Cov neeg feem ntau soj ntsuam xyuas stainless steel merits thiab cuav los ntawm kev siv hlau nplaum adsorb stainless hlau. Nyob rau hauv lawv lub tswv yim, yog hais tias tus stainless steel tsis muaj magnetism, cov khoom no yog zoo thiab tiag tiag; On qhov tsis tooj, nws yog suav tias yog raws li fake fake. Nyob rau hauv qhov tseeb, qhov no yog ib tug heev tug-ib tog, unrealistically tsis ncaj ncees lawm txoj kev paub.
Muaj ntau ntau hom ntawm stainless steel, uas yuav tsum tau muab faib ua ob peb pawg raws li lub koom haum qauv ntawm chav tsev kub:
1, Austenitic: xws li: 201.202.301.304.316 thiab lwm yam .;
2, Martensite los yog ferrite: xws li: 430.420.410 thiab lwm yam
3, Austenitic hom yog uas tsis yog-sib nqus los yog weakly magnetic, martensite los yog ferrite yog magnetic.
Feem ntau ntawm cov stainless steels siv raws li cov hniav raj nplooj ntawv yog austenitic hom 304 cov ntaub ntawv, uas yog feem ntau uas tsis yog-sib nqus los yog weakly magnetic. Txawm li cas los, sib nqus tej zaum yuav tshwm sim vim hloov mus hloov los nyob rau hauv tshuaj nyob tus yeees los yog ua tej yam kev mob vim smelting, tab sis qhov no tsis tau yuav tau li Counterfeit los yog unqualified, dab tsi yog qhov vim li cas?
Nws yog hais saum toj no uas austenite yog uas tsis yog-sib nqus los yog weakly magnetic, thiab martensite los yog ferrite yog magnetic. Vim segregation los yog kev tshav kub
kev kho mob thaum lub sij hawm smelting, ib tug me me npaum li cas ntawm martensite los yog ferrite nyob rau hauv austenitic 304 stainless steel yog tshwm sim los. Lub cev lub koom haum. Yog li, 304 stainless steel yuav muaj zog sib nqus.
Nyob rau hauv tas li ntawd, 304 stainless steel yog txias-ua hauj lwm, thiab cov microstructure yog tseem hloov mus rau hauv martensite. Qhov ntau dua qhov txias ua hauj lwm deformation, qhov ntau martensite transformation thiab ntau dua qhov lub magnetic thaj chaw ntawm lub hlau. Zoo li ib tug batch ntawm steel ib daim hlab, nws ua Φ76 hlab uas tsis muaj cuab magnetic induction thiab ua Φ9.5 hlab. Vim lub loj deformation ntawm lub dabtsi yog khoov, sib nqus induction yog cuab kev. Lub lub raj ua yog loj tshaj lub round raj, tshwj xeeb tshaj yog cov angled ib feem, thiab lub deformation yog ntau khaus thiab cov magnetic yog cuab kev ntau.
Nyob rau hauv thiaj li yuav tshem tau cov magnetic thaj chaw ntawm lub 304 steel tshwm sim los ntawm cov saum toj no yog vim li cas, lub austenite qauv yuav tsum tau rov qab los ntawm high-kub tshuaj kho mob mus tshem tawm cov sib nqus.
Nyob rau hauv kev, lub sib nqus ntawm 304 stainless steel tshwm sim los ntawm cov saum toj no yog vim li cas yog tsis nyob rau tib theem li cov magnetic thaj chaw ntawm lwm yam ntaub ntawv xws li 430 thiab cov hlau. Uas yog hais tias, lub sib nqus ntawm 304 steel yeej ib txwm qhia tsis muaj zog sib nqus.
Qhov no yuav qhia rau peb hais tias yog hais tias tus stainless steel sawb yog weakly magnetic los yog tsis sib nqus ntawm tag nrho cov, nws yuav tsum tau txiav txim raws li 304 los yog 316 cov khoom; yog hais tias nws yog magnetic zoo xws li cov carbon steel, nws qhia tau hais tias muaj zog magnetism, vim hais tias nws yog txiav txim tsis yuav 304 khoom.
