Stainless hlau 254SMO-F44
Common Trade Names: 254Mo, F44, UNS 31254, W.Nr 1.4547
Alloy F44 (254Mo)nrog siab concentration ntawm molybdenum, chromium thiab nitrogen, cov hlau no tau zoo heev rau pitting thiab crevice corrosion kev ua tau zoo.Copper txhim kho corrosion kuj nyob rau hauv qee cov kua qaub.Tsis tas li ntawd, vim nws cov ntsiab lus siab ntawm npib tsib xee, chromium thiab molybdenum, yog li ntawd 254SMO muaj kev ntxhov siab zoo corrosion cracking kev ua tau zoo.

Vim li cas 254SMO (F44)?
•Kev siv ntau yam kev paub dhau los tau pom tias txawm tias nyob rau hauv qhov kub thiab txias, 254SMO hauv dej hiav txwv kuj tseem muaj zog tiv thaiv corrosion, tsuas yog ob peb hom stainless hlau nrog qhov kev ua tau zoo no.
•254SMO xws li cov tshuaj bleach ntawv yuav tsum tau rau zus tau tej cov acidic tov thiab cov tshuaj halide oxidative corrosion kuj thiab corrosion kuj yuav muab piv rau cov feem ntau resilient nyob rau hauv lub hauv paus alloy ntawm npib tsib xee thiab titanium alloys.
•254SMO vim muaj cov ntsiab lus nitrogen siab, yog li nws cov khoom siv zog ntau dua li lwm hom austenitic stainless hlau yog siab dua.Tsis tas li ntawd, 254SMO kuj tseem ua kom muaj zog thiab cuam tshuam lub zog thiab zoo weldability.
•254SMO nrog cov ntsiab lus molybdenum siab tuaj yeem ua rau nws siab dua ntawm oxidation nyob rau hauv lub annealing, uas tom qab cov kua qaub ntxuav nrog ntxhib nto tshaj li ib txwm stainless hlau yog ntau tshaj li ntxhib nto.Txawm li cas los xij, tsis muaj kev cuam tshuam rau qhov corrosion kuj ntawm cov hlau no.
254SM (F44) Daim ntawv thov teb:
254SMO yog cov khoom siv ntau lub hom phiaj tuaj yeem siv rau hauv ntau daim ntawv thov kev lag luam:
1. Petroleum, petrochemical khoom, petro-chemical khoom, xws li cov twj tso kua mis.
2. Pulp thiab ntawv bleaching khoom, xws li pulp ua noj, bleaching, ntxuav lim siv nyob rau hauv lub chim thiab lub tog raj kheej siab rollers, thiab hais txog.
3. Fais fab nroj tsuag flue roj desulphurization khoom, siv lub ntsiab qhov chaw: lub nqus ntauwd, flue thiab nres phaj, sab hauv, tshuaj tsuag system.
4. Nyob rau hauv lub hiav txwv los yog dej hiav txwv ua tshuab, xws li fais fab nroj tsuag siv dej hiav txwv kom txias lub nyias-walled Condenser, desalination ntawm hiav txwv dej ua cov cuab yeej, yuav siv tau txawm tias cov dej yuav tsis ntws nyob rau hauv lub ntaus ntawv.
5. Desalination industries, xws li ntsev los yog desalination khoom.
6. Thaum tshav kub kub exchanger, tshwj xeeb tshaj yog nyob rau hauv lub chaw ua hauj lwm ntawm chloride ion.
