ASTM A213 T5(ASME SA213 T5) yog ib lub raj hlau tsis muaj hlau uas muaj 4.00–6.00% chromium (Cr) thiab 0.45–0.65% molybdenum (Mo), muab lub zog kub zoo heev thiab tiv taus corrosion, thiab feem ntau yog siv rau hauv cov khoom siv kub thiab siab xws li boilers, superheaters, thiab cov khoom siv hloov pauv cua sov.
Lub npe UNS yog K41545.
Hauv ASTM A213 tus qauv, ntxiv rau T5, cov hlau alloys nrog tib cov ntsiab lus chromium thiab molybdenum suav nrog T5b (UNS K51545) thiab T5c (UNS K41245), tsuas yog txawv me ntsis hauv cov ntsiab lus ntawm carbon, silicon, thiab lwm yam ntsiab lus.
Botop Steel yog tus kws tshaj lij thiab txhim khu kev qha alloy steel yeeb nkab stockist thiab wholesaler hauv Suav teb, muaj peev xwm sai sai muab koj cov haujlwm nrog ntau qib ntawm alloy steel yeeb nkab, suav nrogT9 (K90941),T11 (K11597),T12 (K11562),T22 (K21590), thiabT91 (K90901).
Peb cov khoom muaj kev ntseeg siab zoo, tus nqi sib tw, thiab txhawb nqa kev tshuaj xyuas los ntawm lwm tus neeg.

Chaw Tsim Khoom thiab Mob
ASTM A213 T5 cov kav hlau 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.
Kev Kho Mob Kub
Cov kav hlau T5 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.

Qee cov hlau yuav tawv thaum cua txias hauv huab cua los ntawm qhov kub siab, tshwj xeeb tshaj yog cov hlau uas muaj chromium nrog chromium ntawm 4% thiab siab dua. Yog li ntawd, kev ua haujlwm uas cuam tshuam nrog kev ua kom sov cov hlau no siab dua lawv qhov kub tseem ceeb, xws li kev vuam, kev sib txuas, thiab kev khoov kub, yuav tsum tau ua raws li kev kho cua sov kom haum.
Qhov tsos
ASTM A213 ferritic alloy txias-ua tiav cov kav hlau yuav tsum tsis muaj nplai thiab tsim nyog rau kev tshuaj xyuas. Me ntsis ntawm oxidation tsis suav tias yog nplai.
Cov kav hlau ua los ntawm Ferritic alloy kub-tiav yuav tsum tsis muaj qhov xoob xoob thiab tsim nyog rau kev tshuaj xyuas.
