Ko te SUS347 (347/S34700/0Cr18Ni11Nb) he momo maitai he kowiri tira austenitic, he pai te ātete ki te waikura karaihe.
He pai te ātete ki te waikura i roto i te wai waikawa, te kawakore me te tote, ā, he pai te ātete ki te waikura me te kaha ki te whakarewa i te hau i raro i te 800 °C. He pai rawa atu te mahi a te maitai kore waikura 347 ki te pakaru i te ahotea pāmahana teitei (Stress Rupture) me te ātete ki te ngoki pāmahana teitei, he pai ake ngā āhuatanga miihini o te maitai kore waikura 304. He whānuitia te whakamahinga i roto i te rererangi, te whakaputa hiko, te matū, te hinu matū, te kai, te pepa me ētahi atu mara.
