304 he kowiri tira tetahi momo whanui, no te austenitiko he kowiri tira. Kei te whakamahia whānuitia i roto i te umanga whakarewa. Ko te kohinga 304 kowiri tira ko te 18% chromium me te 8% nikara. He kore-aukume. Mena he nui nga waahanga poke, ka kitea i etahi wa te ngoikore ngoikore i muri i te tukatuka. Ko tenei aukume ngoikore ka taea noa te whakakore i te maimoatanga wera. Na te mea he kowiri tira kaore e taea te whakarereke te hanganga whakarewa i te maimoatanga wera.
I te paerewa o te ao, ko nga tohu e rite ana ki te 304 te kowiri tira: 1.4301, X5CrNi18-10, S30400, CF8 me 06Cr19Ni10. Ko tetahi o nga taonga e whakamahia whaaia ana e te kowiri tira, ko te 304 kowiri tira he mea nui ki te mahi ki o taatau kaihoko.
▶ Nga Mahinga o te Whakangaanga Whakangao i te RMC Hanga Kete
• Te Rahi Nui: 1,000 mm × 800 mm × 500 mm
• Awhe Taumaha: 0.5 kg - 100 kg
• Raukaha ā-Tau: 2000 tana
• Nga Rauemi Paihere mo te Hanga Shell: Silica Sol, Water Glass me a raatau ranunga.
• Tolerances: I Tono.
▶ Huarere Whakangaanga Putanga
• Tauira & Hoahoa Utauta → Hanga Mate Mate → Weronga Whiatini → Huihuinga Miihini → Hanga Miihini → Waihorihuri → Tauhokohoko Tauhokohoko Miihini → Te reinga me te ringihia → Te horoi, te huri me te pupuhi pere → Tukatukahia ana te Tukatuka me te Paapaki hei Tukunga
▶ Me Pehea Te Tirotiro i nga Tiwhikete Tino Kowiri
Te wetewete me te taatai a-ringa i te taatai
• Te wetewete Metallographic
• Ko te tirotiro pakeke o Brinell, Rockwell me Vickers
• Te wetewete i nga rawa miihini
• He iti me te ngawari te whakamatautau i te paanga o te paemahana
• Te tirohanga ma
• Tirohanga UT, MT me RT
▶ Tukanga Whakairi
• Te Whakaheke me te Horoi
• Te Ngingio Kiriata / Peening Peera
• Maimoatanga Wera: Maamaa, Whakamaa, Whakamaaonga, Maamaa, Nitriding
• Maimoatanga Mata: Passivation, Anodizing, Electroplating, Hot Zinc Plating, Zinc Plating, Nickel Plating, Polishing, Electro-Polishing, Peita, GeoMet, Zintec.
• Miihini: Te Hurihanga, Te Miihini, Te Ngawha, te Tarai, Te Hononga, te huri.
▶ Painga o te Tino Kowhiowhiowhiitanga Whakangaanga:
• He pai te oti me te maeneene o te papa
• Te manawanui ki nga taarua.
• Nga ahuatanga matatini me te uaua hoki me te ngawari o te hoahoa
• Te kaha ki te maka i nga pakitara angiangi na reira he mea maama noa te waahanga
• He whanui te kowhiri me te koranu (he kiki me te kore-koro)
• Kaore e hiahiatia te tauira ki te hoahoa pokepokea ai.
• Whakaitihia te hiahia mo nga miihini tuarua.
• Nga ururua rauemi iti.
