃/ 1350-1400℃f rau 8 teev)	~ 1170 MPa (170,000 PSI)	~ 1240 MPa (180,000 PSI)	~ 1035 MPa (150,000 PSI)

Nco tseg: Cov txiaj ntsig no yuav sib txawv me ntsis raws li daim ntawv foos (piv txwv li, raj, bar, xaim lag luam.

3. Dab tsi yog qhov hardness ntawm inconel 725?

Zoo li lub zog tensile, lub hardness ntawm inconel 725 yog qhov muaj zog los ntawm nws txoj kev kho cua sov. Cov nplai ntau tshaj plaws uas siv rau qhov no alloy yogRockwell C (HRC)thiabBrinell (HBW)Cov. Lub hardness nruj yog li hauv qab no:

Kev Kho Cua Sov	Rockwell C (HRC, raug)	Brinell hardness (HBW, raug)
Daws annealed (sa)	20-25 hrc	200-230 hbw
Nag lossis daus tawv (hnub nyoog)	35-40 hrc	340-380 HBW

Kev ntsuas Hardness feem ntau ua kom paub tseeb qhov ua tau zoo ntawm kev ua haujlwm laus, ntau dua hardness ncaj qha, nag lossis daus {{0} {tawv microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructening microstructen Raws li nrog tensile lub zog, kev hloov pauv me me yuav tshwm sim raws li daim ntawv foos thiab kev ua.
