Irahiko Whakarewa Rino Ātete Wera Molybdenum me te Chromium Molybdenum
R306Fe
GB/T E5518-B2
AWS A5.5 E8018-B2
Whakaahuatanga: He hiko maitai ātete-wera pearlitic te R306Fe, he paura rino me te paninga momo hauwai pāhare pākawa iti kei roto ko te 1% Cr – 0.5% Mo. Ka taea te whakamahi i te AC me te DC, ā, ka taea te whakarewa i ngā tūranga katoa me te mahi pewa poto. Ko te whakamahana o mua o te whakarewa me te pāmahana i waenga i ngā paparanga he 160 ~ 250 °C i te wā whakarewa.
Taupānga: Whakamahia mō te whakarewa i te maitai ātete wera pearlitic 1%Cr – 0.5%Mo (pērā i te 15CrMo), pērā i ngā paipa mata whakamahana poihau me te pāmahana mahi i raro i te 550°C, ngā paipa mamaoa me ngā oko pēhanga me te pāmahana mahi i raro i te 520°C, me ētahi atu. Ka taea te whakamahi mō te whakarewa i ngā whakarewa maitai 30CrMnSi.
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 1.00 ~ 1.50 | 0.40 ~ 0.65 | ≤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 | ≥540 | ≥440 | ≥47 | ≥27 |
| Kua whakamatauria | 550 ~ 640 | ≥450 | 20 ~ 28 | 105 ~ 150 |
Te nui o te hauwai horapa o te konganuku kua whakatakotoria: ≤6.0mL/100g (tikanga kariserina)
Tirotiro hihi-X: tohu I
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 100 ~ 130 | 140 ~ 180 | 180 ~ 210 |
Pānui:
1. Me tunu te hiko mō te 1 hāora i te pāmahana tata ki 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.
