Cov lus teb luv luv: Nickel Alloy tsis tuaj yeem muaj zog dua
Lub zog nyob ntawm qib thiab qhov kub thiab txias, tsis nyob ntawm tsev neeg lub npe. Nickel-chromium- hlau alloy xws li Alloy 600 raug nqi ntau dua li cov hlau tsis muaj steel, tab sis nws tuav nws lub zog thiab nws cov corrosion kuj zoo dua ntawm qhov kub thiab txias. Ntawm chav tsev kub daim duab tuaj yeem thim rov qab: nag lossis daus- cov hlau tsis muaj zog xws li 17-4PH tuaj yeem muaj zog dua li cov nickel alloy. Qhov kev txiav txim siab ua haujlwm yog li ntawd los ntawm peb yam, uas yog tus nqi, kev pabcuam kub thiab xav tau lub zog.
Dab tsi ua Stainless Hlau Stainless
Stainless hlau yog hlau-raws li alloys uas muaj ntau tshaj li ntawm 10.5% chromium los ntawm qhov hnyav, cov chromium ua ib nyias, tus kheej - kho oxide txheej uas tiv thaiv cov hlau los ntawm xeb thiab los ntawm feem ntau cov ntaub ntawv ntawm corrosion. Txhua lub stainless hlau yog corrosion-resistant dua li cov pa roj carbon zoo tib yam, uas yog vim li cas tsev neeg tshwm nyob rau hauv txhua yam ntawm chav ua noj cutlery thiab structural tsev Cheebtsam rau biomedical li thiab khoom noj khoom haus - khoom npaj.
Tsib Tsev Neeg Stainless Hlau
Austenitic: pawg loj tshaj plaws, tsis yog -sib nqus, feem ntau ductile thiab feem ntau cov corrosion resistant, nrog ib tug equiaxed grain qauv.
Ferritic: chromium- nplua nuj thiab sib nqus, nrog lub zog nruab nrab thiab ua haujlwm zoo rau kev ntxhov siab corrosion tawg.
Martensitic: hardenable los ntawm quenching, muaj zog ntau dua tab sis qis corrosion kuj thiab lath - hom qauv.
Duplex: sib xyaw austenitic thiab ferritic microstructure uas sib xyaw ua ke muaj zog nrog cov tshuaj chloride zoo.
Precipitation hardening: ntxiv dag zog los ntawm precipitates tsim thaum lub sij hawm tswj kev laus, muab lub zog siab heev hauv qib xws li 17-4PH.
Cov npe piav qhia txog microstructure uas tsim nyob rau hauv txhua lub alloy, thiab microstructure tswj kev lag luam - tawm ntawm lub zog thiab corrosion kuj. Austenitic qib yog cov ductile tshaj plaws thiab feem ntau corrosion resistant; Martensitic qib muaj zog ntau dua tab sis tsawg dua corrosion resistant. Qhov loj, ntau equiaxed austenitic grain qauv yog precisely dab tsi ua uas ua ke ntawm cov khoom thaum nws muab piv nrog cov finer lath qauv ntawm cov qib martensitic.
Yuav ua li cas ib tug Nickel -Chromium-Iron Alloy Sib piv
Ib tug npib tsib xee -chromium- hlau alloy xws li Alloy 600 pib los ntawm ib tug npib tsib xee puag ntawm tsawg kawg yog 72% es tsis yog ib tug hlau puag. Nws yog ib qho -theem austenitic cov ntaub ntawv ntxiv dag zog los ntawm cov khoom siv tshuaj, thiab nws muab ob yam uas stainless hlau tsis tuaj yeem sib xws: lub zog tuav thiab corrosion kuj ntawm qhov kub siab, ua ke nrog kev ua haujlwm zoo rau chloride kev nyuaj siab corrosion cracking thiab oxidising thiab txo cov tshuaj lom neeg. Tus nqi yog tus nqi. Cov hlau muaj ntau nickel thiab chromium ntau dua li 300-series stainless hlau, yog li ob qho tib si cov khoom siv raw thiab cov khoom tiav yog kim dua.
Tus nqi, Kub thiab lub zog: Yuav xaiv li cas
Yog tias tus nqi qis dua thiab lub zog nruab nrab yog qhov tseem ceeb, ib qho stainless hlau feem ntau yog cov lus teb raug.
Yog hais tias ib feem yuav tsum muaj sia nyob qhov kub thiab txias ua ke nrog oxidation, carburisation thiab aggressive corrosion, nickel -chromium- hlau alloy yog qhov kev xaiv zoo dua.
Yog tias chav siab tshaj plaws - qhov kub thiab txias ntawm tus nqi nruab nrab yog xav tau, nag lossis daus- cov hlau tsis muaj zog xws li 17-4PH feem ntau ua haujlwm zoo dua cov nickel alloy.
Yog tias cov khoom tseem ceeb thiab ib puag ncig hnyav, ntsuas tus nqi ntawm cov alloy tiv thaiv tus nqi ntawm kev ua tsis tiav ntxov ua ntej txo qhov kev qhia tshwj xeeb.
Cov lus nug nquag
Q: Puas yog nickel alloy muaj zog dua stainless hlau?
Tsis tau. Ntawm chav tsev kub qee qhov nag lossis daus- cov hlau tsis muaj zog muaj zog dua, thaum nyob rau hauv qhov kub siab cov nickel-chromium- hlau alloys khaws cia ntau dua ntawm lawv lub zog.
Q: Vim li cas nickel -chromium- hlau alloys kim heev?
Lawv muaj ntau cov npib tsib xee thiab chromium, uas yog cov khoom siv hluav taws xob kim heev, thiab lawv yuav tsum tau ceev faj ntau dua melting, ua thiab kev tswj kom zoo dua li cov hlau tsis zoo.
Q: Qhov twg stainless hlau yog qhov muaj zog tshaj?
Cov nag lossis daus- cov qib hardening xws li 17-4PH ncav cuag lub zog siab tshaj plaws, ua raws li qib martensitic, thaum qib austenitic pauv lub zog rau ductility thiab corrosion kuj.
Q: Qhov kub npaum li cas yog nickel alloy ua qhov kev xaiv zoo dua?
Lub crossover nyob ntawm lub luag haujlwm, tab sis nws feem ntau yog nyob rau hauv cheeb tsam uas cov hlau tsis muaj steel pib poob lub zog thiab oxidation tsis kam, feem ntau yog ob peb puas degrees Celsius thiab siab dua.
Q: Puas yog 17-4PH muaj zog dua Alloy 600?
Yog lawm, nyob rau hauv cov neeg muaj hnub nyoog 17-4PH nce mus txog chav tsev kub siab dua, tab sis nws lub zog thiab oxidation tsis kam poob sai dua li qhov kub thiab txias.
Q: Puas yog stainless hlau hlau nplaum?
Nws nyob ntawm tsev neeg. Austenitic qib feem ntau tsis yog- sib nqus, thaum ferritic, martensitic thiab nag lossis daus- qib hardening yog sib nqus.
