JIS G 4104-1979 SCr445 thiab SCr5: Kev Tshawb Fawb Kom Paub
Japanese Industrial Standard JIS G 4104-1979 txhais ob qho tseem ceeb alloy steels, xws li SCr445 thiab SCr5. Cov hlau no ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam vim lawv cov khoom tshwj xeeb thiab cov yam ntxwv.
SCr445 yog chromium alloy hlau uas muaj cov khoom siv kho tshuab zoo heev. Nws muaj lub zog tensile siab thiab hardness, ua rau nws haum rau cov ntawv thov uas yuav tsum tau ua kom muaj zog thiab tsis kam hnav. Qhov sib ntxiv ntawm chromium txhim kho nws cov corrosion kuj, tso cai rau nws siv nyob rau hauv ib puag ncig uas raug rau ya raws thiab lwm yam corrosive ntsiab yog ib qho kev txhawj xeeb. SCr445 kuj muaj cov machinability zoo, ua rau nws yooj yim fabricated rau ntau yam duab thiab ntau thiab tsawg.
Ntawm qhov tod tes, SCr5 yog lwm cov chromium alloy steel nrog nws tus kheej cov khoom tsim nyog. Nws muaj cov tshuaj sib txawv me ntsis piv rau SCr445, uas muab nws cov khoom siv kho tshuab thiab lub cev tshwj xeeb. SCr5 tuaj yeem muaj qhov sib txawv hardness, tensile zog, thiab ductility, nyob ntawm seb cov kev cai tshwj xeeb ntawm daim ntawv thov. Nws kuj tseem paub txog nws txoj kev kho cua sov zoo, tso cai rau kev hloov kho ntawm nws cov khoom los ntawm cov txheej txheem xws li quenching thiab tempering.
Ob leeg SCr445 thiab SCr5 tau siv dav hauv kev lag luam xws li tsheb, tshuab tsim, thiab engineering. Hauv kev lag luam tsheb, lawv tau siv rau cov khoom xws li lub zog, ncej, thiab cov kabmob, qhov twg lub zog thiab kav ntev yog qhov tseem ceeb. Hauv kev tsim cov tshuab, lawv tau ua haujlwm hauv kev tsim cov cuab yeej thiab tuag uas yuav tsum tau tiv taus kev ntxhov siab thiab hnav. Hauv kev siv engineering, cov hlau no yog siv rau cov khoom siv uas xav tau lub zog thiab ruaj khov.
JIS G 4104-1979 tus qauv muab cov lus qhia ntxaws ntxaws rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov txheej txheem tsim khoom ntawm SCr445 thiab SCr5. Qhov no ua kom zoo ib yam thiab kev ua tau zoo ntawm cov tuam ntxhab sib txawv thiab cov khoom tsim khoom. Cov neeg tsim khoom yuav tsum ua raws li cov qauv no kom ntseeg tau tias cov hlau ua tau raws li qhov xav tau tshwj xeeb rau lawv cov ntawv thov.
Hauv kev xaus, JIS G 4104-1979 tus qauv rau SCr445 thiab SCr5 txhais ob qho tseem ceeb alloy steels nrog cov khoom tshwj xeeb thiab kev siv. Cov hlau no muaj cov khoom siv zoo heev, kev tiv thaiv corrosion, thiab machinability, ua rau lawv cov khoom tseem ceeb hauv ntau yam lag luam. Los ntawm kev ua raws li tus qauv, cov tuam txhab tsim khoom tuaj yeem ua kom zoo thiab ua haujlwm ntawm cov hlau no, muab cov kev daws teeb meem txhim khu kev qha rau kev sib txawv engineering thiab kev tsim khoom.
