Whakaahuatanga: He hiko kowiri tira Cr23Ni13Mo2 te A312, he paninga konupūmā titanium tōna. Ka taea te whakamahi mō te AC me te DC, ā, he tino pai te mahi. He pai ake tōna ātete ki te waikura, te pakaru, me te waikura i te A302 nā te mea kei roto i te konganuku kua whakatakotoria he molybdenum.
Te Whakamahinga: E whakamahia ana mō te whakarewa i te momo ipu kowiri tira kotahi e ātete ana ki te waikura mā te waikawa whanariki (amonia sulfide), ā, ka taea hoki te whakamahi mō te whakarewa i te arai kowiri tira, te pereti maitai kua whakakikoruatia me te maitai rerekē.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.12 | 0.5 ~ 2.5 | ≤0.90 | 22.0 ~ 25.0 | 12.0 ~ 14.0 | 2.0 ~ 3.0 | ≤0.75 | ≤0.030 | ≤0.040 |
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 150℃ 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. Kua uru mātou ki te hanga i ngā irahiko whakarewa,ngā tokotoko whakarewa, mengā mea whakapau mō te whakarewamō ngā tau neke atu i te 20.
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.
