ASTM A213 alyaj tib asye san pwoblèm yo pwodui swa pa frèt-trase oswa cho woule, jan sa espesifye.Klas TP347HFG dwe fini frèt.Tretman chalè dwe fè separeman ak anplis chofaj pou fòme cho.Alyaj feritik la ak feritik Nerjaveèi yo dwe rechofe.Nan lòt men an, tib asye pur austenitic yo dwe founi nan kondisyon an chalè-trete.Altènativman, imedyatman apre yo fin fòme cho, pandan y ap tanperati a nan tib yo pa mwens pase tanperati a solisyon minimòm, tib yo ka separeman endividyèlman nan dlo oswa rapidman refwadi pa lòt mwayen.
