Whakaahuatanga: Ko te AF2209-15 he hiko kowiri tira takirua kei roto he hauota waro-iti rawa, he iti hoki te paninga hauwai. Whakamahia te DCEP (hiko au tika). He tino pai te mahi. Nā te mea kei roto he molybdenum me te hauota, ā, he tino iti te ihirangi waro, he pai te ātete ki te pakaru me te waikura o te konganuku kua whakatakotoria, inā koa te ātete ki te waikura ahotea.
Te Whakamahinga: Ka whakamahia whānuitia mō te whakarewa i te momo rauemi maitai kore waikura waro-iti rawa i roto i ngā ahumahi hinu me te waipēhi. Pērā i te whakarewa i te maitai kore waikura takirua 022Cr22Ni5Mo3N.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Ni | Mo | N | Cu | S | P |
| ≤0.04 | 0.5 ~ 2.0 | ≤0.90 | 21.5 ~ 23.5 | 8.5 ~ 10.5 | 2.5 ~ 3.5 | 0.08 ~ 0.20 | ≤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 | ≥690 | ≥20 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 50 ~70 | 80 ~ 110 | 130 ~ 150 | 160 ~ 200 |
Pānui:
1. Me tunu te hiko mō te 1 hāora i te pāmahana tata ki te 250℃ i mua i te mahi whakarewa;
2. He mea nui kia horoia te waikura, te unahi hinu, te wai, me ngā poke i runga i ngā wāhanga whakarewa i mua i te whakarewa.
I whakatūria a Wenzhou Tianyu Electronic Co., Ltd. i te tau 2000. Kua uru mātou ki te hanga ohiko whakarewas, 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.
