Ngongo Kowiri tira S32750
Whakataki Hua
Ko te kowiri tira Super Duplex, pērā i te S32750, he hanganga ranu o te austenite me te ferrite (50/50) kua pai ake te kaha i ngā momo maitai ferritic me te austenitic. Ko te rerekētanga matua ko te nui ake o te molybdenum me te chromium o Super Duplex e nui ake ai te rauemi. Ko te chromium teitei ake ka whakatairanga i te hanganga o ngā āhuahanga intermetallic kino, e tairongo ana ki te pakarukaru 475°C nā te maturuturunga iho o te āhuahanga α' whai-chromium, me te pakarukaru e te sigma, chi me ētahi atu āhuahanga i ngā pāmahana teitei ake.
He nui ake te hauota o te koranu 2507 (S32750), e kore e whakatairanga noa i te hanganga o te austenite me te whakanui ake i te kaha, engari ka whakaroa hoki i te hanganga o ngā wāhanga intermetallic kia taea ai te tukatuka me te hanga i te taumata takirua.
He tino pai te ātete o tēnei momo ki te waikura o te konukōre, me te kaha ā-ringa tino teitei. He tino pai mō te whakamahi i roto i ngā taiao kaha pērā i te wai moana mahana kua whakakīia ki te konukōre me ngā mea kei roto he konukōre waikawa.
Ko ngā āhuatanga o te Alloy 2507 (S32750) e whai ake nei:
● He ātete tino pai ki te pakaru waikura ahotea (SCC) i roto i ngā taiao whai pūhaumāota
● He ātete tino pai ki te waikura o ngā poka me ngā kapiti
● Te ātete nui ki te waikura whānui
● Tino kaha ā-mīhini
● Ngā āhuatanga ā-tinana e whakarato ana i ngā painga hoahoa
● Te ātete nui ki te waikura me te ngenge o te waikura
● He pai te āhua o te whakarewa
Kua hangaia te S32750 mō ngā tono uaua e hiahia ana ki te kaha tino pai me te ātete ki te waikura, e kitea ana i roto itukanga matū, ngā taputapu matū hinu, me te wai moana. He whānuitia te whakamahinga i roto i te tūhuratanga/whakaputa hinu me te hau i tai moana, me ngā whakawhiti wera i roto i te tukatuka matū hinu/matū. He pai hoki te momo mō ngā tono waipēhi me ngā taputapu i roto i ngā taiao moana pārūrū.
