Hauv phau ntawv qhia no, peb rhuav tshem cov chemistry, cov khoom, lub zog, qhov tsis muaj zog, thiab kev siv zoo tshaj plaws ntawm 420 thiab 440 steel los pab koj txiav txim siab.
Dab tsi yog 420 Stainless Hlau?
420 stainless hlau yog aqis-rau- nruab nrab carbon martensitic stainless hlauthiab ib qho ntawm cov peev nyiaj tshaj plaws - cov qib stainless hlau phooj ywg muaj. Nws yog feem ntau hu ua " cutlery-grade stainless" vim nws siv dav hauv riam, cuab yeej, thiab dav dav - lub hom phiaj qhov chaw.
Cov yam ntxwv tseem ceeb ntawm 420 steel:
- Cov ntsiab lus carbon: ~ 0.15-0.25%
- Chromium cov ntsiab lus: ~ 12-14%
- Nruab nrab hardness tom qab kev kho cua sov
- Zoo machinability rau CNC tig, milling, thiab stamping
- Basic corrosion kuj
- Tus nqi qis dua 440 series
- Yooj yim kom ntse thiab tsim
420 steel yog tsim los rau cov kev siv dav dav uas yuav tsum tau muaj kev tiv thaiv corrosion thiab ua haujlwm ntev, tab sis qhov hnyav hnyav lossis hnav tsis kam tsis yog qhov tseem ceeb. Nws yog dav siv nyob rau hauv niaj hnub cov cuab yeej, mechanical fittings, brackets, thiab tsawg - cutlery nqi.
Dab tsi yog 440 Stainless Hlau?
440 stainless hlau yog asiab dua -carbon martensitic stainless hlauua nyob rau hauv ob peb variants: 440A, 440B, thiab 440C. Ntawm cov no, 440C yog qhov ntau tshaj plaws thiab siab tshaj - ua haujlwm, nrog cov pa roj carbon ntau dua li 420 steel.
Cov yam ntxwv tseem ceeb ntawm 440 (tshwj xeeb tshaj yog 440C) steel:
- Cov ntsiab lus carbon: 0.40-1.20% (ntau dua 420)
- Chromium cov ntsiab lus: ~ 16-18%
- Zoo heev hardness thiab hnav tsis kam tom qab kev kho cua sov
- Superior corrosion kuj piv rau 420
- Cov ntug tuav zoo dua rau cov cuab yeej txiav
- Me ntsis nyuaj rau tshuab
- Cov khoom siv ntau dua
440 steel yog tsim los rau siab -qhov ua tau zoo uas xav tau hardness, hnav tsis kam, thiab txhim khu kev tiv thaiv corrosion. Nws yog feem ntau siv nyob rau hauv hwm riam, bearings, li qub, cov cuab yeej phais, thiab precision industrial Cheebtsam.
420 vs 440 Steel: Lub taub hau - mus rau - Lub taub hau sib piv
Txhawm rau kom nkag siab tias cov hlau twg haum rau koj cov kev xav tau, peb muab piv rau lawv hla cov kev ua tau zoo tshaj plaws thiab kev tsim khoom.
1. Hardness & Hnav Resistance
440 steel yog hnyav dua thiab hnav ntau dua -resistant.
Tom qab kev kho cua sov kom zoo, 420 steel feem ntau ncav cuagHRC 50–55, thaum 440C tuaj yeem ua tiavHRC 58–62-ib qib uas tuav cov npoo ntse thiab tiv taus kev puas tsuaj zoo dua. Qhov no ua rau 440 zoo tagnrho rau qhov chaw raug kev sib txhuam, rov siv dua, lossis txiav kev xav tau . 420 yog softer thiab yuav hnav sai dua nyob rau hauv kev siv hnyav, tab sis nws tsis nkig thiab tsis tshua muaj kev cuam tshuam hauv lub teeb.
2. Corrosion Resistance
440 steel outperforms 420 nyob rau hauv corrosion kuj.
Nrog cov ntsiab lus chromium siab dua, 440 steel tiv taus cov av noo, av noo, thiab cov tshuaj me me zoo dua li 420. 420 tuaj yeem xeb lossis tarnish hauv ib puag ncig hnyav, thaum 440 tseem nyob ruaj khov hauv marine, zaub mov - ua, thiab chaw sab nraum zoov. Rau cov khoom siv nyob rau hauv cov dej ntub dej lossis corrosive, 440 yog qhov kev xaiv zoo dua.
3. Machinability & CNC ua
420 steel yog yooj yim dua rau tshuab.
Rau cov tuam txhab siv CNC lathes, milling tshuab, los yog hlau stamping cov cuab yeej, 420 qhov qis hardness thiab cov ntsiab lus carbon txhais tau tias txiav nrawm dua, cov cuab yeej siv tsawg dua, thiab cov nqi tsim khoom qis dua. Nws txiav kom huv si, xav tau lub zog tsawg dua, thiab ua haujlwm zoo rau siab - ntim ntau lawm.
440 steel, hnyav dua thiab hnav ntau dua- tiv taus, ua rau muaj kev ntxhov siab ntau dua rau cov cuab yeej txiav. Nws yuav tsum tau noj qeeb qeeb, cov cuab yeej siv tau ntev dua, thiab kev ua haujlwm ceev faj kom tsis txhob muaj cov cuab yeej tawg lossis ua kom tsis zoo. NtawmJoyear Hlau ua haujlwm, peb pab neeg CNC machining muaj kev paub txog kev ua kom tsis zoo rau ob qib, kom ntseeg tau qhov tseeb txawm tias tawv 440 steel.
4. Nqi & Muaj
420 steel yog pheej yig dua thiab dav muaj.
Cov ntsiab lus qis dua thiab cov khoom siv yooj yim ua rau 420 cov peev nyiaj -kev xaiv tus phooj ywg. 440 steel nqi ntau dua vim cov pa roj carbon ntau dua thiab chromium, nrog rau cov cua sov ntau dua - cov kev kho mob. Rau qhov loj - nplai, tus nqi- cov haujlwm tseem ceeb, 420 feem ntau muab tus nqi zoo tshaj.
5. Ntug tuav & ntse
440 steel tuav ib tug ntse ntug ntev ntev.
Qhov no yog vim li cas 440C yog qhov nyiam rau cov riam zoo tshaj plaws thiab cov cuab yeej txiav . 420 tuav lub ntug yooj yim tab sis dulls sai dua thiab yuav tsum tau ua kom nrawm dua. Thaum 420 yooj yim dua los ua kom ntse, 440 qhov ntev - lub sij hawm tuav tuav ua rau nws zoo tshaj rau kev txiav daim ntawv thov.
Thaum twg Koj Yuav Tsum Xaiv 420 Steel?
420 stainless hlau yog qhov kev xaiv zoo dua thaum:
- Koj xav tau tus nqi qis -tus nqi, dav dav- lub hom phiaj stainless hlau
