I-ASTM A333 iBanga lesi-6sisixhobo se-carbon steel ityhubhu esetyenziswa kwi-cryogenic kunye nezinye izicelo ezifuna ukuqina okunotshi.Iyakwazi ukusetyenziswa kwiindawo eziphantsi njenge -45°C (-50°F) kwaye ifumaneka kuzo zombini iifom ezingenamthungo nezidityanisiweyo.
I-ASTM A333 ingasetyenziswa kwi-ainkqubo engenamthungo okanye edityanisiweyo.
Inkqubo yombhobho yentsimbi engenamthungo yahlulahlulwe yaba kukugqiba okutshisayo kunye nokubanda.Kwaye kufuneka ibonakale ngaphezu kokumakishwa.
Iityhubhu zentsimbi ezingenamthungo lukhetho lokuqala lweendawo ezirhabaxa, iimeko ezinoxinzelelo, kwaye xa kufuneka iityhubhu ezishinyeneyo.
I-ASTM A333 GR.6 kufuneka inyangwe ngenye yezi ndlela zilandelayo ukulawula ubume bayo:
● Ukwenza into eqhelekileyo: Fudumeza ukuya kutsho kubushushu obufanayo obumalunga ne-1500 °F [815 °C], uze uphole emoyeni okanye kwigumbi lokupholisa kwiziko elilawulwa ngumoya ojikeleze umhlaba.
● Ukufudumeza emva kokuqheleka: Emva kokuba kuqhelekile, kunokufudunyezwa kwakhona kwiqondo lokushisa elifanelekileyo ngokubona komenzi.
● Kwiinkqubo ezingenamthungo, oku kunokufezwa ngokulawula amaqondo obushushu omsebenzi oshushu nemisebenzi yokugqiba eshushu ukuze amaqondo obushushu asusela kwi-1550 ukuya kwi-1750 °F [845 ukuya kuma-945 °C] emva koko aphole emoyeni okanye kwiatmosfera- eziko elilawulwayo ukusuka kubushushu bokuqala ubuncinane be-1550 °F [845 °C].
● Ukufudumeza emva kokusebenza okushushu okulawulwayo kunye nokugqiba unyango lobushushu kunokufudunyezwa kubushushu obufanelekileyo ngokubona komenzi.
● Ukucima nokufudumeza: Endaweni yalo naluphi na olu nyango lungasentla, imibhobho engenamthungo yeBanga loku-1, lesi-6 nele-10 inokunyangwa ngokufudumeza iqondo lobushushu elilingana ne-1500 °F [815 °C], lilandelwe kukucinywa kwamanzi kunye ukufudumeza kwakhona kwiqondo lobushushu obufanelekileyo.
AKunciphiso ngalunye lwe-0.01% yekhabhoni engaphantsi kwe-0.30 %, ukunyuka kwe-0.05% yemanganese ngaphezu kwe-1.06 % kuya kuvunyelwa ukuya kubuninzi be-1.35 % manganese.
CNgesivumelwano phakathi komenzi kunye nomthengi, umda we-niobium unokunyuswa ukuya kwi-0.05% kuhlalutyo lobushushu kunye ne-0.06% kuhlalutyo lwemveliso.
DAmagama athi Niobium (Nb) kunye neColumbium (Cb) ngamagama atshintshanayo ale elementi enye.
Ipropati ye-Tensile
| IBanga | Tensile strength | Amandla okunikezela | Ukwandisa | |
| ku-2 phakathi okanye 50 mm, min, % | ||||
| Ixesha elide | Ukunqamleza | |||
| I-ASTM A333 iBanga lesi-6 | 415 MPa [60,000 psi] | 240 MPa [35,000 psi] | 30 | 16.5 |
Ubude obulapha bubuncinane obusisiseko.
Olunye Uvavanyo
I-ASTM A333 inovavanyo oluthe tyaba, uvavanyo lwempembelelo, ukongeza kuvavanyo lwe-tensile.
Oku kulandelayo ngamaqondo obushushu ovavanyo lwebanga lesi-6:
| IBanga | Ubushushu beMpembelelo | |
| ℉ | ℃ | |
| I-ASTM A333 iBanga lesi-6 | - 50 | - 45 |
Umbhobho ngamnye uya kuvavanywa ngombane ongonakaliyo okanye owenziwe ngoxinzelelo olukhulu olwenziwa ngamanzi.
