Monel 400 thiab Monel K500 yog ob qho tib si Monel alloys. Qhov txawv yog dab tsi?
Monel 400 Description
Monel 400 alloy yog ib hom hlau uas tuaj yeem siv rau hauv dej hiav txwv, tshuaj kuab tshuaj, ammonia sulfur chloride, hydrogen chloride, ntau yam acidic media xws li sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, organic acids, nickel-based alloy. cov khoom siv nrog zoo corrosion kuj nyob rau hauv alkaline media, ntsev thiab molten ntsev. Monel 400 alloy kuj muaj cov khoom siv kho tshuab zoo, ntau yam kev siv kub los ntawm qis mus rau qhov kub siab, zoo vuam zog thiab nruab nrab thiab siab zog. Monel 400 feem ntau yog siv rau hauv kev lag luam tshuaj thiab petrochemical, nrog rau kev txhim kho marine thiab lwm yam kev lag luam. Nws tuaj yeem siv los tsim ntau yam khoom siv hluav taws xob, boiler pub dej rhaub, roj av thiab cov kav dej tshuaj, ntim, yees, tso tsheb hlau luam, li qub, twj tso kua mis, reactors, shafts, thiab lwm yam. raws li cov ntaub ntawv. Siv dej txias thaum ntxiv cov tshuab ua haujlwm siab. Cov ntaub ntawv shrinks thaum lub sij hawm ua, yog li yuav tsum tau them nyiaj mloog mus rau lub processing shrinkage nyiaj kom paub meej qhov tseeb. Monel 400 muaj kev ua tau zoo vuam thiab siv tau TIG thiab MIG txoj kev. Nws tuaj yeem siv Monel lub cev lossis EniCu-7 hlau thiab electrode; los yog phau ntawv arc vuam thiab submerged arc vuam; nws tuaj yeem welded nrog carbon steel thiab qis alloy steel.
Monel K500 piav qhia
Monel K500 alloy yog ib tug tshiab alloy nrog zoo heev corrosion kuj thiab siab zog thiab hardness tshaj Monel 400. Qhov no yog vim qhov sib ntxiv ntawm Al, Ti thiab lwm yam rau cov hlau, thiab tom qab ib tug tej yam kev kho cua sov, muaj dispersed intermetallic tebchaw ntawm lub matrix. Lub koom haum qauv yog ib-theem austenite qauv thiab yog precipitated los ntawm dispersed Ni3 (Al, Ti) nag lossis daus theem. Monel K500 muaj kwv yees li peb zaug lub zog tawm los thiab ob zaug ntawm lub zog tensile ntawm Monel 400, thiab cov khoom siv tshuab siab dua tuaj yeem tau txais los ntawm kev ua haujlwm txias lossis hnub nyoog hardening. Monel K500 alloy muaj tib yam corrosion kuj zoo li Monel 400 alloy. Monel K500 alloy yog tsuas yog siv rau lub twj tso kua mis thiab impellers, conveyor scrapers, roj zoo laum rings, elastic qhov chaw, valve gaskets, thiab lwm yam. Lwm tus kuj tsim tau ntau yam khoom siv hluav taws xob sib pauv, boiler pub dej rhaub, roj av thiab tshuaj kav dej, ntim, yees. , tso tsheb hlau luam, li qub, twj tso kua mis, reactors, shafts, thiab lwm yam. Vim nws tsis tshua muaj corrosion nqi nyob rau hauv cov dej hiav txwv ntws thiab lub siab lub zog ntawm no alloy, Monel K500 yog haum rau manufacturing centrifugal twj shafts uas yog resistant rau seawater corrosion. Haum rau ob qho tib si zoo li qub thiab ntws dej hiav txwv.
Qhov sib txawv ntawm Monel 400 thiab Monel K500
Monel400 is composed almost entirely of nickel (>63%) thiab tooj liab (28-34%), tsuas yog me me ntawm hlau, manganese thiab lwm yam kab kawm. Nickel thiab tooj liab yog soluble nyob rau hauv ib leeg, yog li lub microstructure muaj ib theem. Nws tuaj yeem ua kom muaj zog los ntawm kev ua haujlwm txias tab sis tsis yog los ntawm kev kho cua sov. Alloy 400 muaj lub zog siab dua piv rau lwm cov hlau alloys, thiab nws cov khoom cuam tshuam tseem nyob ntawm qib qis dua xoom mus rau 480 degree. Txawm li cas los xij, lub zog ntawm Monel400 txwv nws txoj kev siv hauv kev siv ntau yam qauv. Monel K500 tau tsim kho kom dhau qhov kev txwv no. Nws muaj pes tsawg leeg yog tib yam li Monel400, tab sis txhuas thiab titanium ntxiv rau me me (3-4% tag nrho). Aluminium thiab titanium sib xyaw ua ke los tsim cov kab mob me me uas tuaj yeem tswj tau los ntawm kev kho cua sov. Tom qab forging lossis dov, cov hlau puag ncig tau txais kev kho cua sov, ua kom nws nyob rau hauv qhov kub thiab txias rau ob peb teev thiab tom qab ntawd maj mam txias hauv huab cua. Cov txheej txheem no ua kom ntseeg tau tias ntau npaum li aluminium thiab titanium tuaj yeem raug muab rho tawm los ntawm kev daws teeb meem thiab tsim kom muaj kev sib raug zoo, kev sib cais dav. Cov nag xob nag cua no ua rau muaj kev txhim kho tseem ceeb hauv cov khoom siv kho tshuab - 4-fold nce lub zog tawm los thiab 2-fold nce tensile zog. Lub zog muaj zog ntawm Monel K500 txhais tau tias nws tuaj yeem siv tau zoo ntawm cov khoom sib tw ntau dua xws li marine shafts, valve stems, fasteners, tov khoom thiab stirrer shafts nrog rau cov kws kho mob hniav, laum dab tshos thiab cov khoom siv hluav taws xob. Txij li thaum muaj pes tsawg leeg ntawm Monel K500 zoo ib yam li Monel 400, cov tshuaj lom neeg yooj yim thiab corrosion kuj tseem zoo ib yam. Muaj kev sib cav tias Alloy K500 tej zaum yuav muaj kev cuam tshuam ntau dua rau kev ntxhov siab corrosion tawg nyob rau hauv cov xwm txheej txwv, tab sis qhov no feem ntau yog vim nws siv hauv kev siv kev ntxhov siab ntau dua (vim nws lub zog siab dua).
Txij li cov kev qhia tshwj xeeb ntawm Monel K500 tsis muaj qhov tsis txaus ntseeg piv rau Monel400, thiab nrog kev txhim kho tseem ceeb hauv lub zog, ntau daim ntawv thov tshiab tau qhib, yog li kev lag luam siv Monel K500 cov ntaub ntawv muaj ntau dua.
