Duplex UNS S31803
Bayanin Fasaha na Duplex UNS S31803
Dubawa
Duplex shine austenitic ferritic Iron Chromium-Nickel gami da ƙari na Molybdenim. Yana da kyakkyawan juriya ga rami, ƙarfin ƙarfi mai ƙarfi da juriya mai ƙarfi ga lalatawar damuwa a matsakaicin yanayin zafi zuwa na baƙin ƙarfe na austenitic na al'ada.
Duplex abu ne mai kusan daidai adadin austenite da ferrite. Waɗannan suna haɗuwa da kyakkyawan juriya na lalata tare da babban ƙarfi. Kaddarorin injina sun kusan ninki biyu na ƙarfe na austenitic guda ɗaya kuma juriya ga lalatawar damuwa ya fi dacewa da nau'in bakin karfe 316 a cikin maganin chloride. Abun Duplex yana da jujjuyawar ductile / gaggautsa a kusan -50°C. Yawan amfani da zafin jiki yawanci ana iyakance shi zuwa matsakaicin zafin jiki na 300 ° C don amfani mara iyaka saboda ƙullawa.
