Ripple pai
He iti te hauwai kowiri tira hiko hiko, ko te waahanga matua he iti te C-22%Cr-12%Ni, he iti te ihirangi waro me te aukati pai.
He pai te mahi fehokotaki'anga, arc u, ataahua hanga,
ripple ngawari, paku paku, ngawari te tango para;
Ko te paninga he pai te ahi, he pai te porosity,
pūmau āhuatanga pūkaha o te whakarewa whakarewa, me te tere X-Ray tuku.
