Stainless hlau hom thiab qib yog ntau heev, 304 stainless hlau cov khoom yog stainless hlau nyob rau hauv kev siv ntawm ntau lub teb chaws lees paub zaub mov-qib stainless hlau, tshuaj corrosion kuj thiab electrochemical corrosion kev ua tau zoo nyob rau hauv cov hlau sab hauv yog zoo dua titanium alloys. 304 stainless hlau tshav kub-resistant, tshav kub-resistant, tab sis kuj resistant rau kub tsis tshua muaj kub thiab txawm tsis kam mus rau ultra-low kub, siv nyob rau hauv kev tsim khoom ntawm high-qib tsev cov khoom. 304 stainless hlau alloy cov ntsiab lus siab dua, yog li tus nqi siab dua li cov hlau zoo tib yam, uas feem ntau ua rau cov tub lag luam tsis zoo ua lag luam ntau dua nrog lwm cov hlau tsis zoo li 304 stainless hlau, thiab lwm yam stainless hlau. Tus nqi ntau dua li cov hlau zoo tib yam, uas feem ntau ua rau kev lag luam tsis zoo yog ntau dua nrog lwm cov hlau tsis zoo li 304 stainless hlau, peb yuav tsum paub yuav ua li cas txheeb xyuas 304 stainless hlau thiab lwm yam stainless hlau.
Traditional identification txoj kev yog:
Txoj kev ib, kev txheeb xyuas cov xim thiab lustre, tom qab pickling ntawm stainless hlau, xim nto thiab luster ntawm nyiaj thiab huv si, xim nto thiab luster ntawm stainless hlau tsis pickling: chromium-nickel steel yog xim av-dawb, chromium hlau yog brownish. -dub, chromium-manganese nitrogen yog dub. Txias dov unannealed chromium-nickel stainless hlau, saum npoo nyiaj dawb nrog reflections. Txoj kev no yuav tsum muaj lub qhov muag tshwj xeeb rau cov hlau tsis muaj steel, thiab ntau yam ntawm cov ntaub ntawv stainless hlau tau cuam tshuam nrog cov kws tshaj lij kom paub qhov txawv.
Txoj kev ob, nrog cov hlau nplaum los txheeb xyuas, cov hlau nplaum tuaj yeem paub qhov txawv ntawm ob hom stainless hlau. Vim hais tias chromium stainless hlau tuaj yeem nyiam los ntawm cov hlau nplaum hauv txhua lub xeev, tab sis cov hlau nplaum siab manganese uas muaj cov manganese siab tsis yog hlau nplaum, ob qho no tuaj yeem txheeb xyuas tau siv cov hlau nplaum. Yog li ntawd, txawm hais tias cov hlau nplaum tuaj yeem paub qhov txawv ntawm chromium stainless hlau thiab chromium-nickel stainless hlau, tab sis tsis tuaj yeem paub qhov txawv ntawm qee qhov tshwj xeeb ntawm cov hlau, thiab tsis tuaj yeem paub qhov txawv ntawm cov hlau tshwj xeeb.
Txoj kev peb, potion detection, muaj ib tug stainless hlau kuaj kua nyob rau hauv lub lag luam, raws li lub sij hawm ntawm discoloration, txiav txim lub stainless hlau qauv. 10 vib nas this los yog liab rau qhov zoo tib yam 201 stainless hlau; 50 vib nas this los yog liab rau cov qhabnias 201 stainless hlau; 1 feeb lossis li liab rau 202 stainless hlau; 301 stainless hlau nyob rau hauv 2-3 feeb yuav liab, tab sis cov xim yog lub teeb heev, koj yuav tsum tau saib kom zoo zoo; 3 feeb cov xim tsis hloov, cov xim hauv qab yog me ntsis darker, cov xim hauv qab ntawm stainless hlau. Hloov, hauv qab ntawm cov xim tsaus me ntsis, yog qhov tseeb SUS304 stainless hlau. Txawm li cas los xij, txoj kev no ntawm kev paub qhov txawv ntawm cov hlau tsis muaj hlau tsis tshua muaj, tsuas yog kom paub qhov txawv ntawm ntau hom stainless hlau.
Cov txheej txheem saum toj no ntawm kev txheeb xyuas tsis yog tsuas yog siv ntau txoj hauv kev ntawm kev sib xyaw ua ke, thiab nws cov txiaj ntsig kev sim tsuas tuaj yeem txiav txim siab qee yam ntawm cov hlau tsis muaj steel, tsis tuaj yeem txiav txim siab seb hom alloying cov ntsiab lus twg muaj nyob hauv cov hlau thiab cov ntsiab lus tshwj xeeb. Yog li no, cov txheej txheem kev txheeb xyuas tam sim no tsis zoo tag nrho, qee qhov yuav tsis raug, yog li peb xav tau kev tshawb pom tseeb dua txhais tau tias txhawm rau txheeb xyuas cov hlau tsis huv. Nyob rau hauv xyoo tas los no, txoj kev siv ntau dua yog X-ray fluorescence spectrometry nrhiav kom tau, qhov kev tshawb nrhiav tshuab no tsis tsuas yog ua tiav qhov kev sim tsis muaj kev puas tsuaj nkaus xwb, tab sis kuj ntsuas ceev ceev, cov txiaj ntsig tau zoo dua, kev ua haujlwm kuj yooj yim heev. Vim qhov kev tsim ntawm cov cuab yeej yog me me thiab portable, mus rau qhov chaw soj ntsuam thiab kev lag luam tau coj kev yooj yim heev.
