Ngā Āhuatanga Matū

Ko te pereti maitai kore waikura 304 he maitai kore waikura austenitic, ko te nuinga he 18% te chromium (Cr) me te 8% te nickel (Ni), ā, he tino pai te ātete ki te waikura, te ngāwari ki te hanga, me te ngāwari ki te whakarewa. Ko tōna hanganga matū noa ko:

Huānga Te hanganga (%)

Konukōmiuma (Kr) 18.0 – 20.0

Nikara (Ni) 8.0 – 10.5

Waro (C) ≤0.08

Manganēhi (Mn) ≤2.0

Hiraka (Si) ≤1.0

Whēkau (P) ≤0.045

Whānariki (S) ≤0.03

Rino (Fe) Taurite

Ngā tono

Nā tōna pakari me tōna ātete ki te waikura, e whakamahia whānuitia ana te pereti maitai kore waikura 304 i roto i:

 Ahumahi Kai me te Inu (tāke tukatuka, whitiki kawe)

 Ngā Taputapu Matū me te Rongoā (ngā tāke rokiroki, ngā tauhohenga)

 Hoahoanga me te Hanganga (ngā panera ararewa, te whakakikorua)

 Ngā Taputapu Hauora me te Taiwhanga (ngā paepae whakahoromata, ngā taputapu pokanga)

 Aunoa me te Rererangi (ngā wāhanga hanganga, ngā pūnaha whakaputa hau)

 Ngā taputapu o te whare me te kīhini (ngā papa kaute, ngā totohu)

 Ngā Whakatakotoranga

Kei te wātea ngā pereti maitai kore waikura 304 i roto i ngā rahi, ngā matotoru, me ngā whakaotinga mata rerekē:

 Awhe Matotoru: 0.1mm ki te 100mm (matotoru ahumahi noa: 0.5mm – 50mm)

 Whānui: 1000mm, 1219mm, 1500mm (paerewa), rahi ritenga rānei

 Roa: 2000mm, 2438mm, 3000mm, ngā roa ritenga rānei

 Ngā Whakaotinga Mata:

 2B: Maeneene, he āta whakaata (he mea tino noa)

 BA (Whakamahana Kanapa): Tino whakaata, rite ki te whakaata

 Nama 4 (Paraihe): He mutunga matte me ngā rārangi kōhatu e kitea ana

 Nama 8 (Whakaata): Kua orohia kia kanapa rawa

 Ngā Paerewa Noa:

ASTM A240 (Whakatakotoranga paerewa mō te pereti maitai kore waikura chromium me te chromium-nickel)

 EN 1.4301 (he rite ki te 304 o Ūropi)

 JIS SUS304 (paerewa Hapanihi)

 GB/T 3280 (paerewa Hainamana)

 He mea rongonui te pereti maitai kore waikura 304 nā te mea he iti te utu, he ātete ki te waikura, he maha hoki ngā whakamahinga i roto i ngā ahumahi me ngā mahi arumoni.
