Rino Pāmahana ItiWhakarewaIrahiko
W707Ni
GB/T E5515-C1
Whakaahuatanga: Ko te W707Ni he hiko maitai pāmahana-iti kei roto ko te Ni i roto i te paninga konutai hauwai-iti. Ka whakamahia te DCEP (hiko hiko au tika) ā, ka taea te whakarewa i ngā tūranga katoa. He pai tonu te pakari o te konganuku kua whakatakotoria ki te -70°C.
Whakamahinga: Whakamahia mō te whakarewa i te maitai pāmahana iti pēnei i te 2.5Ni.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Ngā āhuatanga hangarau o te konganuku whakarewa:
| tūemi whakamātautau | Te kaha o te kume Mpa | Te kaha o te hua Mpa | Te whakaroa % | Uara pānga (J) -70℃ |
| Kua whakamanahia | ≥540 | ≥440 | ≥17 | ≥27 |
Te nui o te hauwai horapa o te konganuku kua whakatakotoria: ≤6.0mL/100g (tikanga glycerin) ≤10mL/100g rānei (tikanga mercury, tikanga chromatography hau rānei)
Tirotiro hihi-X: tohu I
Iahiko e taunakitia ana:
| （mm） Te whānui o te tokotoko | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| （A） Iahiko Whakarewa | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Pānui:
- Me tunu te hiko mō te 1 hāora i te 350℃ i mua i te mahi whakarewa;
- 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;
- Ngāna kia iti te kaha o ngā aho ina whakarewahia ana, he whakarewa maha-paparanga me te whakarewa maha-haerenga.
