Irahiko Whakarewa Rino Pāmahana Iti
W707
GB/T E5015-G
AWS A5.5 E7015-G
Whakaahuatanga: He hiko maitai pāmahana-iti te W707, he paninga konutai hauwai-iti. E whakamahia ana 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 |
| ≤0.08 | ≤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 | ≥490 | ≥390 | ≥22 | ≥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 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Pānui:
1. Me tunu te hiko mō te 1 hāora i te 350℃ i mua i te mahi whakarewa;
2. Whakamātauria te whakamahi i te pūngao aho iti i te wā e whakarewa ana, e whakarewa ana i ngā paparanga maha me ngā ara maha.
