Ko te paerewa A335 (ASTM A335/ASME S-A335) he whakaritenga ā-ao mō ngā paipa maitai kore hononga maitai koranu ferritic e whakamahia ana i roto i ngā taiao pāmahana teitei me te pēhanga teitei. He whānuitia te whakamahinga i roto i ngā ahumahi matū hinu, hiko (wera/karihi), pōro me te whakamahine. He tino kaha te pāmahana teitei o ngā paipa maitai i raro i tēnei paerewa, he ātete ki te ngoki me te waikura, ā, he pai mō ngā āhuatanga mahi tino kino.
Ngā rauemi noa me te hanganga matū o te paerewa A335
Ka wehewehea ngā rauemi A335 e ngā tau "P", ā, he rerekē ngā momo e tika ana mō ngā pāmahana me ngā taiao waikura rerekē:
| Tau | Ngā wāhanga matū matua | Ngā Āhuatanga | Te pāmahana e tika ana |
| A335 P5 | Kr 4-6%, Mo 0.45-0.65% | Ātete ki te waikura whanariki me te ngokingoki i ngā pāmahana reo | ≤650°C |
| A335 P9 | Kr 8-10%, Mo 0.9-1.1% | He ātete ki te waikura pāmahana teitei, ā, he kaha teitei anō hoki | ≤650°C |
| A335 P11 | Kr 1.0-1.5%, Mo 0.44-0.65% | He pai te kaha whakarewa me te kaha pāmahana-waenga | ≤550°C |
| A335 P12 | Kr 0.8-1.25%, Mo 0.44-0.65% | He rite ki te P11, he kōwhiringa ōhanga | ≤550°C |
| A335 P22 | Kr 2.0-2.5%, Mo 0.9-1.1% | Te ārai i te waikura hauwai, e whakamahia whānuitia ana i roto i ngā kohua teihana hiko | ≤600°C |
| A335 P91 | Kr 8-9.5%, Mo 0.85-1.05% | Kaha tino teitei, e pai ana mō ngā waeine tino kaha | ≤650°C |
| A335 P92 | P91 + W | Te ātete pāmahana teitei ake, e tika ana mō ngā waeine tino-tino nui | ≤700°C |
Ngā horopaki tono o ngā paipa maitai A335
1. Ahumahi hinu matū
A335 P5/P9: ngā waeine pakaru whakatere i roto i ngā whare whakapai hinu, ngā paipa kei roto he whanariki pāmahana teitei.
A335 P11/P12: ngā whakawhiti wera, ngā paipa tuku mamaoa pāmahana-waenga.
2. Ahumahi hiko (hiko wera/hiko karihi)
A335 P22: Ngā paipa korohū matua me ngā pane o ngā tipu hiko wera tuku iho.
A335 P91/P92: Ngā waeine tino taikaha/tino taikaha, ngā paipa pēhanga teitei o te mana karihi.
3. Ngā kohua me ngā oko pēhanga
A335 P91: Ngā wāhanga pāmahana-tiketike o ngā poiha whai hua-tiketike o ēnei rā.
A335 P92: Ngā paipa ātete pāmahana teitei mō ngā kohua teitei ake te tawhā.
Me pēhea te whiriwhiri i te rauemi A335 tika? Ngā whakaritenga pāmahana:
Ngā whakaritenga pāmahana:
≤550°C: P11/P12
≤650°C: P5/P9/P22/P91
≤700°C: P92
Taiao waikura:
Waenga kei roto te whanariki → P5/P9
Taiao waikura hauwai → P22/P91
Te utu me te kaha:
Kōwhiringa ōhanga → P11/P12
Ngā whakaritenga kaha teitei → P91/P92
Ngā paerewa ōrite o te ao mō ngā paipa maitai A335
| A335 | （EN） | （JIS） |
| P11 | 13CrMo4-5 | STPA23 |
| P22 | 10CrMo9-10 | STPA24 |
| P91 | X10CrMoVNb9-1 | STPA26 |
Ngā Pātai Auau
P1: He aha te rerekētanga i waenganui i te A335 P91 me te P22?
P91: He nui ake te ihirangi chromium me te molybdenum, he kaha ake te ātete ki te ngokingoki, he pai mō ngā waeine tino tairongo.
P22: He iti ake te utu, he pai mō ngā kohua tipu hiko tuku iho.
Q2: Me whakamahana te paipa maitai A335?
E hiahiatia ana te maimoatanga whakataurite + whakamahana, ā, me tino whakahaere hoki te tere whakamatao o te P91/P92.
P3: He pai ake a A335 P92 i a P91?
He nui ake te ātete pāmahana o te P92 (≤700°C) nā te mea kei roto te tungsten (W), engari he nui ake anō hoki te utu.
He rauemi matua te paipa maitai koranu kore-ira paerewa A335 i raro i ngā āhuatanga pāmahana tiketike me te pēhanga tiketike. He rerekē ngā rauemi (pēnei i te P5, P9, P11, P22, P91, P92) e tika ana mō ngā āhuatanga rerekē. I te wā e whiriwhiri ana, me whai whakaaro whānui ki ngā āhuatanga pāmahana, te waikura, te kaha me te utu, me te tirotiro hoki ki ngā paerewa ōrite o te ao (pēnei i te EN, JIS).
