Nickel Alloy Daim Hlau & Cov Ntawv Qhia & Coils
Txias txias kos thiab cold colded yog qhov npaj rau 2205 duplex cov yeeb nkab steel. Vim yog cov yam ntxwv ntawm cov khoom muaj txiaj ntsig zoo thiab hardness, steel hlau yog qhov nyuaj rau cov txheej txheem dua li cov hlau antenitic. Nws yog qhov yooj yim heev rau kev puas tsuaj, tshwj xeeb rau cov tuab tuab me me thiab cov kav dej loj loj, nws sib xyaw ua haujlwm ntev thiab nyuaj.
Cov qauv tshuaj pab txo qis cov hlau zoo li 304 (1.4301) thiab cov hlau ferritic zoo li 430 yog yooj yim rau kev ua thiab ua kom zoo. Raws li lawv cov npe hais, lawv muaj feem ntau ntawm ib theem, austenite lossis ferrite. Txawm hais tias cov hom no tau zoo rau ntau cov ntawv thov, muaj qee qhov kev siv txuj ci tseem ceeb hauv ob hom.
Cov khoom siv duplex muaj bot cov Austenitic thiab Ferrite qauv hauv cov metallurgy ntawm cov khoom. Cov khoom no nqa cov khoom siv zoo tshaj plaws ntawm ob hom ferritic thiab ustenitic hom steel. Cov kav dej yuav yog kub dov lossis txias txav. Cov kub dov tau cov muaj zog dua thiab cov kev tawm dag zog txias yog seamless thiab raug nyob hauv qhov ntev. Lub yeeb nkab doom nti yog siv hauv cov ntawv thov nrog cov kev xav tau siab.
Hauv cov hlau yas, chav kho kom muaj micructubre muaj lub zog siab ntawm cov qib siab thaum khaws cov qib corrosion thaum khaws cov qib tsis kam ntawm cov qib tsis zoo. Nws tsis yog qhov tsis yooj yim los siv cov hlau no ua cov kev daws teeb meem rau chloride-ntxias kev ntxhov siab tawg, pob taws Achilles ntawm cov hlau tsis xeb hlau.
Rau ntau cov ntawv thov uas 300 series stainless hlau yog qhov raug rau cov chloride kev ntxhov siab tawg, 2205 duplex stainless hlau yog qhov kev daws teeb meem zoo. Kev ntxhov siab corrosion tawg tshwm sim thaum stainless hlau yog raug rau tensile muaj kev ntxhov siab thaum sib cuag nrog cov kev daws teeb meem uas muaj chlorides. Kev kub siab dua kub kuj nce ntxiv qhov kev ua kom muaj kev phom sij ntawm cov hlau tsis muaj mob corrosion.
