Irahiko Whakarewa Rino Ātete Wera Molybdenum me te Chromium Molybdenum
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Whakaahuatanga: He hiko rino ātete-wera pearlitic te R407, he paninga konutai hauwai-iti kei roto ko te 2.5% Cr – 1% Mo. Whakamahia te DCEP (hiko hiko au tika) ā, ka taea te whakarewa i ngā tūranga katoa. Me whakamahana te whakarewa ki te 200 ~ 300°C i mua i te whakarewa.
Taupānga: Whakamahia mō te whakarewa i ngā paipa pāmahana teitei me te pēhanga teitei me te pāmahana mahi i raro i te 550°C, ngā mīhini matū hangai, ngā taputapu pakaru hinu, me ētahi atu.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
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) Te Mahana Noa. |
| Kua whakamanahia | ≥590 | ≥490 | ≥15 | ≥47 |
| Kua whakamatauria | 600 ~ 680 | ≥500 | 18 ~ 21 |
Te nui o te hauwai horapa o te konganuku kua whakatakotoria: ≤4.0mL/100g (tikanga kariserina)
Tirotiro hihi-X: tohu I
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 60 ~ 90 | 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. 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.
