S32750 Kowiri tira ngongo Tuinga
Whakataki Hua
He kowiri tira te Super Duplex penei i te S32750, he hanganga moroiti whakauru o te austenite me te ferrite (50/50) kua pai ake te kaha ki runga i nga tohu rino ferritic me austenitic. Ko te rereketanga nui ko te Super Duplex he nui ake te molybdenum me te ihirangi chromium e nui ake ai te taonga Ko te Higher chromium hoki e whakatairanga ana i te hanganga o nga wahanga intermetallic kino, e tairongo ana ki te 475°C embrittlement na te ua o te wahanga chromium-taonga α', me te whakangao ma te sigma, chi me etahi atu waahanga i te teitei ake o te mahana.
Ko te Alloy 2507 (S32750) he nui ake te ihirangi hauota, ehara i te mea e whakatairanga ana i te hanganga o te austenite me te whakanui ake i te kaha, engari ka whakaroa ano hoki i te hanganga o nga wahanga intermetallic e nui ana ki te tuku i te tukatuka me te hanga o te reanga taarua.
Ko te ahua o te karaehe e tino pai ana te aukati waikura pūhaumāota, me te kaha pūkaha tino tiketike. He tino pai mo te whakamahi i roto i nga taiao pukuriri penei i te wai moana maataata me te paoho kei roto i te puota waikawa.
Ko nga ahuatanga Alloy 2507 (S32750) e whai ake nei:
● He tino pai te atete ki te pakaru o te waikura (SCC) i roto i nga taiao e mau ana te hauota
● He tino pai te aukati ki te waikura rua me te kapiti
● Te ātete nui ki te waikura whānui
● He tino kaha te kaha miihini
● Ko nga ahuatanga o te tinana e whai hua ana ki te hoahoa
● Te ātete teitei ki te waikura o te waikura me te ngoikore o te waikura
● He pai te weldability
Ko te S32750 i hangaia mo nga tono tono e hiahia ana kia tino kaha me te aukati waikura, ka kitea i rototukanga matū, petrochemical, me nga taputapu wai moana. Kei te whakamahia nuitia i roto i nga mahi tirotiro hinu me te hau o waho me te whakangao wera i roto i te tukatuka petrochemical/matū. He pai hoki te karaehe mo nga tono waipēhi me te taputapu taputapu i roto i nga taiao moana pārūrū.
