ASTM A213 T12(ASME SA213 T12) yog cov yeeb nkab uas tsis tshua muaj hlau tsis zoo uas tsim los rau kev pabcuam kub.
Nws cov ntsiab lus tseem ceeb yog 0.80-1.25% chromium thiab 0.44-0.65% molybdenum, uas cais nws raws li chromium-molybdenum alloy hlau. Nws yog dav siv nyob rau hauv high-temperature thiab high-pressure ib puag ncig xws li boilers, superheaters, thiab tshav kub exchangers.
T12 yeeb nkab muaj qhov tsawg kawg nkaus tensile zog ntawm 415 MPa thiab qhov tsawg kawg nkaus yield zog ntawm 220 MPa.
UNS lub npe rau qib no yog K11562.
Botop Steel yog ib tug kws tshaj lij thiab txhim khu kev qha alloy steel yeeb nkab stockist thiab wholesaler nyob rau hauv Suav teb, muaj peev xwm muab tau sai sai rau koj tej yaam num nrog ntau qib ntawm alloy steel kav, nrog rauT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590), thiabT91 (K90901).
Peb cov khoom muaj kev ntseeg siab zoo, tus nqi sib tw, thiab txhawb kev soj ntsuam thib peb.

Chaw tsim tshuaj paus thiab tej yam kev mob
ASTM A213 T12 steel kav yuav tsum tau ua los ntawm cov txheej txheem seamless thiab yuav tsum yog kub tiav lossis txias tiav, raws li tau teev tseg.
Kev kho cua sov
Txhua T12 steel kav yuav tsum tau kho cua sov.
Tso cai rau kev kho cua sov xws li full los yog isothermal annealing, normalizing thiab tempering, los yogsubcritical annealing.

Txhua lub raj yuav tsum raug kuaj xyuas hluav taws xob tsis muaj kev puas tsuaj lossis kev sim hydrostatic.Hom kev xeem uas yuav tsum tau siv yuav tsum nyob ntawm qhov kev xaiv ntawm cov chaw tsim khoom, tshwj tsis yog tias muaj lwm yam teev nyob rau hauv daim ntawv xaj khoom.
Cov kev sim yuav tsum tau ua raws li cov kev cai ntawm Tshooj 25 thiab 26 ntawm ASTM A1016.
ASTM A213 T12 tubing qhov ntau thiab tsawg thiab phab ntsa thicknesses feem ntau yog rooj tog nrog cov kab uas hla ntawm 3.2 hli mus rau sab nraud diameters ntawm 127 hli, thiab qhov tsawg kawg nkaus phab ntsa thickness ntawm 0.4 hli mus rau 12.7 hli.
Lwm qhov ntau thiab tsawg ntawm T12 steel kav kuj tuaj yeem muab tau, yog tias tag nrho lwm cov kev cai ntawm ASTM A213 tau ntsib.
ASTM A213 T12 alloy steel seamless hlab yog feem ntau siv nyob rau hauv high-temperature thiab high-pressure kev pab cuam ib puag ncig. Cov ntawv thov ib txwm suav nrog
1. Superheaters thiab Reheaters
Siv nyob rau hauv fais fab nroj tsuag rau superheater thiab reheater hlab ua hauj lwm nyob rau hauv siab kub thiab siab.
2. Boiler Tubes
Siv dav hauv boiler raj hauv thermal fais fab chaw nres tsheb, khib nyiab-kub rov qab units, thiab muaj boilers.
3. Thaum tshav kub kub Exchangers
Haum rau tshav kub exchanger tubing nyob rau hauv petrochemical thiab tshuaj industries vim nws zoo creep kuj thiab thermal stability.
4. Lub qhov cub thiab lub rhaub dej kub
Nruab nyob rau hauv refinery furnace coils, rhaub tubing, thiab cov txheej txheem cua sov qhov twg oxidation kuj thiab ntev lub zog yuav tsum tau.
5. Siab Piping hauv fais fab thiab Petrochemical Cog
Siv rau cov kav dej kub kub, nrog rau cov kav dej thiab cov kav dej kub.
