Cov riam hauv chav ua noj txhua tsev neeg muaj, tab sis tsis yog txhua tus nkag siab txog cov khoom siv riam hauv chav ua noj.
Tej zaum feem ntau txwv rau thiab nkag siab txog cov khoom siv hlau, stainless hlau, ceramics thiab lwm yam.
Qhov tseeb no cov khoom siv stainless hlau kuj muaj ntau yam, rau cov khoom ntawm stainless hlau riam, qis dua cov ntsiab lus carbon cov ntaub ntawv yog mos, tab sis zoo toughness, yooj yim rau ntug tab sis tsis yooj yim rau vaum ntug, siab dua cov ntsiab lus carbon. cov ntaub ntawv yog qhov nyuaj dua, nruj, zoo dua, yog li yooj yim kom tawg ntug hniav tab sis tsis yooj yim.
Tsis tas li ntawd, qhov hardness ntau dua, ruaj khov dua, hardness nce 1, ntse durability tuaj yeem nce 20%, qhov no yog cov riam ceramic tuaj yeem ua lub neej dawb hauv qhov tseeb (
Tab sis cov riam ceramic yooj yim tawg ntug)
.
Cia peb saib seb hom kev siv feem ntau yog dab tsi.
20 cr13: rab ntaj tsawg kawg siv cov khoom siv, cov ntsiab lus tsis tshua muaj carbon,
Nyob rau hauv pem hauv ntej ntawm cov Numbers sawv cev ntawm cov ntsiab lus ntawm txhiab lub sij hawm ntau tshaj 20, txiav txim siab rau steel lub zog, feem pua ntawm Cr yog 13 qab chrome cov ntsiab lus, cuam tshuam rau corrosion kuj thiab durability, ntse qub carbon daim ntawv lo yog standard per mil, xws li 2 cr12, 3 cr13)
Hniav kuj yog mos, yooj yim rau ntug, tab sis Yi Fu sib tsoo.
30 cr13: qhov tseem ceeb tshaj plaws ua cov khoom siv riam, cov lus qhuab qhia ntawm cov khoom nruab nrab, ntse durability yog tsawg, thaum nyuam qhuav yuav yog ntse heev, nws yuav tsis ntev ua ntej yog phem, yuav tsum tau nquag.
40 cr13: cov khoom siv hauv nruab nrab-ntau riam, cov ntsiab lus carbon yog nce, tab sis tag nrho cov txiaj ntsig kev txhim kho tsis pom tseeb.
50 cr15mov: domestic high-end riam khoom, cov ntsiab lus carbon mus txog 50, cov ntsiab lus chromium kuj tau txhim kho, kuj koom nrog molybdenum thiab vanadium, yog li tsis muaj teeb meem los ntawm cov yam ntxwv ntawm hardness thiab toughness yog tag nrho cov loj heev nce qib, qee lub ntiaj teb- chav kawm hom xws li lub teb chaws Yelemees zwilling, WMF cov lus qhia yooj yim rau nruab nrab riam nrog cov khoom siv no.
Lub zog ruaj khov, txhim khu kev tiv thaiv corrosion.
Cov pa roj carbon 50 lossis ntau dua yog cov hlau, yog li 50 cr15mov los ua ib rab riam thiab cov dej ntws ntawm cov riam steel.
Cov ntsiab lus carbon yog ntau tshaj 50, vim lub siab hardness, hniav yog ib qho yooj yim rau tawg, thiaj li yuav daws tau qhov teeb meem no feem ntau yog ua nrog steel riam, raws li lub npe implies, nruab nrab ib feem steel reinforced nrog siab zog (
High carbon siab chromium)
Cov khoom siv rau cov niam txiv hlau, ob sab siv cov khoom siv qis carbon nrog zoo toughness, los ntawm kev kub siab sib xyaw ntau lawm.
70 cr17, 80 cr17: sanhe steel steel reinforced khoom, riam hauv tsev ntawm cov khoom siv high-end, sib tsoo siv tau ntev rau ib lub sijhawm.
90 cr18, 90 cr18mov, VG10: cov ntaub ntawv hauv tsev riam sab saum toj, thiab steel series, piv rau zwilling kojiro, pas nrig, pom ntawm cov riam high-end hauv riam.
Neff) tsom mus rau cov cuab yeej tsim khoom, muab ntau yam cuab yeej txiav high-end hauv kev cai, ntau hom, kev ruaj ntseg zoo.
