301: Tus nqi qis dua, tab sis nrog me ntsis qis dua corrosion tsis kam
Ferritic stainless kav hlau kav: Cov kav dej no muaj cov chromium thiab paub txog lawv tus nqi qis dua piv rau cov hom kev ua kom sov. Txawm li cas los xij, lawv txoj kev xeb corrosion feem ntau yog qis dua. Lawv feem ntau siv hauv kev tsim kho thiab cov ntawv thov dai hniav.
Qhov Zoo:
Tus nqi qis dua piv rau Austenitic Stainless hlau
Cov khoom sib nqus muaj zog, tso cai rau kev txheeb xyuas yooj yim
Qhov tsis zoo:
Qis corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig
Txo lub zog piv rau Austenitic Stainless hlau
Khoom Siv:
430: Qhov feem ntau ferritic stainless hlau, muab kev xaiv zoo nqi
409: Kev Txhim Kho Oxidation Kuj, Haum rau kev siv kub siab xws li cov tso pa tawm tshuab
Martensitic Stainless hlau kav: Cov kav dej no muaj chromium thiab carbon, kev nthuav tawm siab lub zog thiab hardness. Txawm li cas los xij, lawv txoj kev mob corrosion feem ntau yog qis dua. Lawv feem ntau siv rau kev tsim cov cuab yeej thiab cov khoom siv tshuab.
Qhov Zoo:
Lub zog siab thiab hardness, muab cov coj zoo heev thiab cuam tshuam kev thev taus
Zoo tsis kam mus rau qhov kub
Qhov tsis zoo:
Cov tsis zoo corrosion tsis kam piv rau ustenitic thiab ferritic hom
Qis dua qhov chaw, ua rau kev sib tw ntau dua
Khoom Siv:
420: Feem ntau cov martensitic stainless hlau, muab kev sib npaug ntawm lub zog thiab hardness
440: Lub zog siab dua thiab hardness, haum rau kev tsim cov siab-precision cov cuab yeej thiab cov khoom siv
Duplex cov kav hlau stainless hlau: Cov kav dej no ua ke qhov zoo ntawm cov hlau Austenitic thiab Martensitic Stainless hlau, muab ob qho zoo corrosion tsis kam thiab lub zog. Lawv feem ntau siv nyob rau hauv cov roj thiab roj kev lag luam.
Qhov Zoo:
Superior corrosion tsis kam piv rau ustenitic steel hlau, tshwj xeeb tshaj yog nyob hauv chloride daws
Lub zog siab dua li Austenitic stainless hlau, muab cov coj zoo coj tsis kam thiab cuam tshuam
Qhov tsis zoo:
Siab dua tus nqi piv rau ustenitic thiab ferritic stainless hlau
Ntau nyuaj rau cov ntaub, yuav tsum tau cov khoom siv tshwj xeeb thiab cov txuj ci
Khoom Siv:
21cr-6Nn: cov txiv hmab txiv ntoo ruple tsis muaj tshaj plaws, muab qhov sib npaug ntawm cov khoom
22CUs 8NI: Txhim kho kom tsis kam mus rau chloride corrosion, haum rau cov ntawv thov dej hiav txwv
Nickel-alloy kav dej: Cov kav dej no yog tsim los ntawm cov nickel-based alloys, muab kev tshwj xeeb corrosion tsis kam thiab muaj peev xwm tiv taus cov chaw hnyav. Lawv feem ntau siv nyob rau hauv aerospace, marine, thiab kev siv hluav taws xob nuclear.
Qhov Zoo:
Huab Huv Kev Tawm Tsam, Muaj peev xwm ntawm Nrog Ntau yam kev siv ntau yam
Lub zog muaj zog thiab lub siab tsis kam
Qhov tsis zoo:
Tus nqi siab heev piv rau lwm hom hlau stainless
Cov txheej txheem fabrication nyuaj, koj xav tau cov khoom siv tshwj xeeb thiab kev txawj ntse
Khoom Siv:
Hastelloy C-276: siv dav rau nws cov dav corrosion tsis kam
Inconel 625: Lub zog siab thiab kev tawm tsam mus rau ib puag ncig loj
Monel 400: Zoo heev tiv taus rau dej hiav txwv thiab chloride daws
