Te Whakarewa Kowiri tiraIrahiko
A067
GB/T E309L-15
AWS E309L-15
Whakaahuatanga: Ko te A067 he momo hiko kowiri tira Cr23Ni13 he iti-hauwai te hauwai. He hiko DCEP (hiko au tika) te whakamahi, ā, ka taea te whakarewa i ngā tūranga katoa. He iti te ihirangi waro, nō reira ka taea te ātete ki te waikura intergranular i puta mai i te maturuturunga carbide me te kore he whakau pēnei i te niobium me te titanium.
Te Whakamahinga: E whakamahia ana mō te momo hanganga maitai kore waikura kotahi, te maitai hiato me ngā wāhanga maitai āhua motuhake i roto i te hanga muka hangai, te hinu matū me ētahi atu taputapu. Ka taea hoki te whakamahi mō te paparanga o ngā paparanga whakawhiti i runga i te pakitara o roto o ngā oko pēhanga tauhohenga karihi me te whakarewa o ngā wāhanga o roto o te pourewa.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.04 | 0.5 ~ 2.5 | ≤0.90 | 22.0 ~ 25.0 | 12.0 ~ 14.0 | ≤0.75 | ≤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 | ≥520 | ≥25 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 50 ~ 70 | 80 ~ 120 | 130 ~ 160 | 160 ~ 200 |
Pānui:
1. Me tunu te hiko mō te 1 hāora i te pāmahana tata ki te 300℃ 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.
