ASTM A333 Icyiciro cya 6ni carbone ibyuma byifashishwa muri cryogenic nibindi bikorwa bisaba gukomera.Irashoboye gukoreshwa mubidukikije munsi ya -45 ° C (-50 ° F) kandi iraboneka muburyo bwombi kandi budasudutse.
ASTM A333 irashobora gukoreshwa muri ainzira idahwitse cyangwa isudira.
Inzira y'icyuma idafite icyerekezo igabanijwemo ubushyuhe bushyushye kandi bukonje.Kandi bigomba kwigaragaza hejuru yikimenyetso.
Imiyoboro idafite ibyuma nimwe ihitamo ryambere kubidukikije bikaze, ibihe bitesha umutwe, kandi mugihe hakenewe imiyoboro idasanzwe.
ASTM A333 GR.6 igomba kuvurwa ukurikije bumwe muburyo bukurikira bwo kugenzura microstructure:
● Ubusanzwe: Shyushya ubushyuhe bumwe byibura 1500 ° F [815 ° C], hanyuma ukonje mu kirere cyangwa mu cyumba gikonjesha cy'itanura rigenzurwa n'ikirere.
Ubushyuhe nyuma yo gukora ibisanzwe: Nyuma yo kubisanzwe, birashobora gushyuha kubushyuhe bukwiye kubushake bwabashinzwe.
● Kuburyo butagira ikidodo, ibi birashobora kugerwaho mugucunga ubushyuhe bwakazi gashyushye nigikorwa cyo kurangiza gishyushye kuburyo ubushyuhe bwa nyuma buri hagati ya 1550 na 1750 ° F [845 kugeza 945 ° C] hanyuma ugakonja mukirere cyangwa mukirere- itanura rigenzurwa kuva ubushyuhe bwambere byibuze 1550 ° F [845 ° C].
Ubushyuhe nyuma yo kugenzurwa no gukora ubushyuhe no kurangiza ubushyuhe burashobora gushyukwa kubushyuhe bukwiye kubushake bwuwabikoze.
● Kuzimya no gutwarwa: Aho kugira ngo habeho uburyo bwo kuvura hejuru, imiyoboro idafite icyiciro cya 1, 6, na 10 irashobora kuvurwa no gushyushya ubushyuhe bumwe byibura 1500 ° F [815 ° C], hagakurikiraho kuzimya amazi na gushyushya ubushyuhe bukwiye.
AKuri buri kugabanuka kwa 0,01% karubone munsi ya 0,30%, kwiyongera kwa 0,05% manganese hejuru ya 1.06% byakwemererwa kugera kuri 1.35%.
CKubwumvikane hagati yuwabikoze nuwaguze, imipaka ya niobium irashobora kongerwa kugera kuri 0.05% kubisesengura ryubushyuhe na 0.06% kubisesengura ryibicuruzwa.
DAmagambo Niobium (Nb) na Columbium (Cb) ni amazina asimburana kubintu bimwe.
