Puas yuav SUS304 Stainless hlau xeb?
ThaumSUS304 stainless hlauyog heev resistant raucorrosion, nwstuaj yeem xebnyob rau hauv tej yam kev mob. Nov yog vim li cas:
1. Tawm rau Hnyav Ib puag ncig:
SUS304 yog qhov zoo heev rau xeb thiab xeb thaum raug rau ib puag ncig me me mus rau nruab nrab. Txawm li cas los xij, chlorides, dej ntsev, lossis acidic tej yam kev mob tuaj yeem ua rau pitting thiab crevice corrosion dhau sijhawm.
Marine ib puag ncig, pas dej da dej, thiab lwm qhov chaw uas muaj ntsev ntau lossis tshuaj chloride tuaj yeem ua rau SUS304 stainless hlau degrade, ua rau xeb lossis staining.
2. Kev kho tsis raug:
Rust tuaj yeem tsim yog tias SUS304 tsis raug tswj kom raug. Cov av, roj, thiab lwm yam kab mob tuaj yeem cuam tshuam cov txheej txheem tiv thaiv passive oxide uas ib txwm ua rau saum npoo ntawm SUS304. Qhov no ua rau nws yooj yim rau oxidation, uas ua rau xeb.
Kev tu thiab tu tsis tu ncua yog tsim nyog los khaws cov corrosion kuj ntawm SUS304 stainless hlau.
3. Kev puas tsuaj:
SUS304 kuj tuaj yeem xeb yog tias qhov chaw khawb lossis puas, uas cuam tshuam rau txheej oxide. Txhua qhov kev puas tsuaj rau txheej tiv thaiv nthuav tawm cov hlau rau ib puag ncig, ua rau nws raug corrosion.
4. High -Tsub Ib puag ncig:
Kev raug kub ntev ntev tuaj yeem ua rau SUS304 poob nws qhov kev tiv thaiv corrosion. Nyob rau hauv ib puag ncig uas kub tshaj 870℃(1600℃F), cov khoom muaj peev xwm tiv thaiv xeb yog txo qis.
Tiv thaiv xeb ntawm SUS304 Stainless hlau
Txhawm rau kom ntseeg tau tias SUS304 stainless hlau tuav nws txoj kev tiv thaiv corrosion thiab ua haujlwm ntev, ua raws li cov lus qhia yooj yim no:
1.Regular Cleaning: Khaws qhov chaw kom huv si kom tsis txhob muaj cov khoom tsim - av, roj, lossis chlorides. Siv cov tshuaj ntxuav me me thiab dej sov los ntxuav qhov chaw. Tsis txhob siv cov tshuaj hnyav los yog cov cuab yeej ntxuav tu uas tuaj yeem ua rau lub ntsej muag puas.
2.Protective Txheej: Nyob rau hauv ib puag ncig uas SUS304 raug chlorides los yog ntsev, xav txog kev siv cov txheej tiv thaiv los yog kev kho mob passivation los txhim kho cov khoom tiv thaiv corrosion.
3.Xav txog SUS316: Yog tias koj xav tau kev tiv thaiv corrosion ntau dua, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj chloride- nplua nuj ib puag ncig xws li marine lossis tshuaj ua haujlwm, xav txog SUS316 stainless hlau, uas muaj molybdenum rau kev tiv thaiv zoo dua.
Kev sib piv Corrosion Resistance: SUS304 vs SUS316
