Hauv ASTM A213, ntxiv rau qhov yuav tsum tau ua rau cov khoom tensile thiab qhov nyuaj, cov kev ntsuam xyuas hauv qab no kuj tseem yuav tsum tau ua: Kev Ntsuas Flattening thiab Kev Ntsuas Flaring.
ASTM A213 T11(ASME SA213 T11) yog cov hlau tsis tshua muaj hlauseamless hlau rajmuaj 1.00–1.50% Cr thiab 0.44–0.65% Mo, nrog cov khoom tiv taus cua sov zoo heev, tsim nyog rau kev siv kub thiab siab.
T11 feem ntau siv rau hauvcov boiler, cov superheaters, thiab cov hloov pauv cua sov.UNS tus lej: K11597.
Chaw Tsim Khoom thiab Mob
ASTM A213 T11 cov kav hlau yuav tsum ua los ntawm cov txheej txheem seamless thiab yuav tsum yog kub tiav lossis txias tiav, raws li tau teev tseg.
Kev Kho Mob Kub
Cov kav hlau T11 yuav tsum tau rov ua kom sov rau kev kho cua sov raws li cov txheej txheem hauv qab no, thiab kev kho cua sov yuav tsum tau ua cais thiab ntxiv rau kev ua kom sov rau kev tsim kub.

Qhov Ntev Ntau Yam
ASTM A213 T11 cov yeeb nkab loj thiab phab ntsa tuab feem ntau yog muab nrog sab hauv txoj kab uas hla txij li 3.2 hli mus rau sab nraud txoj kab uas hla ntawm 127 hli, thiab qhov tsawg kawg nkaus phab ntsa tuab ntawm 0.4 hli mus rau 12.7 hli.
Lwm qhov loj ntawm T11 steel kav dej kuj tseem tuaj yeem muab tau, muab tias txhua yam kev cai ntawm ASTM A213 tau ua tiav.
Kev kam rau siab ntawm phab ntsa
Qhov kev kam rau siab ntawm phab ntsa yuav tsum tau txiav txim siab raws li ob qho xwm txheej hauv qab no: seb qhov kev txiav txim puas tau teev tseg raws li qhov tsawg kawg nkaus ntawm phab ntsa lossis qhov nruab nrab ntawm phab ntsa.
1.Qhov tsawg kawg nkaus ntawm phab ntsa tuabNws yuav tsum ua raws li cov kev cai ntawm Tshooj 9 ntawm ASTM A1016.
