409 430 439 441 443 pereti kowiri tira
Whakaahuatanga whakaputa:
400 raupapa kowiri tira he koranu rino, waro me te chromium. Na te mea karekau he nickel,
he kowiri tira nickel-save, e mohiotia ana ko te kowiri tira. 400 raupapa kowiri tira he noa
āhuatanga autō na te hanganga martensitic me te rino.
400 raupapa kowiri tira he kaha te ātete ki te waikura teitei o te pāmahana, me tona tinana me te miihini
ka pai ake nga taonga ki te waro maitai. Ko te nuinga o nga raupapa 400 kowiri tira ka taea te wera.

Taupānga:
1. 409 kowiri tira: 409L he kaha te parenga teitei o te pāmahana, ka taea te whakatutuki i te miihini tino pai me te
pūnaha ngongo, me te whakaiti i te matotoru o te pūnaha ngongo, e taea whakaiti tukunga ngengere.
Ko te 409L he iti te utu, he pai te ngawari, he nui te hua me te whakakapi ngawari. He hua hou mo te taiao.
2. 430 kowiri tira: Mo te whakapaipai whare, nga wahi tahu wahie, nga taputapu o te whare, nga waahanga taputapu whare.
Ko te 430F he karaehe rino me nga taonga tapahi kore utu ka taapirihia ki te 430 maitai, e whakamahia ana mo nga miihini aunoa, nga pou me nga nati.
3. 439 he kowiri tira: Elevator, escalator papa whakapaipai; nga panui whakapaipai hoahoanga, penei i nga waahanga hanganga whakapaipai,
paipa hanganga; Nga waahanga o te punaha whakangao miihini; te horoi horoi horoi i roto
4. 441 he kowiri tira: Karekau whakamomori, paipa o mua, KAUPAPA KAUPAPA, me etahi atu o te punaha whakapau waka.
5. 443 he kowiri tira: He kowiri tira 443 he momo kowiri tira ferritic. Ka whakamahia hei whakakapi i te 304.
Ko tana aukati waikura me te mahi tukatuka he ngoikore ake i te 304, engari he iti ake te utu. Kei te whakamahia nuitia i roto i
taputapu hiko, taputapu, taputapu kihini, ararewa, oumu me etahi atu mara.
