ASTM A848 yog hais txog tus qauv kev qhia tshwj xeeb rau cov hlau nplaum uas muaj cov pa roj carbon tsawg. Hauv qab no yog cov khoom tseem ceeb cuam tshuam nrog ASTM A848 cov khoom:
Tshuaj muaj pes tsawg leeg
Nws yog cov hlau tsis muaj cov pa roj carbon tsawg, uas txhais tau tias nws muaj feem pua ntawm cov ntsiab lus carbon tsawg.
Cov tshuaj lom neeg muaj pes tsawg leeg yuav txawv nyob ntawm qib thiab qhov tshwj xeeb, tab sis nws feem ntau suav nrog hlau (Fe) ua lub ntsiab tseem ceeb, nrog cov pa roj carbon me me (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab tejzaum nws muaj lwm yam alloying ntsiab los txhim kho nws cov hlau nplaum thiab txhua yam khoom.
Magnetic Properties
ASTM A848 steel yog tus cwj pwm los ntawm nws cov khoom sib nqus.
Nws nthuav tawm zoo sib nqus permeability thiab saturation magnetization, ua rau nws tsim nyog rau cov ntawv thov uas cov khoom sib nqus yog qhov tseem ceeb.
Mechanical Properties
Tsawg-carbon steel feem ntau muaj qhov zoo ductility thiab toughness.
ASTM A848 steel tej zaum yuav raug rau ntau yam kev ntsuam xyuas kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau muaj zog tensile, yield zog, elongation, thiab tej yam toughness qauv.
Daim ntawv thov
Vim nws cov khoom sib nqus thiab cov khoom siv zoo, ASTM A848 steel feem ntau yog siv rau hauv cov ntawv thov xws li hluav taws xob transformers, generators, motors, thiab lwm yam khoom siv hluav taws xob uas siv cov khoom sib nqus.
Nws kuj tseem siv tau rau hauv lwm qhov kev lag luam uas cov hlau tsis muaj cov pa roj carbon tsawg nrog cov khoom sib nqus tshwj xeeb yog xav tau.
Processing thiab Fabrication
ASTM A848 steel tuaj yeem ua tiav thiab tsim siv ntau yam txuj ci xws li txiav, vuam, sib sau, thiab machining.
Kev saib xyuas kom zoo yuav tsum tau ua thaum vuam kom tsis txhob muaj kev cuam tshuam rau nws cov khoom sib nqus.
Nws tsim nyog sau cia tias cov khoom tshwj xeeb ntawm ASTM A848 cov khoom yuav txawv nyob ntawm qib, qhov tshwj xeeb, thiab cov txheej txheem ua. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau sab laj txog cov qauv thiab cov kev qhia tshwj xeeb rau cov ncauj lus kom ntxaws.
