Whakaahuatanga: He hiko maitai ātete-wera pearlitic te R306, he paninga pāhare pākawa iti-hauwai 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 whakamahana te whakarewa ki te 160 ~ 250°C i mua i te whakarewa.
Taupānga: Whakamahia mō te whakarewa i te maitai ātete-wera Cr 1% – Mo 0.5%, ā, kei raro iho i te 520℃ te pāmahana mahi, pērā i ngā paipa kōhua, ngā oko pēhanga, ngā mīhini whakamahana me ngā taputapu whakamahine 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 | ≤0.60 | 0.80 ~ 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 | ≥17 | ≥47 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 60 ~ 90 | 90 ~ 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.
