Irahiko Whakarewa Nikara me te Nikara
Ni307-1
GB/T ENi6062
AWS A5.11 ENiCrFe-1
Whakaahuatanga: He irahiko nikara te Ni307-1, he iti te paninga hauwai konutai. Whakamahia te DCEP (irahiko au tika). Nā te mea kei roto i te whakarewa he Nb, he pai te kirihou me te ātete ki te pakaru o te konganuku kua whakatakotoria.
Te Whakamahinga: Whakamahia mō te whakarewa i ngā koranu nikara-kōromium-rino (pēnei i te UNS N06600, UNS N06601) me te whakakikorua i te maitai. He pai ngā āhuatanga whakarewa rerekē. Ka taea hoki te whakamahi i te pāmahana mahi o te 980°C, engari ki te teitei ake te pāmahana i te 820°C, ka heke te ātete me te kaha o te waikura.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Fe | Si | Cu | Ni | Cr | Nb + Ta | S | P | Ētahi atu |
| ≤0.08 | ≤3.5 | ≤11.0 | ≤0.8 | ≤0.5 | ≥62.0 | 13.0 ~ 17.0 | 0.5 ~ 4.0 | ≤0.015 | ≤0.020 | ≤0.50 |
Ngā āhuatanga hangarau o te konganuku whakarewa:
| tūemi whakamātautau | Te kaha o te kume Mpa | Te kaha o te hua Mpa | Te whakaroa % |
| Kua whakamanahia | ≥550 | ≥360 | ≥27 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko whakarewa （A） | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 | 130 ~ 180 |
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 ngā waikura, te hinu, te wai, me ngā poke i runga i ngā wāhanga whakarewa i mua i te whakarewa. Whakamātauria te whakamahi i tētahi pewa poto hei whakarewa.
