Irahiko Whakarewa Kowiri tira
A402
GB/T E310-16
AWS A5.4 E310-16
Whakaahuatanga: Ko te A402 he hiko kowiri tira austenitic parakore Cr26Ni21 me te paninga konupūmā titanium. Ka taea te whakamahi mō te AC me te DC me te mahi tino pai. He pai te ātete waikura o te konganuku kua whakatakotoria i raro i te pāmahana teitei o te 900 ~ 1100 ℃.
Te Whakamahinga: Whakamahia mō te whakarewa i te momo rino kowiri tira ātete-wera kotahi e mahi ana i raro i ngā āhuatanga pāmahana teitei, ā, ka taea hoki te whakamahi mō te whakarewa i ngā rino chromium whakapakeke (pēnei i te Cr5Mo, Cr9Mo, Cr13 me te Cr28, me ētahi atu) me ngā rino rerekē.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| 0.08 ~ 0.20 | 1.0 ~ 2.5 | ≤0.75 | 25.0 ~ 28.0 | 20.0 ~ 22.5 | ≤0.75 | ≤0.75 | ≤0.030 | ≤0.030 |
Ngā āhuatanga hangarau o te konganuku whakarewa:
| tūemi whakamātautau | Te kaha o te kume Mpa | Te whakaroa % |
| Kua whakamanahia | ≥550 | ≥25 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Pānui:
- Me tunu te hiko mō te 1 hāora i te pāmahana tata ki te 250℃ i mua i te mahi whakarewa;
- Nā te mea he papaku te hohonutanga o te urunga i te wā e whakarewahia ana te hiko AC, me whakamahi te pūtake hiko DC kia hohonu ake te urunga, ā, kaua hoki te iahiko e nui rawa kia kore ai e whero te tokotoko whakarewa.
I whakatūria a Wenzhou Tianyu Electronic Co., Ltd. i te tau 2000. Neke atu i te 20 tau mātou e mahi ana i te hanga i ngā irahiko whakarewa, ngā tokotoko whakarewa, me ngā taputapu whakarewa.
Ko ā mātou hua matua ko ngā irahiko whakarewa kowiri tira, ngā irahiko whakarewa maitai waro, ngā irahiko whakarewa koranu iti, ngā irahiko whakarewa mata, ngā irahiko whakarewa koranu nikara me te kobalta, ngā waea whakarewa maitai ngawari me te koranu iti, ngā waea whakarewa koranu kore waikura, ngā waea whakaheke hau-ārai, ngā waea whakarewa konumohe, ngā waea whakarewa pewa ruku. ngā waea, ngā waea whakarewa koranu nikara me te kobalta, ngā waea whakarewa parahi, ngā waea whakarewa TIG me te MIG, ngā irahiko tungsten, ngā irahiko keri waro, me ētahi atu taputapu whakarewa me ngā taonga pau.
