GB/T E6016-B3
AWS A5.5 E9016-B3
Whakaahuatanga: He hiko maitai ātete-wera pearlitic te R406, he paninga pāhare pākawa iti-hauwai kei roto ko te 2.5% Cr – 1% 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 ~ 200°C i mua i te whakarewa.
Whakamahinga: Whakamahia mō te whakarewa i ngā hanganga maitai ātete wera Cr2.5Mo pearlitic, pērā i ngā paipa pāmahana teitei me te pēhanga teitei me ngā pāmahana mahi i raro i te 550 °C, ngā mīhini matū hangai, me ngā taputapu pakaru hinu.
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 |
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 |
| WhakarewaInāianei （A） | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 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.
