ASTM A213 T9, e tsejoang hape e le ASME SA213 T9, ke motsoako o tlasetube ea tšepe e se nang sekolie sebelisetsoa liboiler, li-superheater le li-heat exchanger.
T9 ke motsoako oa chromium-molybdenum o nang le 8.00–10.00% ea chromium le 0.90–1.10% ea molybdenum. E na le matla a ho thaepa a bonyane 415 MPa le matla a ho hlahisa a bonyane 205 MPa. Ka matla a eona a matle a mocheso o phahameng, khanyetso ea oxidation, le khanyetso ea ho thekesela, T9 e sebetsa ka mokhoa o tšepahalang tlas'a maemo a ts'ebetso a mocheso o phahameng le khatello e phahameng.
