Khoom Taw qhia

ASTM B165 Monel 400 Yeeb Nkabtsis zoo li cov khoom lag luam nyuaj ntawm daim ntawv teev cov ntaub ntawv, thiab qhov ntawd yog ib feem ntawm qhov teeb meem. Cov neeg yuav khoom uas tau nyeem cov ntaub ntawv sai sai pom txog 63% npib tsib xee thiab 30% tooj liab thiab xav tias nws tsuas yog lwm qhov siab -nickel alloy qhov chaw ntawm stainless hlau thiab Hastelloy. Nws tsis yog.

Monel 400 yog npib tsib xee- tooj liab alloy (UNS N04400, W.Nr. 2.4360), thiab nws lub neej muaj txiaj ntsig los ntawm kev sib xyaw tshwj xeeb: nws yog ib qho ntawm ob peb hom alloys uas ua dej hiav txwv, dej qab zib thiab hydrofluoric acid tsis muaj flinching, thaum tseem pheej yig txaus los ua pov thawj thaum daim ntawv thov tiag tiag xav tau.

Tshuaj muaj pes tsawg leeg ntawm Monel 400

Cov alloy yog txhais los ntawm ASTM B165 rau seamless yeeb nkab thiab raj, nrog welded yeeb nkab npog los ntawm B725 thiab tshav kub -exchanger raj los ntawm B163. Cov kev txwv tsis pub muaj hauv qab no yog qhov tseem ceeb ntawm B165, tsis yog qhov tseem ceeb - thaum koj piv cov ntawv pov thawj zeb tawm tsam cov spec, cov no yog cov lej tseem ceeb.

Element	Cov ntsiab lus,%	Nws Ua Dab Tsi
Nickel (Ni)	6 3,0mn	Lub hauv paus ntsiab lus; muab kev tiv thaiv rau caustic alkalis thiab txo cov xwm txheej
Copper (Cu)	28.0 - 34.0	Ntxiv rau cov dej hiav txwv thiab tsis yog -oxidizing acids
Hlau (Fe)	2.5 max	Residual los ntawm melting
Manganese (Mn)	2.0 max	Deoxidizer hauv melting
Cov pa roj carbon (C)	0.30 max	Siab tshaj stainless hlau; xav tau rau no alloy
Silicon (Si)	0.50 max	Cov khoom seem
Sulfur (S)	0.024 max	Tuav qis rau kev ua haujlwm kub

Mechanical Properties (ASTM B165, yam tsawg kawg nkaus)

Zoo li feem ntau wrought npib tsib xee alloys, Monel 400 yog muab muag muag (annealed). Nws tsis yog siab - lub zog alloy nyob rau hauv txoj kev duplex lossis super duplex yog; koj yuav nws rau corrosion kuj, thiab yog hais tias lub zog yog lub ntsiab tsav tsheb lwm yam khoom yuav tsum tau nyob rau hauv lub shortlist xwb.

Khoom	Tus nqi (yam tsawg kawg)
Tensile zog	483 MPa (70 ksi)
Yield zog (0.2% offset)	172 MPa (25 ksi)
Elongation nyob rau hauv 50 mm	35%
Hardness	Feem ntau hauv qab HB 217 nyob rau hauv cov mob annealed

Lub cev khoom tsim nyog nco ntsoov

Ob qhov tseeb ntawm lub cev ua rau cov neeg tsis tau siv cov hlau ua ntej. Monel 400 yog magnetic. Nickel cov ntsiab lus siab tshaj 60% khaws cov khoom ferromagnetic ntawm chav tsev kub, uas yog qhov tseem ceeb yog tias cov kav dej khiav ze ntawm qhov ntsuas los yog qib sib nqus ntsuas - carbon steel kuj yuav sib nqus, tab sis cov neeg yuav khoom piv nws tawm tsam austenitic stainless hlau (uas tsis yog{5}} sib nqus) feem ntau tsis nco qab.

Khoom	Tus nqi
Qhov ntom	8.80 g / cm3
Melting ntau	1300 - 1350 C
Modulus ntawm elasticity	Txog 180 GPa
Sib nqus teb	Ferromagnetic nyob rau hauv chav tsev kub

Qhov ceev kuj hloov qhov hnyav piv. Ntawm 8.80 g / cm3, Monel 400 yog kwv yees li 11% hnyav dua 304 stainless (7.93 g / cm3) thiab ze li ntawm 12% hnyav dua carbon steel (7.85 g / cm3). Rau qhov ntev ntawm cov yeeb nkab, freight thiab kev txhawb nqa loads ua raws.

Qhov twg yeej - thiab qhov twg Nws Tsis

Lub alloy muaj cov lus piav qhia meej txog txoj haujlwm. Nws ua haujlwm ntws dej hiav txwv zoo dua li cov hlau tsis muaj steel feem ntau vim nws tiv cov tshuaj chloride pitting nyob rau hauv tej yam kev mob uas 304 los yog 316 yuav pit. Nws yog cov khoom siv rau hydrofluoric acid (HF) kev pabcuam - refinery alkylation units thiab acid-kab kab yuav luag txhua zaus Monel. Nws kuj tiv taus cov dej qab ntsev muaj zog uas cov hlau tsis muaj zog raug kev nyuaj siab-corrosion tawg.

Nws muaj kev txwv nyuaj. Oxidizing acids xws li nitric acid tau tawm, vim tias tooj liab -nickel tshuav nyiaj li cas tsis tiv thaiv lawv. High-kub sulfur- muaj cov pa roj kuj tuaj yeem tawm tsam nws, thiab nws tsis yog qhov hloov pauv rau 316L hauv cov txheej txheem tshuaj chloride dav dav - 316L yog pheej yig dua thiab feem ntau txaus. Qhov kev txiav txim siab los qhia Monel 400 yuav luag txhua zaus tsav los ntawm ib qho ntawm peb cov kua dej: seawater, HF, los yog concentrated caustic.

Kev pabcuam	Kev ua tau zoo
Dej hiav txwv ntws	Zoo heev - cov khoom siv rau marine piping thiab heat exchangers
Hydrofluoric acid (HF)	Cov ntaub ntawv siv rau alkylation thiab acid kab
Caustic soda (concentrated)	Zoo heev mus txog high concentrations
Nitric acid, oxidizing acids	pluag - tsis qhia
High -kub sulfur gases	Tsis zoo - corrosion tus nqi nce sai
General chlorides (xws li brine)	Zoo dua 304/316 tsuas yog qhov chaw pitting hnyav; txwv tsis pub 316L yog tus nqi zoo dua

Qhov ntau thiab tsawg thiab cov ntawv xa khoom

Monel 400 yeeb nkab feem ntau txiav txim raws li seamless raj (ASTM B165, txog li ntawm NPS 8 hauv cov qauv tsim, nyob ntawm lub zeb) lossis raws li cov yeeb nkab welded (B725). Thaum tshav kub kub- cov raj xa hluav taws xob, uas yog qhov feem ntau ntawm kev txiav txim hauv hiav txwv thiab tshuaj lom neeg tiag tiag, ua raws li B163 thiab feem ntau yog kos thiab ci dua - tiav. Phab ntsa thicknesses ua raws li lub sij hawm stainless series (SCH 10S txog XXS) vim hais tias cov yeeb nkab yog ntsuas tawm tsam tib sab nraud diameters li stainless yeeb nkab nyob rau hauv feem ntau export lag luam.

Vim tias cov hlau yog txias-kos ntau dua li kub-extruded rau qhov me me, kam rau ua raws li kos- raj xyaum. Qhov xaus yog ib txwm muab cov khoom siv dawb los yog beveled, thiab qhov ntev yog ib qho random, ob chav random, los yog txiav kom txiav txim siab - txiav ntev yog feem ntau rau cov cua sov- cov khoom sib pauv, qhov twg txhua lub raj muaj qhov ntev.

Dab tsi los tso rau ntawm Kev Yuav Khoom

Kev txiav txim luv luv uas yooj yim hais tias "Monel 400 yeeb nkab" feem ntau rov qab los nrog qee yam uas tus neeg yuav khoom tsis tau xav txog. Cov lus qhia tshwj xeeb yuav tsum nqa, yam tsawg kawg nkaus: tus qauv (B165, B725 lossis B163), UNS (N04400), NPS thiab lub sijhawm, qhov ntev, qhov kawg, thiab kev soj ntsuam yuav tsum tau ua. Cov naj npawb cua sov yog qhov yuav tsum tau ua rau kev taug qab, thiab daim ntawv pov thawj zeb xeem rau EN 10204 3.1 yog tus qauv kev cia siab. Kev txheeb xyuas PMI ntawm daim ntawv txais nyiaj yog kev tuav pov hwm pheej yig - npib tsib xee- tooj liab alloy yog ib qho yooj yim rau kev tsis pom kev pom, thiab nws kim heev kom pom tom qab vuam tias qib tsis raug mus rau hauv kab.
