Dab tsi cuam tshuam rau corrosion kuj ntawm Stainless Hlau Hex Cap Bolt?

1. Tshuaj muaj pes tsawg leeg
Chromium cov ntsiab lus: Chromium yog lub ntsiab tseem ceeb rau stainless hlau kom tau corrosion kuj, thiab nws cov ntsiab lus feem ntau yog siab tshaj 10.5%. Chromium yooj yim reacts nrog oxygen nyob rau hauv cov huab cua los tsim ib tug ntom chromium oxide tiv thaiv zaj duab xis, uas yuav zoo tiv thaiv sab nraud oxygen, dej thiab lwm yam tshuaj los ntawm ntxiv eroding lub ntsia liaj qhov rooj nto.
Alloy cov ntsiab lus: Nickel tuaj yeem txhim kho corrosion kuj thiab toughness ntawm stainless hlau, ua stainless hlau ruaj khov nyob rau hauv ntau yam corrosive ib puag ncig. Molybdenum tuaj yeem txhim kho pitting thiab crevice corrosion kuj ntawm stainless hlau hauv corrosive media xws li chlorides. Tsis tas li ntawd, qhov sib ntxiv ntawm cov ntsiab lus xws li titanium thiab niobium tuaj yeem pab txhim kho corrosion ntawm stainless hlau. Piv txwv li, titanium tuaj yeem ua kom ruaj khov ntawm cov qauv austenite thiab tiv thaiv intergranular corrosion.
2. Metallographic qauv
Austenitic stainless hlau: xws li 304, 316, thiab lwm yam., muaj corrosion kuj zoo thiab tsis yog-magnetic. Nws yog qhov tsim nyog rau qhov chaw corrosive dav dav thiab lub sijhawm uas muaj kev tiv thaiv corrosion siab.
Ferritic stainless hlau: Nws muaj qhov tsis muaj zog corrosion kuj, tab sis tseem tuaj yeem siv rau qee qhov chaw tsis muaj zog corrosive. Nws muaj hlau nplaum thiab yog tus nqi qis.
Martensitic stainless hlau: Nws cov khoom siv kho tshuab tuaj yeem hloov kho los ntawm kev kho cua sov, tab sis nws cov kev tiv thaiv corrosion tsis zoo dua li ntawm austenitic stainless hlau. Nws yog feem ntau siv nyob rau hauv qhov chaw uas yuav tsum tau siab rau lub zog thiab hardness thiab kuj me ntsis corrosion ib puag ncig.
3. Cov txheej txheem tsim khoom
Cov txheej txheem smelting: Advanced smelting technology, cov cuab yeej thiab cov txheej txheem tuaj yeem tswj cov ntsiab lus ntawm cov hlau alloy zoo dua, tshem tawm cov impurities, thiab xyuas kom muaj kev ruaj ntseg ntawm cov cua txias ntawm cov hlau billet, yog li txhim kho cov khoom zoo thiab corrosion kuj. Txawm li cas los xij, qee qhov me me steel mills muaj cov khoom siv rov qab thiab cov txheej txheem, thiab cov hlau tsis muaj steel bolts lawv tsim yuav muaj ntau impurities thiab tsis zoo corrosion kuj.
Kev kho deg: Passivation kev kho ntawm lub ntsia liaj qhov rooj saum npoo tuaj yeem txhim kho nws cov kev tiv thaiv corrosion, thiab ib qho kev ruaj khov passivation zaj duab xis yog tsim los ntawm cov tshuaj los yog electrochemical txoj kev los txhim kho nws cov corrosion kuj. Kos, pits lossis lwm yam tsis xws luag ntawm qhov chaw yuav rhuav tshem qhov kev ncaj ncees ntawm cov yeeb yaj kiab passivation thiab dhau los ua qhov pib ntawm corrosion.
4. Siv ib puag ncig
Media hom: Nyob rau hauv tsis muaj zog corrosive media xws li cua, chav thiab dej, stainless hlau bolts feem ntau muaj corrosion kuj zoo. Txawm li cas los xij, hauv corrosive media xws li muaj zog acid, alkali, thiab ntsev tov, qhov kev pheej hmoo ntawm corrosion yuav nce.
Kub: Feem ntau hais lus, qhov kub thiab txias yuav ua rau cov tshuaj tiv thaiv corrosion thiab txo cov corrosion kuj ntawm stainless hlau bolts. Nyob rau hauv ib puag ncig kub, cov zaj duab xis passivation ntawm stainless hlau yuav puas, los yog intergranular corrosion yuav tshwm sim.
