He kowiri tira hiko E320-16 nga mea tito weld
Taupānga
He pai mo te maha o nga ahuatanga e hiahiatia ana te waikawa pungatara, te sulfite me o ratou tai ki te aukati i te pirau kino. I te nuinga o te waa ka whakamahia mo te whakapiri i nga rawa turanga me nga momo tito rite, penei i te Alloy20 me UNS N08020, me etahi atu. Kei te whakamahia nuitia i roto i te hanga taputapu matū me te hauwai.
