Irahiko Whakarewa Nikara me te Nikara
Ni327
GB/T ENi6094
AWS A5.11 ENiCrFe-9
Whakaahuatanga: He irahiko nikara te Ni327 me te paninga konutai hauwai-iti. Whakamahia te DCEP (irahiko iahiko tika)(pai). He pai te ātete o te konganuku kua whakatakotoria ki roto i te whakarewa nā te mea he nui ngā huānga whakarewa pērā i te molybdenum me te niobium kei roto i te whakarewa.
Te Whakamahinga: E whakamahia ana mō te whakarewa i ngā koranu nikara e hiahia ana kia ātete ki te wera me te waikura, ā, ka taea hoki te whakamahi mō te whakarewa me te paparanga o ētahi koranu uaua ki te whakarewa me ngā maitai rerekē.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Fe | Si | Cu | Ni | Cr |
| ≤0.15 | 1.0 ~ 4.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥55.0 | 12.0 ~ 17.0 |
| Nb + Ta | Mo | W | S | P | Ētahi atu |

| 0.5 ~ 3.0 | 2.5 ~ 5.5 | ≤1.5 | ≤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 | ≥650 | ≥360 | ≥18 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 3.2 | 4.0 |
| Iahiko whakarewa （A） | 90 ~ 110 | 110 ~ 150 |
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 hinu, te wai, me ngā poke i runga i ngā wāhanga whakarewa i mua i te whakarewa.
