A252 Qeb 3 Hlau Yeeb Nkab Rau Cov Kav Dej
Nyob rau hauv lub ntiaj teb no ntawm engineering tsim thiab kev tsim kho, muaj txhim khu kev qha thiab ntau yam steel kav yog ib qho tseem ceeb heev.A252 GRADE 3 steel yeeb nkab haum rau qhov kev piav qhia zoo kawg nkaus, ua rau nws yog ib qho ntawm cov yeeb nkab feem ntau siv thoob plaws kev lag luam.Nrog nws lub zog zoo tshaj plaws thiab kev tiv thaiv corrosion, cov yeeb nkab steel no yog coj los ua ib qho kev hloov pauv tsis tau pom dua rau kev tsim cov kav dej.
A252 Qib 3 steel yeeb nkabyog paub txog nws superior tensile zog, tshaj lwm yam steel yeeb nkab.Nws muaj ntau dua tensile thiab compressive tsis kam, ua kom muaj kev ruaj ntseg zoo heev.Cov cwj pwm no dhau los ua qhov tseem ceeb tshwj xeeb tshaj yog qhov uas cov kav dej phwj tuaj yeem raug thauj khoom loj kom ntseeg tau tias kev ua tau zoo thiab kav ntev.Cov kws tshaj lij hauv engineering tuaj yeem ntseeg cov yeeb nkab steel no kom tiv taus cov xwm txheej hnyav.
Lwm qhov tshwj xeeb ntawm A252 Qib 3 steel yeeb nkab yog nws txoj kev kho saum npoo.Txhawm rau ua kom zoo tshaj plaws, cov kav dej tau raug kho kom zoo los tiv thaiv oxidation thiab corrosion.Qhov no txhais tau hais tias cov yeeb nkab tuaj yeem ua haujlwm nyob rau hauv ib puag ncig corrosive heev xws li dej hiav txwv, swamps thiab tshuaj nroj tsuag yam tsis muaj kev cuam tshuam nws qhov kev ua tau zoo.Lub robustness ntawm cov yeeb nkab nto ua rau nws xaiv zoo heev rau tej yaam num uas yuav tsum tau superior corrosion kuj.
