ASTM A333 Gawo 6ndi carbon steel chubing material yomwe imagwiritsidwa ntchito mu cryogenic ndi ntchito zina zomwe zimafuna kulimba kwachitsulo.Itha kugwiritsidwa ntchito m'malo otsika mpaka -45 ° C (-50 ° F) ndipo imapezeka mumitundu yonse yopanda msoko komanso yowotcherera.
ASTM A333 itha kugwiritsidwa ntchito mu amsoko kapena welded ndondomeko.
Njira yopanda chitoliro yachitsulo imagawidwa kukhala yotentha komanso yokoka kuzizira.Ndipo iyenera kuwonetsedwa pamwamba pa cholembera.
Machubu achitsulo osasunthika ndiye njira yoyamba yopangira madera ovuta, zovuta, komanso pakafunika machubu okhuthala kwambiri.
ASTM A333 GR.6 ikuyenera kuthandizidwa motsatira imodzi mwa njira zotsatirazi kuti muwongolere mawonekedwe ake:
● Kuchita zinthu mwakamodzikamodzi: Muzitenthetsa mpaka kutentha kufika 1500 ° F [815 °C], kenako muzizizira mumpweya kapena m'chipinda chozizirirapo cha ng'anjo yoyendetsedwa ndi mpweya.
● Kutenthetsa pambuyo pokhazikika: Pambuyo pokhazikika, ikhoza kutenthedwanso ku kutentha koyenera pakufuna kwa wopanga.
● Pochita zinthu mopanda msoko, izi zingatheke mwa kuwongolera kutentha kwa ntchito yotentha ndi ntchito yomaliza yotentha kotero kuti kutentha komaliza kukhale kuyambira 1550 mpaka 1750 °F [845 mpaka 945 °C] ndiyeno kuzizirira mumpweya kapena mumlengalenga- ng'anjo yoyendetsedwa kuchokera pakutentha koyambirira kwa osachepera 1550 °F [845 °C].
● Kutenthetsa pambuyo pogwira ntchito yotentha ndi kutsiriza kutentha kwa kutentha kumatha kutenthedwanso ku kutentha koyenera pakufuna kwa wopanga.
● Kuzimitsa ndi kutenthetsa: M’malo mwa mankhwala alionse amene ali pamwambawa, machubu opanda msoko a Sitandade 1, 6, ndi 10 akhoza kuthiridwa mwa kutenthetsa kutentha kofananako kwa pafupifupi 1500 °F [815 °C], kenaka kuzimitsidwa m’madzi ndi kutenthetsanso kutentha koyenera.
APakuchepetsa kulikonse kwa carbon 0.01% pansi pa 0.30%, kuwonjezeka kwa 0.05% manganese pamwamba pa 1.06% kudzaloledwa kufika pa 1.35 % manganese.
CMwa mgwirizano pakati pa wopanga ndi wogula, malire a niobium atha kuonjezedwa mpaka 0.05% pakuwunika kutentha ndi 0.06% pakuwunika kwazinthu.
DMawu akuti Niobium (Nb) ndi Columbium (Cb) ndi mayina ena a chinthu chomwecho.
