Hauv phau ntawv qhia no, peb mam piav qhiaQhov sib txawv ntawm 18/8 thiab 304 stainless hlau, cov lej no txhais li cas, thiab ib qho twg zoo dua rau koj daim ntawv thov. Txawm hais tias koj yog lub tsev ua noj ua haus, tus kws tshaj lij tus kws tshaj lij, lossis tus kws tshaj lij kev lag luam, cov ntaub ntawv no yuav pab koj ua cov khoom zoo xaiv.

Dab tsi yog 18/8 stainless hlau?
18/8 Stainless hlau yog ib qho kev siv labing uas muaj nyob hauv cov neeg siv khoom, tshwj xeeb tshaj yog cookware. Cov lej xa mus rau feem pua ntawm chromium (18%) thiab npib tsib xee (8%) hauv cov hlau stainless. Ob lub ntsiab lus no yog qhov tseem ceeb rau corrosion tsis kam thiab ci. Nws tiv taus xeb thiab stains, tsis hnov mob nrog zaub mov, thiab yog ruaj khov txaus rau txhua hnub siv.

18/8 Stainless Steel

Dab tsi yog 304 stainless hlau?

304 Stainless hlau yog kev tsim qauv ua haujlwm los ntawm American Hlau thiab Hlau Lub Koom Haum (AISI) rau cov hlau uas nquag siv tsis tau siv. Nws cov tshuaj lom neeg muaj pes tsawg leeg yog feem ntau: 18-20% chromium, 8-10.5% npib tsib-ees, uas txhais tau tias 18/8 stainless hlau yog ib subset ntawm 304 stainless hlau. Txhua 18/8 Stainless hlau yog 304 stainless hlau, tab sis tsis tag nrho 304 stainless hlau yog nruj me ntsis 18/8 stainless hlau.

yog 18/8 stainless hlau tib yam li 304

Corrosion Kuj
18/8 Stainless Hlau (18% cr-8% ni) thiab 304 stainless hlau (18-20% cr-8-10.5% dej thiab qaug zog acid thiab cov kua qaub tsis muaj zog; 304 Muaj cov ntsiab lus dav dav ntawm cov ntsiab lus ntawm npib tsib xee, yog li nws yog me ntsis hauv cov av noo lossis me me chloride ion ib puag ncig, tab sis qhov sib txawv tsis tseem ceeb hauv cov ntawv thov tiag tiag.

Hnav Tsis kam
Ob qho tib si yog Austenitic stainless hlau, uas zoo sib xws annealed hardness (hv tsawg dua los yog sib npaug nrog 200), thiab tsis muaj qhov sib txawv hauv kev hnav tsis kam; Tom qab ua haujlwm txias, lub hardness yog nce synchronously (HV tuaj yeem mus txog 300+), thiab cov hnav tsis zoo yog txhim kho cov teeb meem tsis muaj kev phom sij. Thaum cov kev coj zoo yuav tsum muaj, kev kho deg yog yuav tsum tau.

Lub magnetism
Ob qho tib si tsis - cov ntaub ntawv sib nqus (Austenitic qauv (Ausenitic qauv) nyob rau hauv cov xwm txheej; Txias ua haujlwm (xws li Stamping) yuav ua rau ib nrab martensitic theem kev hloov pauv thiab tsim cov hlau nplaum tsis muaj zog. Ob lub ntaub ntawv coj tib yam thiab tuaj yeem rov qab los rau tsis- sib nqus tom qab cua sov thiab annealing.

Luam ntawv
Ob qho tib si muaj vuam zoo, khoov tau zoo thiab stamping kev ua tau zoo, nrog elongation ntawm ntau dua los yog sib npaug rau kev sib sau ua ke; 18/8 muaj kev ua tau zoo dua qub vim nws cov muaj zog dua, thiab 304 tau muaj zog dua rau qhov sib txawv, tab sis tag nrho kev ua nyuaj sib txawv yog qhov me me.

Qhov twg yog qhov zoo dua: 18/8 lossis 304 stainless hlau?

Technically, 304 stainless hlau yog qhov zoo dua, vim tias nws suav nrog ntau dua ntawm cov roj ntsha tsis kam thiab ua tau zoo dua hauv kev lag luam thiab chaw muaj kev nyab xeeb. Txawm li cas los xij, rau tsev neeg thiab zaub mov-} qib rau qib, 18/8 stainless hlau yog qhov tseem ceeb sib npaug rau 304 thiab ua tau zoo heev.

Yog tias koj nyob nraum cov khoom siv tsourcing rau cov ntaub thaiv kev lag luam, khoom siv kho mob, lossis siv sab nraum zoov, ib txwm xaiv tau muaj muaj ntawv pov thawj 304 stainless. Yog tias koj tab tom yuav khoom noj cookware lossis chav ua noj, 18/8 stainless hlau yuav ua tau raws li koj cov kev xav tau zoo heev thiab kev nyab xeeb.
