SA-210C carbon steel yeeb nkab yog qib steel hauv ASME SA-210 tus qauv. Nws yog carbon-manganese steel yeeb nkab rau boilers thiab superheaters. Nws yog pearlite-type heat-strength steel.
Nws cov tshuaj muaj pes tsawg leeg yog qhov yooj yim, tshwj tsis yog cov ntsiab lus carbon thiab manganese ntau dua, qhov seem zoo ib yam li 20G, yog li nws lub zog tawm los yog li 20% siab dua 20G, thaum nws cov yas thiab tawv zoo sib npaug rau 20G carbon steel kav.
Cov hlau muaj cov txheej txheem tsim khoom yooj yim thiab ua haujlwm kub thiab txias zoo. Siv nws los hloov 20G steel kav tuaj yeem ua rau nyias phab ntsa tuab, txo cov khoom siv, thiab txhim kho cov cua kub hloov ntawm lub boiler.
Nws qhov chaw siv thiab kev siv kub yog qhov zoo ib yam li cov 20G steel kav. Nws yog tsuas yog siv rau cov phab ntsa dej-txias, cov khoom lag luam, cov cua kub qis thiab lwm yam khoom siv nrog kev ua haujlwm kub hauv qab 500 degree.
