Irahiko Whakarewa Rino Koranu Iti
J707RH
GB/T E7015-G
AWS E10015-G
Whakaahuatanga: He hiko hauwai tino iti te kaha o te J707RH, he paninga hauwai konutai iti. He DCEP (hiko iahiko au tika) te whakamahinga, ā, ka taea te whakarewa i ngā tūranga katoa. He pai te mahi whakarewa. He pai te piko makariri, te ātete ki te pakaru me te ātete ki te pahūtanga o ngā hononga whakarewa. He tino ngāwari, he pakari hoki te konganuku kua whakatakotoria.
Te Whakamahinga: E whakamahia ana mō te whakarewa i ngā hanganga anga, ā, he pai hoki mō te whakarewa i ngā hanganga nui o te maitai kaha-teitei Rp0.2≥590MPa.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Cr | Si | Ni | Mo | S | P | S + P |
| ≤0.10 | 1.20 ~ 1.60 | 0.08 ~ 0.20 | 0.30 ~ 0.60 | 1.40 ~ 2.00 | 0.25 ~ 0.50 | ≤0.020 | ≤0.020 | ≤0.035 |
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) -50℃ |
| Kua whakamanahia | ≥690 | ≥590 | ≥15 | ≥34 |
Te nui o te hauwai horapa o te konganuku kua whakatakotoria: ≤4.1mL/100g (tikanga chromatography mercury, hau rānei)
Tirotiro hihi-X: tohu I
Iahiko e taunakitia ana:
| （mm） Te whānui o te tokotoko | 4.0 | 5.0 |
| （A） Iahiko Whakarewa | 160 ~ 180 | 180 ~ 220 |
Pānui:
1. Me tunu te hiko mō te 2 hāora i te 400℃ 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;
3. Whakamahia te pewa poto i te wā e whakarewa ana. He tika te ara whakarewa whaiti.
