1. ** Dab tsi yog t9 khoom? **
T9 yog ib tug ** chromium-molybdenum alloy steel ** uas tsim los ntawm ASME. Nws cov yam ntxwv tseem ceeb yog nws cov lus xyaw: kwv yees li ** 9% chromium (CR) thiab 1% Molybdenum (mo) **. Nws muaj qhov yooj yim dua qhov siab kub-zog, thiab oxidation tsis kam piv rau cov hlau txo qis xws li T11 lossis T12.
2. ** Dab tsi yog T9 siv rau? **
T9 feem ntau yog siv rau kev tsim qauv ** Tshaj tawm ** Tshaj tawm cov khoom siv hluav taws xob "ntawm pob zeb loj ** Nws lub hom phiaj tseem ceeb yog los tiv thaiv cov pa hluav taws kub siab thiab nce mus txog ~ 593 degree tsim kev txwv) tsis muaj kev cuam tshuam ntau (nkag) lossis oxidation.
3. ** Dab tsi yog A213 T9 khoom? **
Sa -213 T9 (feem ntau sau ua A213 T9) yog hais txog qhov ** Rho tawm los ntawm ** Lub "T9" qhia txog cov khoom kawm qib hauv cov qauv no. Nws yuam kev cov tshuaj lom neeg muaj pes tsawg leeg (9Cr -1 mo} mo} mo) thiab cov neeg kho tshuab xav tau rau cov hlua T9 ua kom muaj kev siv tshuab hluav taws xob siab.
4. ** T12 cov khoom siv li cas? **
T12 yog ib tug ** chromium-molybdenum alloy steel ** tsim los ntawm ASME. Nws cov yam ntxwv tseem ceeb yog nws cov cim: kwv yees li ** 1.25% chromium (cr) {}}. 50% Nws muab tau zoo dua kub lub zog thiab oxidation tiv taus dua li cov hlau hlau tab sis tsawg dua li cov alloys zoo li T9 lossis T91. Nws yog cov laus dua, feem ntau siv cov qib hnub no.
5. ** Dab tsi yog qhov ntsuas kub rau sa213 t12? **
** ** Qhov kev tso cai tshaj plaws uas tau tso cai pub kub ** rau sa {0}} t mieces boiler thiab siab i (lub zog boilers), yog ** 1000 degree f (538 degree) **. Qhov no yog qhov txwv kev txwv siab rau kev suav cov kev ntxhov siab uas muaj kev ntxhov siab hauv lub siab. Kev ua haujlwm tiag tiag kub yuav qis qis nyob ntawm cov kev pabcuam tshwj xeeb, nias, thiab xav tau lub neej. Nws yog feem ntau siv rau qis-kub supildeater \/ cov ntawv thov maj mam piv rau qib zoo li T22 lossis T9.
