ASTM A333 Qib 6yog cov khoom siv hlau carbon uas siv rau hauv cryogenic thiab lwm yam kev siv uas xav tau notched toughness. Nws muaj peev xwm siv tau rau hauv qhov chaw qis li -45 ° C (-50 ° F) thiab muaj nyob rau hauv ob qho tib si seamless thiab welded daim ntawv.
ASTM A333 tuaj yeem siv rau hauv ib qhoseamless los yog welded txheej txheem.
Cov txheej txheem yeeb nkab hlau tsis muaj seamless yog muab faib ua qhov kub tiav thiab txias kos. Thiab nws yuav tsum tau cuam tshuam saum toj no lub cim.
Cov kav hlau tsis muaj qhov tsis sib xws yog thawj qhov kev xaiv rau cov chaw ib puag ncig hnyav, cov xwm txheej ntxhov siab, thiab thaum xav tau cov kav hlau tuab heev.
ASTM A333 GR.6 yuav tsum tau kho raws li ib qho ntawm cov hauv qab no los tswj nws cov qauv me me:
● Ua kom sov li qub: Ua kom sov mus txog qhov kub sib npaug tsawg kawg yog 1500 °F [815 °C], tom qab ntawd txias rau hauv huab cua lossis hauv chav txias ntawm lub cub tawg uas tswj hwm huab cua.
● Kev ua kom sov tom qab ua kom sov li qub: Tom qab ua kom sov li qub lawm, nws yuav raug rov ua kom sov mus rau qhov kub uas tsim nyog raws li qhov chaw tsim khoom xav tau.
● Rau cov txheej txheem tsis muaj teeb meem, qhov no tuaj yeem ua tiav los ntawm kev tswj qhov kub ntawm cov haujlwm kub thiab cov haujlwm kub tiav kom qhov kub kawg yog txij li 1550 txog 1750 °F [845 txog 945 °C] thiab tom qab ntawd txias hauv huab cua lossis hauv lub cub tawg uas tswj hwm huab cua los ntawm qhov kub pib tsawg kawg yog 1550 °F [845 °C].
● Kev ua kom sov tom qab tswj tau qhov kub thiab ua tiav kev kho cua sov yuav rov ua kom sov mus rau qhov kub kom raug raws li qhov chaw tsim khoom xav tau.
● Kev Tua thiab Kev Kub: Hloov chaw ntawm ib qho ntawm cov kev kho mob saum toj no, cov raj seamless ntawm Qib 1, 6, thiab 10 yuav raug kho los ntawm kev cua sov kom txog qhov kub sib npaug tsawg kawg yog 1500 ° F [815 ° C], ua raws li kev tua hauv dej thiab rov ua kom sov mus rau qhov kub tempering kom raug.
ARau txhua qhov kev txo qis ntawm 0.01% carbon qis dua 0.30%, kev nce ntawm 0.05% manganese saum 1.06% yuav raug tso cai rau qhov siab tshaj plaws ntawm 1.35% manganese.
CLos ntawm kev pom zoo ntawm tus neeg tsim khoom thiab tus neeg yuav khoom, qhov txwv rau niobium yuav raug nce mus txog 0.05% ntawm kev tshuaj xyuas cua sov thiab 0.06% ntawm kev tshuaj xyuas khoom.
DCov lus Niobium (Nb) thiab Columbium (Cb) yog lwm lub npe rau tib lub ntsiab lus.
Cov Khoom Siv Tensile

Qhov elongation ntawm no tsuas yog qhov tsawg kawg nkaus xwb.
Lwm Yam Kev Xeem
ASTM A333 muaj kev sim flattening, kev sim cuam tshuam, ntxiv rau kev sim tensile.
Cov hauv qab no yog qhov kub ntawm kev sim cuam tshuam rau qib 6:
