I-A269 ihlanganisa kokubili i-stainless ehlanganisiwe nengenamthungo yezinhlelo zokusebenza ezijwayelekile noma ezidinga ukumelana nokugqwala kanye nokusetshenziswa kwezinga lokushisa eliphansi noma eliphezulu okuhlanganisa i-304L, 316L kanye ne-321. I-A249 ihlanganiswa kuphela futhi isetshenziselwa izinhlelo zokusebenza zezinga lokushisa eliphezulu (ibhoyila, i-heat exchanger).
