I-ASTM A283 Iphepha lentsimbi yeCarbon

I-ASTM A283 ipleyiti yentsimbi ibonakalisa amandla aphantsi kwaye aphakathi amandla entsimbi yekhabhoni yomgangatho wolwakhiwo. Ineendlela ezine eziqhelekileyo, nganye imelwe njengesixhobo esahlukileyo. Icandelo leempawu zezinto ezingezantsi libonisa uluhlu olubandakanya zonke iintlobo ezahlukeneyo.

Le nkcazo ihlanganisa amabakala amane eepleyiti zensimbi zekhabhoni zomgangatho wesakhiwo sokusetyenziswa ngokubanzi. Iisampulu zentsimbi ziya kunyibilikiswa mhlawumbi nge-open-heartth, i-basic-oxygen, okanye iziko lombane. Uhlalutyo lobushushu kunye nemveliso luya kwenziwa apho imathiriyeli yentsimbi iya kuhambelana neekhemikhali ezifunekayo zekhabhoni, imanganese, iphosphorus, isulfure, isilicon kunye nobhedu. Iisampulu zentsimbi nazo ziya kungena kuvavanyo lwe-tensile kwaye ziya kuhambelana neenqobo ezifunekayo zamandla okuqina, indawo yesivuno, kunye nobude.
