GB/T 3077 30Mn2 Alloy Steel Phaj
Oct 11, 2022
GB/T 3077 30Mn2 alloy steel phaj yog cov khoom siv zoo kawg nkaus nrog tus tswv tsev ntawm cov yam ntxwv zoo heev.
No alloy steel phaj yog renowned rau nws zoo heev mechanical zog. Nws muaj lub zog tensile siab, ua rau nws tiv taus qhov hnyav thiab kev ntxhov siab. Lub zog tawm los ntawm 30Mn2 phaj kuj tseem ceeb, kom ntseeg tau tias nws tsis deform yooj yim nyob rau hauv siab. Qhov no ua rau nws tsim nyog rau kev siv ntau yam kev lag luam xws li kev tsim kho, tshuab tsim, thiab tsheb.
Ntxiv nrog rau lub zog, qhov no alloy steel phaj muaj zoo hardness thiab hnav tsis kam. Nws tuaj yeem tiv taus kev puas tsuaj thiab deformation, ua rau nws zoo tagnrho 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 GB / T 3077 30Mn2 alloy steel phaj yog ua tib zoo tsim kom ua tiav cov khoom tsim nyog. Nws feem ntau muaj cov ntsiab lus xws li manganese (Mn), carbon (C), thiab lwm yam alloying ntsiab. Cov ntsiab lus ntawm manganese pab txhawb rau cov hlau lub zog thiab toughness, thaum cov carbon muab hardness.
Kev tsim cov txheej txheem ntawm cov hlau hlau phaj no suav nrog kev tswj xyuas meej ntawm 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 du nto tiav.
GB/T 3077 30Mn2 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 cov hardness thiab lub zog ntawm cov hlau.
Hauv kev xaus, GB / T 3077 30Mn2 alloy steel phaj yog cov khoom siv ua haujlwm siab nrog cov khoom siv zoo heev, hardness, hnav tsis kam, thiab toughness. Nws cov yam ntxwv tshwj xeeb ua rau nws muaj txiaj ntsig zoo rau kev siv ntau yam hauv kev lag luam sib txawv. Txawm hais tias nws yog rau cov khoom siv, cov khoom siv, lossis cov cuab yeej siv, cov phaj hlau no muaj kev ua tau zoo thiab ua haujlwm ntev.
