Ngā Āhuatanga Matua o ngā ngongo ASTM A335 P91 Momo 2
Ko te ASTM A335 P91 Momo 2 he maitai koranu chrome-moly e mōhiotia ana mō tōna kaha tino pai, tōna ātete ki te pāmahana, me tōna kaha ngoki. Kua whakarōpūtia hei maitai ferritic whakarei ake i te kaha ngoki (CSEF), he mea tino pai mō ngā tono pāmahana teitei me te pēhanga teitei. Ka pāngia te rauemi e tētahi tukanga maimoatanga wera motuhake:

Te whakataurite i te 1050 °C.

Te whakamatao hau ki te 200 °C.

Te whakamahana i te 760 °C.

Ka whakarei ake tēnei tukanga i tōna kaha ngokingoki me tōna roa, ka waiho hei kōwhiringa pai rawa atu mō ngā taiao uaua.

Ngā tono o ngā ngongo maitai ASTM A335 P91
E whakamahia whānuitia ana te P91 i roto i ngā ahumahi e hiahia ana ki ngā rauemi e kaha ana ki te tu atu i ngā pāmahana me ngā pēhanga tino kino. Ko ngā whakamahinga noa ko:

Te whakaputa hiko: Ngā poiha, ngā raina whakamahana anō, me ngā tipu huringa whakakotahi.

Ngā whare hanga hinu: Ngā whakamahana, ngā taputapu tukatuka hau, me ngā ratonga mara hinu.

Ngā pūnaha paipa pāmahana-tiketike: He pai mō ngā mahi piko, whakapuru, me te whakarewa.

Te Hanganga Matū o ngā Ngongo Rino ASTM A335 P91
Mā te hanganga matū o P91 ka tino pai ake tana mahi:

Waro: 0.08% – 0.12%

Konupora: 0.30% – 0.60%

Konupora: 8.00% – 9.50%

Molibdenum: 0.85% – 1.05%

Vanadium: 0.18% – 0.25%

Hauota: 0.030% – 0.070%

Ngā huānga kē atu: Te nikara, te konumohe, te korumiuma, te taitēniuma, me te zirconium i roto i ngā rahinga kua whakaritea.

Ngā Āhuatanga Mīhini
Kaha Kume: Iti rawa 85,000 PSI (585 MPa).

Kaha Hua: Te iti rawa 60,000 PSI (415 MPa).

Ngā Ngongo Rino ASTM A335 P91 mō te Whakarewa me te Maimoatanga Wera
Me piri pono ki ngā tikanga mō te whakarewa P91 kia mau tonu ai ōna āhuatanga:

Te whakamahana-mua: He mea nui hei ārai i te pakaru i puta mai i te hauwai.

Te whakahaere pāmahana i waenga i ngā whakawhiti: Ka tiakina mā te whakamahi i ngā pūnaha whakamahana arataki hou.

Maimoatanga wera i muri i te whakarewanga (PWHT): He mea nui kia tutuki ai te hanganga moroiti e hiahiatia ana, kia kore ai hoki e rahua.

Ngā irahiko whakarewa: Me ōrite te hanganga o te rauemi matua.
