I-ASTM A333 Ibanga 6iwumshini wokufaka ipayipi wensimbi yekhabhoni osetshenziswa ekusetshenzisweni kwe-cryogenic nakwezinye izinhlelo zokusebenza ezidinga ukuqina okunezimbobo. Ingasetshenziswa ezindaweni eziphansi njenge--45°C (-50°F) futhi itholakala kokubili ngezindlela ezingenamthungo nezihlanganisiwe.
I-ASTM A333 ingasetshenziswa ku-inqubo engenamthungo noma ehlanganisiwe.
Inqubo yepayipi lensimbi engenamthungo ihlukaniswe ngokushisa okuphelile kanye nokubanda okudonswe phansi. Futhi idinga ukuboniswa ngaphezu kophawu.
Amashubhu ensimbi angenamthungo ayisinqumo sokuqala ezindaweni ezinzima, izimo ezicindezelayo, kanye nalapho kudingeka amashubhu aqinile kakhulu.
I-ASTM A333 GR.6 idinga ukuphathwa ngokwenye yezindlela ezilandelayo zokulawula isakhiwo sayo esincane:
● Ukulungisa: Shisa kufike ezingeni lokushisa elifanayo okungenani elingu-1500 °F [815 °C], bese uphola emoyeni noma ekamelweni lokupholisa lesithando esilawulwa umoya.
● Ukushisa ngemva kokushisa: Ngemva kokushisa, kungase kufudunyezwe kuze kufike ezingeni lokushisa elifanele ngokubona komkhiqizi.
● Ngezinqubo ezingenamthungo, lokhu kungafezwa ngokulawula amazinga okushisa omsebenzi oshisayo kanye nemisebenzi yokuqeda ukushisa ukuze amazinga okushisa okugcina asuke ku-1550 kuya ku-1750 °F [845 kuya ku-945 °C] bese ephola emoyeni noma esithandweni esilawulwa umoya kusukela ekushiseni kokuqala okungenani okungu-1550 °F [845 °C].
● Ukushisa ngemva kokusebenza okushisa okulawulwayo kanye nokwelashwa kokushisa kokuqeda kungashiswa kabusha kuze kufike ezingeni lokushisa elifanele ngokubona komenzi.
● Ukucima nokushisa: Esikhundleni sanoma yikuphi ukwelashwa okungenhla, amashubhu angenamthungo eBanga 1, 6, kanye ne-10 angase aphathwe ngokushisa okulinganayo okungenani okungu-1500 °F [815 °C], kulandelwe ukucima emanzini bese kufudumala kabusha kufike ezingeni lokushisa elifanele lokushisa.
ANgokunciphisa ngakunye kwe-carbon engu-0.01% ngaphansi kuka-0.30%, ukwanda kwe-manganese engu-0.05% ngaphezu kuka-1.06% kuzovunyelwa kufike ku-1.35% manganese.
CNgokuvumelana phakathi komkhiqizi nomthengi, umkhawulo we-niobium ungakhushulwa ufike ku-0.05% ekuhlaziyweni kokushisa kanye no-0.06% ekuhlaziyweni komkhiqizo.
DAmagama athi Niobium (Nb) kanye neColumbium (Cb) angamagama ahlukile ento efanayo.

Ukwandiswa lapha kumane nje kuyisilinganiso esiyisisekelo.
Ezinye Izivivinyo
I-ASTM A333 inokuhlolwa kokuthamba, ukuhlolwa komthelela, ngaphezu kokuhlolwa kokudonsa.
Okulandelayo amazinga okushisa okuhlolwa komthelela webanga lesi-6:
| Ibanga | Izinga Lokushisa Elithinta Umthelela | |
| ℉ | ℃ | |
| I-ASTM A333 Ibanga 6 | - 50 | - 45 |
Ipayipi ngalinye kufanele lihlolwe ngogesi noma nge-hydraulic ngendlela engonakalisi.
Ukuhlolwa kwe-hydrostatic:I-ASTM A999Isigaba 21.2 sizolandelwa;
Ukuhlolwa kukagesi okungonakalisi: kufanele kuhambisane nezidingo ze-ASTM A999, iSigaba 21.3;
Okujwayelekile: ASTM A333;
Ibanga: Ibanga lesi-6 noma i-GR 6
Uhlobo Lwepayipi: Ipayipi lensimbi elingenamthungo noma elihlanganisiwe;
