Te ahurei
Ko te hanganga moroiti weld he austenitic ferrite biphase hanganga, kei roto i te 40% ferrite.
Ko te konganuku whakakotahi he tino matawhānui o te austenitic me te ferritic kowiri tira, me te pai te rua me te ahotea te waikura.
He ngohengohe me te pumau te pewa, he iti te pakaru, he ataahua te hanga, he pai te tango para, te whangai waea pumau, me te pai o te mahi whakaahuru.
