ASTM A333 Giredi 6ndi chubu chachitsulo cha kaboni chomwe chimagwiritsidwa ntchito popanga zinthu zofewa komanso zina zomwe zimafuna kulimba kolimba. Chimatha kugwiritsidwa ntchito m'malo otsika ngati -45°C (-50°F) ndipo chimapezeka m'njira zosasokonekera komanso zolumikizidwa.
ASTM A333 ingagwiritsidwe ntchito ngatinjira yopanda msoko kapena yolumikizidwa.
Njira yopangira chitoliro chachitsulo chosasunthika imagawidwa m'magulu awiri: kutentha ndi kuzizira. Ndipo iyenera kuwonetsedwa pamwamba pa chizindikirocho.
Machubu achitsulo chosasunthika ndi chisankho choyamba pa malo ovuta, mikhalidwe yovuta, komanso pamene machubu okhuthala kwambiri amafunika.
ASTM A333 GR.6 iyenera kukonzedwa motsatira njira imodzi mwa izi kuti ilamulire kapangidwe kake kakang'ono:
● Kukonza zinthu: Tenthetsani kutentha kofanana kwa osachepera 1500 °F [815 °C], kenako muziziziritse mumlengalenga kapena m'chipinda choziziritsira cha ng'anjo yoyendetsedwa ndi mlengalenga.
● Kutenthetsa pambuyo posintha: Pambuyo posintha, ikhoza kutenthetsedwanso kutentha koyenera malinga ndi zomwe wopanga akufuna.
● Pa njira zosasokoneza, izi zitha kuchitika powongolera kutentha kwa ntchito yotentha ndi ntchito zomaliza kutentha kotero kuti kutentha komaliza kukhale pakati pa 1550 mpaka 1750 °F [845 mpaka 945 °C] kenako kuziziritsa mumlengalenga kapena mu ng'anjo yoyendetsedwa ndi mlengalenga kuchokera kutentha koyambirira kwa osachepera 1550 °F [845 °C].
● Kutenthetsa kutentha pambuyo pogwira ntchito yotentha bwino komanso kumaliza kutentha kumatha kutenthetsedwanso kutentha koyenera malinga ndi zomwe wopanga akufuna.
● Kuzimitsa ndi Kutenthetsa: M'malo mwa njira zilizonse zomwe zili pamwambapa, machubu opanda msoko a Giredi 1, 6, ndi 10 akhoza kutenthedwa mpaka kutentha kofanana kwa 1500 °F [815 °C], kutsatiridwa ndi kuzimitsa m'madzi ndikutenthetsanso mpaka kutentha koyenera.
APa kuchepetsa kulikonse kwa 0.01% ya kaboni pansi pa 0.30%, kuwonjezeka kwa 0.05% ya manganese pamwamba pa 1.06% kungaloledwe kufika pa 1.35% ya manganese.
CMwa mgwirizano pakati pa wopanga ndi wogula, malire a niobium angakwezedwe mpaka 0.05% pakuwunika kutentha ndi 0.06% pakuwunika kwa malonda.
DMawu akuti Niobium (Nb) ndi Columbium (Cb) ndi mayina ena a chinthu chomwecho.
