Ib qho txiaj ntsig tseem ceeb ntawm 30Mn5 steel yog nws lub zog txhua yam. Nws muaj lub zog tensile siab thiab lub zog tawm los, ua rau nws tsim nyog rau cov ntawv thov uas muaj kev ncaj ncees yog qhov tseem ceeb. Lub zog no tso cai rau nws tiv taus cov khoom hnyav thiab kev ntxhov siab yam tsis muaj qhov cuam tshuam loj lossis tsis ua haujlwm.
Ntxiv rau lub zog, 30Mn5 steel kuj pom zoo ductility. Qhov no txhais tau hais tias nws tuaj yeem deformed rau qee yam yam tsis tau tawg lossis tawg. Cov cuab yeej no yog qhov tseem ceeb hauv cov ntawv thov uas cov khoom yuav raug khoov, tsim, lossis lwm yam kev siv tshuab.
Cov ntsiab lus ntawm manganese hauv 30Mn5 steel plays lub luag haujlwm tseem ceeb hauv kev txhim kho nws cov hardenability. Manganese pab txhawb kev tsim ntawm ib qho nyuaj thiab hnav-resistant microstructure thaum cov hlau raug kho cua sov. Qhov no ua rau 30Mn5 steel haum rau cov ntawv thov uas yuav tsum tau hnav thiab puas, xws li hauv cov iav, ncej, thiab tshuab qhov chaw.
Lwm yam khoom tseem ceeb ntawm 30Mn5 steel yog nws cov weldability. Nws tuaj yeem ua tau yooj yim welded siv cov txheej txheem vuam, uas ua rau nws yooj yim rau fabrication thiab kho ua haujlwm. Txawm li cas los xij, cov txheej txheem vuam kom raug thiab kev ceev faj yuav tsum tau ua raws li kom ntseeg tau tias kev ncaj ncees ntawm cov pob qij txha welded.
30Mn5 steel kuj paub txog nws cov machinability zoo. Nws tuaj yeem ua tshuab siv cov cuab yeej machining cov cuab yeej thiab cov tswv yim yam tsis muaj cov cuab yeej siv ntau dhau los yog nyuaj. Qhov no ua rau nws raug nqi thiab ua haujlwm tau zoo los tsim cov khoom thiab cov khoom siv los ntawm cov khoom siv no.
Hais txog kev siv, 30Mn5 steel yog siv dav hauv kev tsim khoom ntawm ntau yam khoom siv thiab cov khoom siv. Nws feem ntau pom muaj nyob rau hauv kev lag luam tsheb rau qhov chaw xws li lub zog, ncej, thiab cov pas nrig txuas. Hauv kev ua liaj ua teb machinery sector, nws yog siv rau cov khoom uas yuav tsum tau tiv taus hnyav loads thiab hnav. Nws kuj yog siv nyob rau hauv kev tsim kho kev lag luam rau structural ntsiab thiab machinery qhov chaw.
Zuag qhia tag nrho, 30Mn5 (1.5066) steel yog cov khoom siv txhim khu kev qha thiab ntau yam nrog cov cuab yeej zoo heev. Nws ua ke ntawm lub zog, ductility, hardenability, weldability, thiab machinability ua rau nws yog ib qho kev xaiv nrov rau ntau yam kev siv. Txawm hais tias nyob rau hauv tsheb, kev ua liaj ua teb, lossis kev tsim kho kev lag luam, 30Mn5 steel tuaj yeem muab kev ua tau zoo thiab ua haujlwm ntev.
