I-ASTM A333 Ibanga lesi-6sisixhobo setyhubhu yentsimbi yekhabhoni esisetyenziswa kwi-cryogenic nakwezinye izinto ezifuna ukuqina okuncinci. Singasetyenziswa kwiindawo ezingaphantsi kwe--45°C (-50°F) kwaye sifumaneka ngeendlela ezingenamthungo kunye ne-welded.
I-ASTM A333 ingasetyenziswa kwi-inkqubo engenamthungo okanye edibeneyo.
Inkqubo yombhobho wentsimbi engenamthungo yahlulwe yaba yi-hot finish kunye ne-cold draw. Kwaye kufuneka iboniswe ngaphezulu kwephawu.
Iityhubhu zentsimbi ezingenamthungo zezona zikhethwa kuqala kwiindawo ezinzima, kwiimeko ezixinzelelekileyo, kwaye xa kufuneka iityhubhu ezixineneyo kakhulu.
I-ASTM A333 GR.6 kufuneka iphathwe ngokwenye yeendlela ezilandelayo zokulawula isakhiwo sayo esincinci:
● Ukulungisa: Fudumeza ubushushu obufanayo ubuncinane obuyi-1500 °F [815 °C], uze upholise emoyeni okanye kwigumbi lokupholisa lesithando esilawulwa ngumoya.
● Ukufudumala emva kokulungiswa: Emva kokulungiswa, ingafudunyezwa kwakhona ukuya kubushushu obufanelekileyo bokufudumala ngokokubona komenzi.
● Kwiinkqubo ezingenamthungo, oku kungenziwa ngokulawula amaqondo obushushu omsebenzi oshushu kunye nemisebenzi yokugqiba ubushushu ukuze amaqondo obushushu okugqibela abe phakathi kwe-1550 ukuya kwi-1750 °F [845 ukuya kwi-945 °C] aze aphole emoyeni okanye kwisithando somoya esilawulwa ngumoya ukusuka kubushushu bokuqala obuyi-1550 °F [845 °C].
● Ukufudumala emva kokusebenza ngobushushu obulawulwayo kunye nokugqiba unyango lobushushu kunokuphinda kufudunyezwe ukuya kubushushu obufanelekileyo ngokokubona komenzi.
● Ukucima nokulungisa: Endaweni yonyango olungentla, iityhubhu ezingenamthungo zeBanga loku-1, lesi-6, nelesi-10 zinokulungiswa ngokufudumeza ukuya kubushushu obufanayo obuyi-1500 °F [815 °C], kulandele ukucima emanzini kunye nokufudumala kwakhona ukuya kubushushu obufanelekileyo bokulungisa.
AKwixabiso ngalinye lokunciphisa i-0.01% yekhabhoni ngaphantsi kwe-0.30%, ukunyuka kwe-0.05% yemanganese ngaphezu kwe-1.06% kuya kuvunyelwa ukuya kuthi ga kwi-1.35% yemanganese.
CNgokwesivumelwano phakathi komenzi kunye nomthengi, umda we-niobium unokwandiswa ukuya kuthi ga kwi-0.05% kuhlalutyo lobushushu kunye ne-0.06% kuhlalutyo lwemveliso.
DAmagama athi Niobium (Nb) kunye neColumbium (Cb) ngamagama ahlukeneyo ento enye.
Ipropati yokuThatha
| Ibanga | Tensile strength | Amandla okuvumela | Ukwandiswa | |
| kwi-2 in. okanye i-50 mm, min, % | ||||
| I-Longitudinal | I-Transverse | |||
| I-ASTM A333 Ibanga lesi-6 | I-415 MPa [60,000 psi] | 240 MPa [35,000 psi] | 30 | 16.5 |
Ukwandiswa apha yeyona nto iphambili.
Ezinye Iimvavanyo
I-ASTM A333 inovavanyo lokuthamba, uvavanyo lokuchaphazeleka, ukongeza kuvavanyo lokutsalwa.
Oku kulandelayo ngamaqondo obushushu ovavanyo lwempembelelo kwibanga lesi-6:
| Ibanga | Ubushushu obunempembelelo | |
| ℉ | ℃ | |
| I-ASTM A333 Ibanga lesi-6 | - 50 | - 45 |
Umbhobho ngamnye kufuneka uvavanywe ngombane okanye nge-hydraulic ukuze ungatshabalalisi.
