Irahiko Whakarewa Nikara me te Nikara
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Whakaahuatanga: He irahiko nikara te Ni307-2, he paninga konutai hauwai-iti. Whakamahia te DCEP (irahiko au tika). Nā te mea kei roto i te whakarewa he nui o te molybdenum, te niobium me ētahi atu huānga whakarewa, he pai te ātete ki te pakaru.
Taupānga: Whakamahia mō te whakarewa i ngā koranu nikara-konukōmiuma-rino (pērā i te UNS N08800, UNS N06600), he tino pai mō te whakarewa i ngā konganuku rerekē, te whakarewa paparanga whakawhiti me te whakarewa mata, ā, ka taea hoki te whakamahi ina 980 °C te pāmahana mahi, engari ka taea te ātete i te waikura ina teitei ake te pāmahana i te 820 °C. He iti te ira me te kaha.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Ētahi atu |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤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 ~ 100 | 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.
