Ile oloke meji Irin alagbara

Duplex alagbara, irin ite 2205 (tun mo bi UNS S31803/S32205, ASTM A240 Iru 2205, Inox 2205, AISI 318LN, SUS 329J3L, tabi EN 1.4462) jẹ meji-alakoso (ferritic%) chrom-auste chromium-23. 2.5–3.5% molybdenum, 4.5–6.5% nickel, ati ni aijọju 0.15% nitrogen. Microstructure iwọntunwọnsi rẹ n pese apapo alailẹgbẹ ti agbara giga ati resistance ipata to dara julọ. Fun apẹẹrẹ, ite 2205 ni igbagbogbo ni iwọn ilọpo meji agbara ikore ti 316L irin alagbara, irin, gbigba awọn apẹẹrẹ lati lo pupọ tinrin, awọn apakan fẹẹrẹ laisi iṣẹ ṣiṣe rubọ.

A pese alloy ni deede ni ipo isọdọtun-ojutu (fun ASTM A240/A240M) lati ṣe idaduro eto ile oloke meji to peye. Ite 2205 maa wa alakikanju lati awọn iwọn otutu cryogenic (ni ayika -50°C) titi de iwọn +300°C; kọja ibiti o wa, brittle sigma alakoso le dagba ni welds. Awọn ohun-ini wọnyi jẹ ki ile oloke meji 2205 jẹ yiyan ti o tayọ fun awọn ohun elo eletan gẹgẹbi sisẹ kemikali, epo ti ita & gaasi, ati awọn agbegbe omi nibiti agbara giga mejeeji ati resistance ipata kiloraidi nilo.
