Ntsuas seb puas yog rab riam siv, thawj qhov yuav tsum xav txog yog ntse.
Lub ntse degree ntawm lub ntsiab yam tseem ceeb yog hardness ntawm steel (
硬度)
.
Piv txwv tias muaj ob rab riam, ib qho yog ua los ntawm cov hlau mos, lwm qhov yog ua los ntawm cov hlau tawv.
Sib tsoo lawv ntse heev, seb lawv puas yog tib yam?
Cov lus teb yog tsis muaj, vim hais tias cov mos steel sharpness sai sai.
Yog li pheej ua kom ntse nyob ntawm qhov muaj peev xwm ntawm hardness ntawm steel, yog qhov tseem ceeb uas txiav txim siab qhov kev ua tau zoo ntawm riam.
Ntxiv rau qhov pom kev vam meej rau chav ua noj riam steel hardness thiab corrosion kuj, hnav tsis kam, toughness, hardness thiab toughness yog contradictory, hardness,
Cov ntsiab lus carbon)
Hnav tsis kam thiab corrosion kuj yog feem ntau contradictory, lub caij yuav ua rau chav ua noj ntau kom ntse rau lub sij hawm ntev tab sis nws yuav nyuaj rau zom.
Stainless hlau thiab lwm yam khoom hlau, tsis muaj qhov tseem ceeb sib txawv ntawm tsuas yog vim muaj cov ntsiab lus chromium siab, chrome oxide tsim nyob rau hauv cov hlau nto los tiv thaiv hlau oxide, nyob rau hauv cov ntaub ntawv ntawm cov dej npuas ntev yuav ua rau xeb.
420 series stainless hlau zoo tib yam supermarkets muag tsawg kawg chav ua noj riam yog ntau lub hom phiaj, pheej yig thiab zoo heev xeb kuj, tab sis cov ntsiab lus ntawm cov pa roj carbon tsawg tsawg, yog li tsis tshua muaj hardness yog tsis ntau tshaj 52, roughly sib npaug rau peb domestic low-end feem ntau siv. peb chrome steel (
Tus nqi hais txog cov ntsiab lus carbon ntawm tus lej dhau los ib lab)
.
X50CrMoV15 ashkenazi mainstream steel chav ua noj riam, zoo xeb kuj, toughness, tab sis blunt ceev.
Tab sis kev saib xyuas zoo tsis tuaj yeem txiav lub cev qhuav dej, kwv yees sib npaug rau peb lub tsev siv 5 chrome steel riam.
Tau kawg 5 chrome steel kev ua tau zoo dua li cov hlau zoo tib yam nws tus kheej, tom qab cov chaw tsim khoom tshwj xeeb kev kho cua sov kuj muaj qee yam kev nce qib, tab sis cov khoom xyaw muaj kev ua tau zoo.
Lub tsev muaj ib tug zoo xws li hardness steel chav ua noj riam siv los txiav cov tuab tav, dawb txiav nqaij qaib, chop chop dab tsi nqaij npuas yog zoo heev, tab sis txiav zaub nqaij yuav pom tseeb zoo li Japanese hlau.
Japanese chav ua noj riam yam tsis muaj cov hlau, ntawm no tsuas yog rau lub hom phiaj ntawm qhov sib txawv.
Molybdenum vanadium stainless hlau (
AUS-
8)
Hardness yog qis dua 58, qee qhov nkag-theem chav ua noj riam siv nyob rau hauv Nyiv, lub domestic yim chrome hlau, chrome steel 9 zoo sib xws hardness.
VG -
10 Nyiv 'kuv lub tuam txhab steel tshwj xeeb hauv kev tsim cov khoom siv high-end stainless hlau, yog muaj nyob rau hauv Japanese chav ua noj riam, nws kuj yog heev haum rau tus kheej-tseem ceeb.
Ua kom cov qib ntse zoo, hardness siab, kuj tsis yooj yim rau xeb, tab sis siab carbon cov ntsiab lus tsawg dua 5 chrome steel xeb kuj.
Muaj qhov xwm txheej yuav luag me ntsis qis-kawg VG1 steel, hardness, txog 60.
Molybdenum vanadium stainless hlau (
AUS-
8)
Hardness yog qis dua 58, qee qhov nkag-theem chav ua noj riam siv nyob rau hauv Nyiv, lub domestic yim chrome hlau, chrome steel 9 zoo sib xws hardness.
Hmoov hlau hmoov metallurgy (
粉末冶金)
Yog cov khoom ntawm niaj hnub metallurgical technology, yog ib hom hlau hmoov raws li raw khoom, los ntawm nias thiab sintering txheej txheem ntawm ntau yam khoom.
Vim hais tias hmoov hlau thoob ntiaj teb cov khoom tsim tawm txhua xyoo tsuas yog tsib caug txhiab tons, nrog rau kev siv tshuab los ua tus tswv nyuaj tsuas yog ib txhais tes ntawm cov tuam txhab tsim khoom, siab tshaj tus nqi ntawm chav kawm.
