Yog tias koj ua haujlwm hauv aerospace, marine, tshuaj, lossis roj thiab roj kev lag luam, koj yuav ntsib Inconel 625, npib tsib xee-chromium- molybdenum alloy paub txog nws qhov tshwj xeeb corrosion tsis kam, siab - kub stability, thiab txhua yam muaj zog. Ib lo lus nug uas peb nquag tau txais los ntawm cov neeg siv khoom yog: "Dab tsi yog qhov nyuaj ntawm Inconel 625?"
Nyob rau hauv phau ntawv qhia no, peb yuav piav qhia txog qhov hardness qhov tseem ceeb ntawm Inconel 625, cov yam ntxwv uas cuam tshuam rau nws hardness, yuav ua li cas kuaj nws hardness, thiab vim li cas tus yam ntxwv no tseem ceeb heev rau koj daim ntawv thov tshwj xeeb.
Vim li cas Hardness tseem ceeb rau koj qhov project?
Machinability: Cov khoom siv tawv tuaj yeem ua rau cov cuab yeej hnav thiab cov nqi machining. Kev nkag siab txog qhov hardness pab xaiv cov cuab yeej txiav txoj cai thiab qhov ntsuas.
Hnav Resistance: Cheebtsam raug kev sib txhuam los yog cuam tshuam tau txais txiaj ntsig los ntawm hardness siab dua.
Structureal Integrity: Xyuas kom meej tias cov khoom muaj lub zog ntawm cov neeg kho tshuab thaum muaj kev ntxhov siab, kub siab, lossis ib puag ncig corrosive.
Inconel 625 Hardness
Inconel 625 yog anpib tsib xee-chromium- molybdenum alloyntxiv dag zog rau feem ntau los ntawm kev daws teeb meem es tsis yog nag lossis daus hardening. Nws qhov hardness txawv me ntsis nyob ntawm daim ntawv (phaj, ntawv, bar, lossis yeeb nkab) thiab kev kho cua sov, tab sis tus nqi raug raws li hauv qab no:
| Daim ntawv / Cov xwm txheej | Hardness (HRB / HRC / HV) |
|---|---|
| Annealed / Raws li -Fabricated | 95-100 HRB (~ 20 HRC, 200-220 HV) |
| Ua haujlwm txias / Ua haujlwm hnyav | 25-35 HRC (~ 250-350 HV) |
| Kev kho mob | 22-28 HRC (~ 230-280 HV) |
Qhov tsawg kawg nkaus hardness ntawm Inconel 625 yog dab tsi?
Yam tsawg kawg nkaus hardness rau annealed Inconel 625 feem ntau yog 190 HBW (200 HV lossis 85 HRB), raws li ASTM B446 tus qauv.
Dab tsi yog qhov ceev ntawm Inconel 625?
Qhov ceev ntawm Inconel 625 feem ntau yog teev raws li 8.44 g / cm³ (grams ib cubic centimeter) los yog 0.305 lb/in³ (pounds ib cubic inch), uas yog ib qho tseem ceeb ntawm lub cev ntawm no high -kev ua tau zoo nickel-chromium alloy.
Tej yam uas cuam tshuam rau Inconel 625's Hardness
Kev nkag siab txog dab tsi cuam tshuam rau Inconel 625 lub hardness pab koj xaiv cov khoom siv zoo thiab zam cov teeb meem kev ua haujlwm. Nov yog 3 yam tseem ceeb tshaj plaws:
Inconel 625 Cov txheej txheem kho cua sov
Inconel 625 feem ntau yog muab tso rau hauv qhov mob annealed (rhuab mus rau 1100-1150 degree, ces txias sai), uas optimizes ductility thiab corrosion kuj thaum tuav lub hardness nruab nrab. Rau cov ntawv thov uas yuav tsum tau muaj zog dua (piv txwv li, hnav- cov khoom tiv thaiv), nag lossis daus hardening (kev laus ntawm 700-800℃rau 2-8 teev) nce hardness los ntawm kev tsim cov theem intermetallic (" thiab '), yam tsis muaj kev cuam tshuam corrosion ntau dhau.
Inconel 625 Kev Ua Haujlwm Txias
Kev ua haujlwm txias (xws li dov, kos duab, thiab khoov) ua rau kom muaj zog ntawm Inconel 625 alloy los ntawm kev qhia txog kev txav mus rau hauv cov qauv hlau. Piv txwv li, txias- ua haujlwm Inconel 625 tubing tuaj yeem ua tiav qhov tawv ntawm 250-280 HV, ua rau nws zoo tagnrho rau cov ntawv thov siab.
Cov ntsiab lus impurity
Inconel 625 cov tshuaj muaj pes tsawg leeg yog nruj tswj hwm (Ni: 58% min, Cr: 20-23%, Mo: 8-10%, Nb + Ta: 3.15-4.15%). Cov kab tsis huv (piv txwv li, carbon, sulfur) tuaj yeem hloov kho qhov nyuaj me ntsis-piv txwv li, cov ntsiab lus carbon ntau dua tuaj yeem ua kom tawv tawv tab sis txo qhov weldability. Ib txwm xaiv cov neeg xa khoom uas ua raws li ASTM lossis ASME cov qauv rau kev tswj hwm kev sib xyaw.
Inconel 625 puas tuaj yeem ua kom tawv ntxiv?
Yog lawm, kev kho cua sov ( nag lossis daus hardening ) lossis ua haujlwm txias tuaj yeem ua rau nws cov tawv tawv. Txawm li cas los xij, ntau dhau hardening tuaj yeem txo ductility thiab corrosion kuj.
Inconel 625 nyuaj dua 316 stainless hlau?
Yog lawm. Annealed Inconel 625 (190–220 HBW) yog ib qho nyuaj tshaj annealed 316 stainless hlau (150–180 HBW), ua tsaug rau nws cov nickel ntau dua, molybdenum, thiab niobium cov ntsiab lus.
