Hastelloy X yog dab tsi?

Nyob rau hauv lub realm ntawm cov ntaub ntawv siab dua engineering, uas cov khoom siv sib luag, thiab kev ua pov thawj txhua hnub, ob peb tus thawj coj ntawm cov khoom lag luam zoo nkauj ntawm kev thawb cov ciaj ciam ntawm thev naus laus zis. Hastelloy x tsis yog lwm yam alloy; Nws yog qhov ua kom zoo nkauj me me ua kom zoo nkauj nickel- chromium {}}}}} molybdenum superalally uas feem ntau hlau tsis muaj.

Hastelloy X tshuaj lom neeg muaj pes tsawg leeg

Hastelloy X (unstr n06002 / w.nr . 2.4665}}}}}}} bued supallots. Nws cov teeb meem tshwj xeeb ntawm cov qia los ntawm kev ua tib zoo ntaus tshuaj lom neeg:

• Nickel (NI): Ua cov hauv paus (kwv yees . 47% min), muab cov inherent corrosion tsis kam, siab}} lub zog kub, thiab muaj zog.
• Chromium (CR): (kwv yees} 0}}%) Qhov tseem ceeb rau kev ua kom muaj kev tiv thaiv cov roj ntsha oxide (CR2O3) nplai. Kuj txhim kho kom tsis kam rau sulfidation thiab qee lub aqogenive corrosives.
• Molybdenum (MO): (kwv yees} 0}}%) ib qho kev daws teeb meem zoo dua - kub lub zog thiab cov plaw ua haujlwm. Kuj txhim kho kom tiv thaiv kom txo cov kua qaub thiab cov qauv hauv nroog zoo li pitting.
• Hlau (FE): (kwv yees} 0}}%) feem ntau tus nqi}- kev tswj hwm tus qauv Austenic thiab pab txhawb kev ua kom tag nrho.
• Cobalt (CO): (0.5 - 2.5%) Txhim kho kom muaj zog thiab hloov kho carbide rau kev txhim kho kom zoo dua qub.
• Tungsten (w): (0.2-}}}}}}}}}}}}}}}}}}}}}}}}}) Ntxiv rau kev daws teeb meem kom muaj zog, tshwj xeeb rau cov creep kam.
• Cov pa roj carbon (c): (0.05-0.15%) Cov qauv carbides (feem ntau M23C6 thiab M6C) uas ntxiv dag zog ntawm cov kev kub ntxhov ntawm cov chaw kub, qhov tseem ceeb rau cov enpees. Kev tswj yog qhov tseem ceeb heev los tiv thaiv carbide ntau dhau kev cuam tshuam nyuaj lossis weldability.

Hastelloy X cov khoom

Hastelloy X tau txhais los ntawm nws qhov zoo kawg ntawm cov khoom, ua rau nws tsis tseem ceeb hauv cov ntawv thov tseem ceeb:

Tshwj xeeb siab - kub lub zog thiab nkag dag zog rau qhov kub tshaj 1200℃(2200℃(2200℃f). Qhov no yog qhov tseem ceeb rau cov khoom siv hauv qab cov neeg kho tshuab thauj hauv cov ntu kub.

Oxidation zoo tshaj: Ua ib qho kev tiv thaiv zoo, tawm tsam chromia nplai, tawm tsam hauv huab cua thiab commusion off urmospheres txog li 1200℃(2200℃f). Qhov tseem ceeb Outperforms txheem txheem stainless hlau thiab ntau lwm cov nickel alloys hauv cov kev tswj hwm no.

Kev tiv thaiv zoo heev rau kev txo cov sulfidation: ua tau zoo nyob rau hauv ib puag ncig muaj sulphur - cov txiaj ntsig kub, ib qho kev sib tw hauv cov txheej txheem combusionion.

Zoo li kev saib xyuas: thaum xav tau kev saib xyuas ntau dua li cov hlau tsis muaj zog, machinyned siv cov txuj ci kub thiab ua kom zoo nkauj ® 242 ™ lossis Hastelloy® W). Annealing yog ib txwm ua ntawm 1175℃(2150℃f) ua raws los ntawm kev ua kom txias sai.

Dev zoo thiab kev nruj: tswj kev du ncauj tsis muaj kev cuam tshuam ntau dua, ua rau sib koom ua ke nyob rau hauv thermal cycling thiab kev ntxhov siab.

Hastelloy X Daim Ntawv Thov

Cov cuab yeej tshwj xeeb ntawm hastelloy x ua rau nws cov khoom siv ntawm kev xaiv rau qhov xav tau tshaj plaws {}} kub cov khoom kub:

1. Aerospace thiab dav hlau tshuab: cov cans sib txuas, cov pob txha caj dab, cov khoom sib txuas, cov khoom sib txuas tom qab, thiab ntsaws ruaj ruaj. Nws lub peev xwm los tiv thaiv cov cua sov thiab kev kub ntxhov ua pa hluav taws xob hauv lub dav hlau engines yog qhov tseem ceeb.
2. Kev lag luam roj: kev sib txuas, cov lus tsis zoo, tawg cov lus qhia, thiab cov roj kub kub, thiab cov roj kub kub hauv siab thiab thermal cycling.
3. Kev kho tshav kub kub thiab muaj kev muaj kev muaj zog: muffles, radiants tubes, pob tawb, thiab fixtures raug mob kub thiab muaj peev xwm corrosive atmospheres.
