GB/T 3077 15Cr Alloy Steel Phaj
Oct 18, 2022
GB/T 3077 15Cr Alloy Steel Phaj yog cov khoom siv zoo kawg nkaus nrog ntau yam ntawm cov yam ntxwv zoo.
Qhov no alloy steel phaj paub txog nws cov khoom siv kho tshuab zoo heev. Nws muaj lub zog tensile siab, ua rau nws tiv taus cov khoom hnyav thiab kev ntxhov siab. Lub zog tawm los ntawm 15Cr alloy steel phaj kuj tseem ceeb, kom ntseeg tau tias nws tsis deform yooj yim nyob rau hauv siab. Qhov no ua rau nws zoo tagnrho rau kev siv hauv ntau yam kev lag luam xws li kev tsim kho, kev tsim khoom, thiab tsheb.
Ntxiv nrog rau nws lub zog, lub phaj steel no muaj qhov zoo hardness thiab hnav tsis kam. Nws tuaj yeem tiv taus kev puas tsuaj thiab deformation, ua rau nws haum rau qhov chaw uas raug kev sib txhuam thiab kev cuam tshuam. Cov cuab yeej no ua rau nws muaj kev xaiv nrov rau cov khoom xws li iav, ncej, thiab bearings.
Cov tshuaj muaj pes tsawg leeg ntawm 15Cr alloy steel phaj suav nrog chromium thiab lwm yam alloying ntsiab. Chromium txhim khu cov hlau hardness, corrosion kuj, thiab kub kuj. Qhov sib ntxiv ntawm lwm cov ntsiab lus ntxiv txhim kho nws cov khoom siv kho tshuab thiab ua rau nws haum rau cov ntawv thov tshwj xeeb.
Kev tsim cov txheej txheem ntawm 15Cr alloy steel phaj yuav tsum ceev faj tswj cov ntsiab lus alloying, kev kho cua sov, thiab dov. Qhov no xyuas kom meej tias cov phaj muaj ib qho microstructure thiab zoo ib yam. Cov txheej txheem ntau lawm yog siv los ua kom tiav qhov ntev thiab qhov chaw tiav.
15Cr alloy steel phaj tuaj yeem ua tiav los ntawm kev siv tshuab, vuam, thiab kev kho cua sov kom tau raws li cov qauv tsim tshwj xeeb. Nws tuaj yeem raug txiav, drilled, thiab welded los tsim cov duab thiab cov qauv. Cov txheej txheem kho cua sov xws li quenching thiab tempering tuaj yeem siv los kho qhov nyuaj thiab lub zog ntawm lub phaj.
Hauv kev xaus, GB / T 3077 15Cr Alloy Steel Phaj yog cov khoom siv ua haujlwm siab nrog lub zog zoo, hardness, hnav tsis kam, thiab corrosion kuj. Nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig xaiv rau ntau yam kev siv. Txawm hais tias nws yog rau cov khoom siv, cov khoom siv kho tshuab, lossis cov cuab yeej siv, cov phaj hlau no muaj kev ua tau zoo thiab ua haujlwm ntev.
