Kei roto i tenei whakakitenga te maha o nga tohu o te ingoa-taiepa-te matotoru, te ngongo kowiri tira mo te ratonga aukati-waikura me te wera teitei.Ko te nuinga o enei tohu e mohiotia ana ko nga momo "straight-chromium" me te tohu he ferromagnetic.E rua o enei reanga, TP410 me UNS S 41500 (Ripanga 1), ka taea ki te whakapakeke ma te whakamahana wera, a, ko nga koranu chromium teitei, ko nga koranu ferritic he tairongo ki te kakari-brittleness i runga i te whakamahana puhoi ki te mahana noa.Me mohio enei ahuatanga ki te whakamahi i enei rauemi.Ko te karaehe TP439 e whakamahia ana mo te ratonga taika wai wera, kaore e hiahiatia he maimoatanga wera i muri i te wera hei aukati i te whakaekenga o te rohe e pa ana ki te wera.
