Tam sim no ntau cov khoom lag luam yuav ua los ntawm stainless hlau xaim hlua khoom.Txhawm rau txheeb xyuas cov khoom cuav thiab tsis zoo stainless hlau, qee qhov kev ntsuas thiab txoj hauv kev tuaj yeem ua.Tab sis ntau tus neeg muas zaub tsis paub yuav ua li cas txheeb xyuas, teev cov txheej txheem kev txheeb xyuas hauv qab no rau koj.
Magnetic test method yog thawj qhov sib txawv ntawm austenitic stainless hlau thiab ferritic stainless hlau txoj kev yooj yim, austenitic stainless hlau yog cov hlau nplaum tsis raug, tab sis tom qab ua haujlwm txias hauv qab lub siab loj yuav muaj qhov sib nqus me ntsis;Tab sis cov ntshiab chrome hlau thiab cov hlau tsis tshua muaj hlau yog cov hlau nplaum muaj zog.
Ib tug zoo kawg li tus yam ntxwv ntawm stainless hlau hlau hlua yog nws inherent corrosion tsis kam rau concentrated nitric acid thiab dilute nitric acid, uas ua rau nws yooj yim kom paub qhov txawv ntawm lwm yam hlau los yog alloys.Tab sis siab carbon 420 thiab 440 steel nyob rau hauv cov nitric acid point test yog me ntsis corroded, non-ferrous hlau ntsib concentrated nitric acid yog tam sim ntawd corroded, thiab dilute nitric acid muaj zog corrosion ntawm carbon steel.
Copper sulfate point test yog ib txoj hauv kev yooj yim kom paub qhov txawv ntawm cov pa roj carbon zoo tib yam thiab txhua hom stainless hlau xaim hlua.Qhov concentration ntawm tooj liab sulfate tov yog 5% -10%.Ua ntej qhov ntsuas qhov ntsuas, qhov chaw sim yuav tsum tau muab tshem tawm kom huv si los ntawm cov roj lossis lwm yam impurities, thiab ib qho chaw me me yuav tsum tau polished los ntawm kev sib tsoo tshuab los yog cov ntaub mos mos, thiab tom qab ntawd cov kua ntsuas cov kua yuav poob mus rau qhov chaw sib tsoo.Ordinary carbon steel los yog hlau nyob rau hauv ob peb lub vib nas this yuav tsim ib txheej ntawm txheej hlau tooj liab, thiab nto ntawm stainless hlau tsis tsim tooj liab los nag lossis tso xim tooj liab.
