Waea kowiri tira

Waea kowiri tira

Ko te kowiri tira he rino teitei te rahi ka taea te aukati i te aukati i te hau, i te kohinga matūriki matū ranei. He pai te parekura o te kowhatu ko te kowiri. Kaore e tika kia atawhaihia e te maimoatanga mata penei i te whakatakotoranga, engari ka kaha te whakaputa i nga ahuatanga o te kowiri tira. He momo maitai te whakamahi i roto i nga waahanga maha ka kiia ko te kowiri tira. Kei roto i te mahinga a te māngai 13 te kowiri tira, 18-8 te kowiri-a-tinana me etahi atu whekau teitei.

Mai i te tirohanga o te whakarewahia, na te mea ko te kowiri tira he chromium, he kiriata chromium tino kikokore ka hangaia i te mata. Ka wehe te kiriata nei i te hāora e whakaeke ana i te maitai me te mahi i te mahi totika.
Kia mau tonu ai te parekura o te kowiri tira, me nui ake te rahi o te kowiri.
304 he kowiri tira-kore e whakamahia nuitia ana ki te hanga taputapu me nga waahanga e hiahia ana ki te mahi tika (ko te kowiri tira he tohu o te kowiri tira. Ko te 304 he rite ki te 0cr19ni9 o taku whenua (0CR18NI9) he kowiri tira. 304 Kei roto i te 19% kromium me te 9% nickel.
Ko te 304 te kowiri tira he kowiri tira me te kowiri-wera. Whakamahia ai i roto i nga taputapu whakaputa kai, nga taputapu matū, te kaha karihi, me etahi atu.
