DIN 1.2581 H21 Kub Ua Haujlwm Cuab Yeej Hlau

DIN 1.2581 H21 Cov Cuab Yeej Kub Ua Haujlwm Hlau yog cov khoom siv zoo heev hauv cov cuab yeej ua haujlwm kub. Qib steel no paub txog nws cov khoom tshwj xeeb uas ua rau nws tsim nyog rau ntau yam kev thov.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm DIN 1.2581 H21 yog nws cov cua sov zoo heev. Nws tuaj yeem tiv taus qhov kub thiab txias tsis tas yuav poob nws cov khoom siv kho tshuab, ua rau nws zoo tagnrho rau kev siv hauv cov txheej txheem kub kub xws li tuag casting, forging, thiab extrusion. Cov hlau muaj peev xwm tswj tau nws qhov hardness thiab lub zog ntawm qhov kub siab ua kom lub neej ntev thiab txhim khu kev qha.

Ntxiv nrog rau qhov kub tsis kam, DIN 1.2581 H21 kuj pom zoo toughness. Qhov no tso cai rau nws nqus qhov cuam tshuam thiab poob siab loads yam tsis muaj kev tawg, muab kev txhim kho durability thiab kev ntseeg siab hauv kev xav tau kev ua haujlwm. Kev sib xyaw ua ke ntawm lub zog siab thiab lub zog ua rau cov qib steel no yog qhov kev xaiv zoo tshaj plaws rau cov cuab yeej uas raug hnyav hnyav thiab rov ua dua.

Lwm tus yam ntxwv tseem ceeb ntawm DIN 1.2581 H21 yog nws hnav tsis kam. Cov hlau lub microstructure thiab alloying ntsiab muab nws lub peev xwm los tiv thaiv puas thiab yaig, ua kom lub neej ntev kev pab cuam rau cov cuab yeej ua los ntawm cov khoom no. Qhov kev hnav tsis kam no yog qhov tseem ceeb hauv cov ntawv thov ua haujlwm kub qhov twg cov cuab yeej sib txuas tas li nrog cov hlau kub lossis lwm yam khoom siv abrasive.

DIN 1.2581 H21 kuj muaj kev ua haujlwm zoo, uas yooj yim rau kev tsim khoom. Nws tuaj yeem raug siv los siv cov cuab yeej txiav thiab cov txheej txheem, txawm hais tias xaiv cov cuab yeej tsim nyog thiab kev ua haujlwm tsis zoo yog qhov tsim nyog kom ua tiav cov txiaj ntsig zoo. Qhov no machinability factor pab txo cov nqi tsim khoom thiab lub sijhawm ua haujlwm.

Tsis tas li ntawd, DIN 1.2581 H21 tuaj yeem kho cua sov kom zoo rau nws cov khoom. Cov txheej txheem kho cua sov xws li quenching thiab tempering tuaj yeem ua rau cov hlau hardness, lub zog, thiab toughness, thaum tseem txhim kho nws qhov kev ruaj ntseg. Cov txheej txheem kev kho cua sov yuav tsum tau ua tib zoo tswj kom ntseeg tau tias cov khoom xav tau tiav.

Ntxiv rau nws cov khoom siv kho tshuab, DIN 1.2581 H21 kuj muaj qhov zoo corrosion kuj. Txawm hais tias nws yuav tsis zoo li corrosion-resistant li qee cov hlau tsis muaj steel, nws tseem muaj qee theem ntawm kev tiv thaiv me me corrosive ib puag ncig. Qhov no tuaj yeem tau txais txiaj ntsig zoo hauv cov ntawv thov uas lub cuab yeej tuaj yeem raug ya raws, roj, lossis lwm yam khoom siv corrosive.

Ntxiv mus, DIN 1.2581 H21 muaj kev ruaj ntseg zoo heev. Qhov no txhais tau hais tias nws tuav nws cov duab thiab qhov loj me txawm tias thaum raug kub thiab kho tshuab. Cov cuab yeej no yog qhov tseem ceeb rau cov ntawv thov uas qhov tseeb yog qhov tseem ceeb, xws li hauv kev tsim cov pwm thiab tuag.

Hauv kev xaus, DIN 1.2581 H21 Cov Khoom Kub Kub Ua Haujlwm Hlau yog cov khoom siv zoo kawg nkaus uas muaj kev sib xyaw ua ke ntawm cov khoom zoo heev rau kev siv ua haujlwm kub. Nws cov cua kub tsis kam, toughness, hnav tsis kam, machinability, corrosion kuj, thiab seem stability ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau ntau yam kev xav tau kev lag luam. Txawm hais tias nws tau siv hauv kev tuag casting, forging, extrusion, lossis lwm yam kev siv kub ua haujlwm, DIN 1.2581 H21 muab kev ua tau zoo thiab kev ua haujlwm ntev. Nrog rau kev kho cua sov kom zoo thiab cov txheej txheem tsim khoom, qib steel no tuaj yeem ua tau raws li qhov xav tau ntawm cov cuab yeej kub ua haujlwm.
