Super Duplex alagbara bi S32750, ni a adalu microstructure ti austenite ati ferrite (50/50) eyi ti o ti dara si agbara lori ferritic ati austenitic, irin onipò. Iyatọ akọkọ ni pe Super Duplex ni molybdenum ti o ga julọ ati akoonu chromium eyiti o fun ohun elo ti o ga julọ chromium giga tun ṣe igbega dida awọn ipele intermetallic ipalara, eyiti o ni itara si 475 ° C embrittlement nitori ojoriro ti ipele chromium-ọlọrọ α, ati si embrittlement nipasẹ sigma, chi ati awọn ipele miiran ni awọn iwọn otutu ti o ga julọ.

Alloy 2507 (S32750) tun ni akoonu nitrogen ti o ga julọ, eyiti kii ṣe igbega iṣelọpọ ti austenite nikan ati mu agbara pọ si, ṣugbọn tun ṣe idaduro dida awọn ipele intermetallic to lati gba laaye sisẹ ati iṣelọpọ ti ipele ile oloke meji.

Ipele naa jẹ ijuwe nipasẹ resistance ipata kiloraidi ti o dara pupọ, ni idapo pẹlu agbara ẹrọ ti o ga pupọ. O baamu ni pataki fun lilo ni awọn agbegbe ibinu bii omi okun chlorinated gbona ati awọn media ti o ni kiloraidi ekikan.

Awọn abuda Alloy 2507 (S32750) jẹ bi atẹle:

● O tayọ resistance si wahala ipata wo inu (SCC) ni kiloraidi-ara agbegbe
● O tayọ resistance to pitting ati crevice ipata
● Idaabobo giga si ipata gbogbogbo
● Agbara ẹrọ ti o ga pupọ
● Awọn ohun-ini ti ara ti o funni ni awọn anfani apẹrẹ
● Idaabobo giga si ibajẹ ibajẹ ati rirẹ ibajẹ
● O dara weldability

S32750 jẹ apẹrẹ fun awọn ohun elo ibeere eyiti o nilo agbara iyasọtọ ati resistance ipata, eyiti o rii ninuilana kemikali, petrochemical, ati ohun elo omi okun. O ti wa ni lilo pupọ ni epo ti ilu okeere ati iṣawakiri gaasi / iṣelọpọ ati ni awọn paarọ ooru ni iṣelọpọ petrochemical / kemikali. Ipele naa tun dara fun hydraulic ati awọn ohun elo ohun elo ni awọn agbegbe oju omi otutu.
