ASTM A213 T22, tseem hu ua ASME SA213 T22, yog cov yeeb nkab hlau tsis muaj hlau uas tsis muaj hlau ntau nrog 1.90–2.60% chromium thiab 0.87–1.13% molybdenum ua cov khoom tseem ceeb, feem ntau siv rau hauv boilers, superheaters, thiab cov cua sov sib pauv hauv qhov kub thiab txias, qhov chaw siab.
Lub npe UNS yog K21590.
Botop Hlauyog ib tus kws tshaj lij thiab txhim khu kev qha alloy steel yeeb nkab xa khoom thiab stockist hauv Suav teb, muaj peev xwm sai sai muab cov yeeb nkab zoo alloy steel rau koj cov haujlwm.
Txhua yam khoom txhawb nqa kev tshuaj xyuas los ntawm cov neeg thib peb, thiab peb kuj tuaj yeem muab cov khoom sib xyaw ua ke xws li lub luj tshib thiab lwm yam khoom siv yeeb nkab.
Cov kav hlau T22 yuav tsum ua los ntawmcov txheej txheem tsis muaj teeb meemthiab yuav tsum yog kub tiav los yog txias tiav, raws li tau teev tseg.
Txhua lub kav hlau T22 yuav tsum tau rov ua kom sov rau kev kho cua sov, uas yuav tsum tau ua cais thiab ntxiv rau kev ua kom sov rau kev tsim kub.
Cov txheej txheem kho cua sov uas tau tso cai yog tag nrho lossis isothermal annealing, lossis normalize thiab temper.

Ntxiv mus, cov khoom siv kho tshuab ntawm ASTM A213 T22 zoo ib yam li cov ntawm T2, T5, T5c,T11, T17, thiab T21.
ASTM A213 T22 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.
Yog lawm, yog tias koj qhov project xav tau lwm qhov loj me, qhov ntawd kuj raug tso cai, tsuav yog ua tau raws li tag nrho lwm yam kev cai hauv ASTM A213.
Cov kev cai ntawm kev kam rau siab ntawm ASTM A213 yog tib yam thiab tau teev tseg rauT11 cov yeeb nkab hlauKoj tuaj yeem nyem kom pom lawv yog tias xav tau.
ASTM A213 T22 cov kav hlau tsis muaj seamless siv dav hauv qhov kub thiab txias thiab siab siab, tshwj xeeb tshaj yog hauv kev tsim hluav taws xob, petrochemical, thiab roj & roj lag luam.
Cov ntawv thov ib txwm muaj xws li:
Cov raj boilersiv rau cov superheaters, reheaters, thiab economizers hauv cov chaw tsim hluav taws xob.
