TS EN 1.7228 (50CrMo4) Chromium-Molybdenum Hlau
Jul 17, 2023
Khoom Description
TS EN 1.7228, tseem hu ua 50CrMo4 chromium-molybdenum steel, yog cov khoom siv zoo kawg nkaus nrog cov tswv ntawm cov yam ntxwv zoo heev.
Cov hlau no yog tus cwj pwm los ntawm nws cov tshuaj muaj pes tsawg leeg. Nws muaj chromium thiab molybdenum nyob rau hauv zoo-txhais proportions, nrog rau lwm yam ntsiab. Chromium txhim kho cov hlau corrosion kuj, thaum molybdenum pab txhawb zog thiab hardness.
Hais txog cov khoom siv kho tshuab, EN 1.7228 steel yog qhov zoo heev. Nws muaj qhov tshwj xeeb tensile lub zog, ua kom nws tiv taus cov khoom hnyav thiab kev ntxhov siab. Lub zog tawm los kuj tseem ceeb, kom ntseeg tau tias cov khoom tsis deform yooj yim nyob rau hauv siab. Tsis tas li ntawd, cov hlau no nthuav tawm zoo ductility, cia nws khoov thiab zoo li tus yam tsis muaj kev tawg.
Kev kho cua sov teb ntawm EN 1.7228 yog lwm qhov tseem ceeb. Nws tuaj yeem ua kom tawv thiab tempered kom ua tiav cov qib hardness tshwj xeeb thiab cov khoom siv kho tshuab, ua rau nws haum rau ntau yam kev siv.
Hais txog kev hnav tsis kam, qhov no chromium-molybdenum steel ua tau zoo heev. Nws tuaj yeem tiv taus kev puas tsuaj thiab kev sib txhuam, ua rau nws zoo tagnrho rau cov khoom xws li lub zog, ncej, thiab cov kabmob uas raug rau kev txav mus los thiab kev sib cuag.
Ntxiv mus, EN 1.7228 steel muaj kev qaug zog zoo heev. Nws tuaj yeem tiv taus kev thauj mus los thiab kev thauj mus los yam tsis muaj kev puas tsuaj loj, muab lub neej ua haujlwm ntev hauv kev xav tau.
Lub machinability ntawm cov hlau no kuj zoo heev. Nws tuaj yeem ua tiav siv ntau yam kev siv tshuab, suav nrog kev tig, milling, thiab drilling, kom ua tiav cov duab thiab qhov ntev.
Zuag qhia tag nrho, EN 1.7228 (50CrMo4) chromium-molybdenum steel yog cov khoom siv ntau yam thiab txhim khu kev qha. Nws ua ke ntawm lub zog, hardness, hnav tsis kam, qaug zog, thiab machinability ua rau nws muaj kev xaiv nrov hauv kev lag luam xws li tsheb, tshuab, thiab kev tsim kho.
