Rau maitai kore waikura AISI 304L
Ngā Taonga Whānui
Kei tā mātou kamupene he pepa kowiri tira 304L, he koranu kowiri tira austenitic raupapa T-300, he iti rawa te 18% chromium me te 8% nickel. Ko te momo 304L he 0.030 te waro mōrahi. Koinei te "kowiri tira 18/8" paerewa e kitea ana i roto i ngā paraharaha me ngā taputapu tunu kai. Ko te koranu 304L te koranu tino maha ngā whakamahinga me te whānui o te whakamahinga i roto i te whānau koranu. He pai mō te whānuitanga o ngā tono kāinga me ngā tono arumoni, he tino ātete te Koranu 304L ki te waikura, ā, he tino ngāwari ki te hanga, he tino pai te āhua. E kiia ana hoki ko ngā koranu kowiri tira austenitic te mea tino ngāwari ki te whakarewa o ngā koranu teitei, ā, ka taea te whakarewa mā ngā tukanga whakarewa honohono me te ātete katoa.

Ngā Paerewa:
ASTM/ASME: S30403
EURONORM: 1.4303
AFNOR: Z2 CN 18.10
DIN: X2 CrNi 19 11
Ātete ki te Waikura:
Ko te ātete ki te waikura i roto i ngā taiao waikura te hua o te 18 ki te 19% chromium kei roto i ngā koranu 304.
Ko te ātete ki ngā waikawa waro kaha te hua o te 9 ki te 11% nikara kei roto i ngā koranu 304.
I ētahi wā, ka iti ake te tere waikura o te koranu 304L i te koranu waro 304 teitei ake; ki te kore, ka kiia pea he ōrite te mahi a te 304, 304L, me te 304H i roto i te nuinga o ngā taiao waikura.
Ko te koranu 304L te mea pai mō te whakamahi i roto i ngā taiao he nui te waikura hei whakapūmau i te waikura intergranular o ngā whakarewa me ngā rohe e pāngia ana e te wera i runga i ngā koranu ngāwari.
Ātete Wera:
He ātete pai ki te waikura i roto i te ratonga wā-poto ki te 1600°F me te ratonga tonu ki te 1690°F.
Kāore i te tūtohutia te whakamahi tonu i te 304 i te awhe 800-1580°F mēnā he mea nui te ātete ki te waikura wai i muri mai.
He ātete ake te karaehe 304L ki te maturuturunga warowaiha, ā, ka taea te whakamahana ki roto i te awhe pāmahana i runga ake nei.
Ngā Āhuatanga o te 304 Alloy
Ngā Āhuatanga o te Whakarewa:
He tino pai ngā āhuatanga whakarewa; kāore e hiahiatia te whakamahana i muri i te whakarewatanga ina whakarewahia ngā wāhanga angiangi. E rua ngā whakaaro nui hei whakaaro i te hanga hononga whakarewa i roto i te austeniticngā maitai kore waikurako:
te tiaki i te ātete ki te waikura
te karo i te pakaru
Te Tukatuka – Te Hanga Wera:
Hei hanga, whakamahanahia kia ōrite ki te 2100 / 2300 °F
Kaua e whakarewa i raro i te 1700 °F
Ka taea te whakamatao i te hanga i te hau me te kore e pakaru
Te Tukatuka – Te Hanga Matao:
Nā tōna hanganga austenitic ka taea te kukume hōhonu me te kore e whakamahanahia, ka waiho koinei te kounga kowiri tira pai rawa atu mō te hanga totohu, oko tuwhera me ngā kohua.
Ka tere te whakapakeketanga o ēnei kōeke. Hei whakamama i ngā ahotea e puta mai ana i te hanganga nui, i te hurihuri rānei, me whakamahana katoa ngā wāhanga, me whakamahana rānei i te whakamama i te ahotea i muri tonu i te hanganga.
Te āheinga mīhini:
E taunakihia ana te whakamahi i ngā mea pakaru maramara nā te mea he uaua pea ngā maramara. Me tere te whakapakeke o te maitai kore waikura, me whakamahi i ngā whāngai taumaha, ngā taputapu koi, me te whakatū pakari. Me tapahi i raro i te paparanga whakapakeke-mahi i puta mai i ngā whitinga o mua.
