FAQs

Kev kho cua sov cuam tshuam li cas rau 410 stainless hlau?Kev kho cua sov hloov pauv 410's mechanical zog: annealing (cua sov rau 815-900 degree, txias maj mam) softens nws rau machining thiab sib sau, thaum quenching (cua sov rau 925-1010 degree, txias sai sai hauv roj / dej) thiab tempering (cua sov mus rau 150-370℃rau qib siab). Tempered 410 ua tiav hardness txog 35 HRC, ua rau nws tsim nyog rau cov cuab yeej txiav thiab hnav{10}} cov khoom tiv thaiv. Kev kho cua sov kuj tseem txhim kho lub zog tensile (txog 860 MPa) yam tsis muaj kev cuam tshuam corrosion nyob rau hauv ib puag ncig me me. Tsis zoo li qib austenitic, 410's martensitic qauv tso siab rau kev kho cua sov kom qhib nws lub peev xwm tag nrho.

Puas yog 410 haum rau cov zaub mov-hu rau daim ntawv thov xws li cutlery?Yog lawm, 410 feem ntau yog siv rau kev siv nyiaj txiag -tus phooj ywg cutlery thiab zaub mov- cov hniav ua haujlwm vim nws cov tawv tawv, hnav tsis kam, thiab corrosion kuj nyob rau hauv ib puag ncig me me. Nws 11.5-13.5% chromium cov ntsiab lus tsim cov txheej txheem passive uas tiv thaiv xeb los ntawm cov khoom noj acids thiab dej, thiab nws yog ib qho yooj yim rau sharpen mus rau ib tug ntse ntug. Thaum nws tsis zoo li corrosion-resistant li 304 lossis 316, nws ua tau zoo hauv cov ntawv thov zaub mov qhuav (xws li, stainless hlau diav rawg, riam) thiab yooj yim los ntxuav. Nws ua tau raws li FDA cov zaub mov- tiv tauj cov qauv thaum ua tiav, ua rau nws tus nqi - kev xaiv zoo rau cov khoom loj - tsim cov cutlery.

Yuav ua li cas corrosion tsis kam 410 muaj?410 muab kev tiv thaiv zoo corrosion nyob rau hauv qhov chaw qhuav, tshuaj me me, thiab dej tshiab, tab sis nws tsis tshua muaj kev tiv thaiv rau cov dej ntsev, kua qaub, thiab cov av noo dua qib austenitic. Nws cov ntsiab lus chromium tsim ib txheej oxide passive uas tiv thaiv xeb hauv qhov tsis yog -corrosive chaw, tab sis txheej txheej no tuaj yeem tawg hauv chloride- nplua nuj lossis acidic ib puag ncig. Nws tsis pom zoo rau cov ntug hiav txwv dej, dej hiav txwv, lossis tshuaj lom neeg - ua cov ntawv thov uas 304 lossis 316 yuav tsim nyog dua. Kev tu thiab ziab tsis tu ncua pab tswj nws cov corrosion kuj, ua rau nws zoo tagnrho rau sab hauv tsev, qhuav- siv cov khoom xws li li qub, ncej, thiab cov cuab yeej phais.

410 puas tuaj yeem siv rau siab - hnav cov khoom lag luam?Yog lawm, 410 yog qhov zoo heev rau siab - hnav cov khoom lag luam xws li twj, li qub, thiab cov hniav vim nws cov cua sov- kho hardness thiab hnav tsis kam. Tempered 410 muaj qhov nyuaj txog li 35 HRC, uas tiv thaiv kev puas tsuaj thiab deformation hauv cov khoom txav. Nws cov qauv martensitic muab superior hnav tsis kam piv rau austenitic qib zoo li 304, uas yog softer thiab ntau ductile. Nws kuj yog ib qho yooj yim rau tshuab rau hauv precision Cheebtsam, ua rau nws haum rau kev cai coj qhov chaw. Thaum nws yuav tsum tau lubrication los tiv thaiv galling nyob rau hauv siab - kev sib txhuam daim ntaub ntawv, nws durability thiab nqi{11}}effectiveness ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau industrial hnav Cheebtsam.

Vim li cas 410 sib nqus, thiab qhov no puas cuam tshuam rau nws txoj haujlwm?410 yog sib nqus vim nws cov qauv siv lead ua martensitic, uas aligns magnetic domains nyob rau hauv lub xub ntiag ntawm magnetic teb. Cov cuab yeej sib nqus no tsis cuam tshuam rau nws qhov kev ua tau zoo- nws yeej muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau kev sib nqus nqus (xws li, sib nqus li qub lossis sensors). Tsis zoo li qib austenitic, 410 khaws cov hlau nplaum ntawm chav tsev kub thiab nyob rau hauv feem ntau cov kev ua haujlwm, ntxiv cov nqi ua haujlwm yam tsis muaj kev cuam tshuam lub zog, hardness, los yog corrosion kuj. Nws cov hlau nplaum yog ib qho txiaj ntsig ntawm nws cov muaj pes tsawg leeg thiab cov qauv, ua rau nws muaj ntau yam kev xaiv rau ob qho tib si sib nqus thiab tsis yog- cov ntawv siv hlau nplaum uas lub zog thiab hnav tsis kam yog qhov tseem ceeb.
