Umenzi kunye nemeko
Imibhobho yentsimbi ye-ASTM A213 T12 iya kwenziwa yinkqubo engenamthungo kwaye iya kuba shushu igqitywe okanye igqitywe kubanda, njengoko kuchaziwe.
Unyango lobushushu
Yonke imibhobho yentsimbi ye-T12 iya kunyangwa ngobushushu.
Iindlela zokunyanga ubushushu ezivumelekileyo ziquka full okanye isothermal annealing, normalizing kunye nobushushu, okanyeukuhlaziya okungaphantsi.
| IBanga | Uhlobo lokunyanga ubushushu | I-Subcritical Annealing okanye iqondo lobushushu |
| I-ASTM A213 T12 | i-anneal epheleleyo okanye ye-isothermal | - |
| lungelelanisa kwaye ube nomsindo | - | |
| subcritical aneal | 1200-1350 ℉ [650-730 ℃] |
Kufuneka kuqatshelwe ukuba unyango olushushu kufuneka luqhutywe ngokwahlukileyo kwaye ngaphezu kokubunjwa okushushu.
| IBanga | Ukuqamba, % | ||||||
| C | Mn | P | S | Si | Cr | Mo | |

| Uvavanyo lokucaba | Uvavanyo olunye lokucaba luya kwenziwa kwisampulu nganye ekupheleni komnye umbhobho ogqityiweyo, hayi lowo usetyenziselwa uvavanyo lokuvutha, kwiqashiso ngalinye. | |
| Uvavanyo oluvuthayo | Uvavanyo olunye lokuvutha luya kwenziwa kwisampulu nganye ekupheleni komnye umbhobho ogqityiweyo, hayi lowo usetyenziselwa uvavanyo lokucaba, kwiqashiso ngalinye. | |
Ityhubhu nganye iya kufakwa kuvavanyo lombane olungonakalisiyo okanye uvavanyo lwe-hydrostatic.Uhlobo lovavanyo oluza kusetyenziswa luya kuba kukhetho lomenzi, ngaphandle kokuba kuchazwe ngenye indlela kumyalelo wokuthenga.
Iindlela zokuvavanya ziya kwenziwa ngokuhambelana neemfuno ezisebenzayo zeCandelo 25 kunye ne-26 ye-ASTM A1016.
Ubukhulu betyhubhu ye-ASTM A213 T12 kunye nobukhulu bodonga budla ngokubonelelwa ngeedayamitha zangaphakathi ukusuka kwi-3.2 mm ukuya kwidayamitha yangaphandle ye-127 mm, kunye nobukhulu bodonga obuncinane ukusuka kwi-0.4 mm ukuya kwi-12.7 mm.
Olunye ubungakanani beepayipi zensimbi ze-T12 nazo zingabonelelwa, ngaphandle kokuba zonke ezinye iimfuno ze-ASTM A213 zidibene.
I-ASTM A213 T12 i-alloy yensimbi ye-alloy tubes isetyenziselwa ngokukodwa kwiindawo eziphezulu zokushisa kunye noxinzelelo oluphezulu. Usetyenziso oluqhelekileyo lubandakanya
