Kakaretso ea Pipe ea Tšepe e sa Khaotseng ea 321
Jwalo ka mofuta o fetotsweng wa SS304, tshepe e sa ruseng 321 (SS321) ke tshepe e sa ruseng ya austenitic e tsitsitseng e nang le titanium e ekeditsweng bonyane ka makgetlo a 5 ho feta carbon. Ho eketswa ha titanium ho fokotsa kapa ho thibela ho utlwa ha pula ya carbide nakong ya ho tjheseletsa le ditshebeletsong mochesong wa 425-815°C. E boetse e ntlafatsa tse ding tsa thepa mochesong o phahameng. SS321 e fana ka kganyetso e ikgethang kgahlanong le oxidation le kutu mme e na le matla a matle a ho kgefutsa. E sebediswa haholoholo disebedisweng tsa ho hlwekisa oli, diphaephe tsa dijana tsa kgatello, di-super heater tse phatsimang, di-bellews le disebedisweng tsa kalafo ya mocheso o phahameng.
