Waea Whakarewa ER2209 ER2553 ER2594
Whakaahuatanga Poto:
ER 2209Kua hangaia hei whakarewa i ngā maitai kore waikura takirua pērā i te 2205 (Tau UNS N31803). Ko te kaha kume teitei me te ātete pai ake ki te pakaru waikura me te poka te āhuatanga o ngā whakarewa o tēnei waea. He iti ake te ferrite o tēnei waea ki tērā o te konganuku turanga kia pai ake ai te whakarewa.
ER 2553e whakamahia ana i te nuinga o te wā hei whakarewa i ngā maitai kore waikura takirua kei roto tata ki te 25% te chromium. He hanganga moroiti 'takirua' tōna e titoa ana e te hanganga austenite-ferrite. Ko te āhuatanga o tēnei koranu takirua he kaha kume teitei, he ātete ki te pakaru waikura ahotea, ā, he ātete pai ake ki te pakaru.
ER 2594he waea whakarewa superduplex. Ko te Tau Ātete Pitting (PREN) he 40 neke atu rānei, ā, mā reira ka taea te kī ko te konganuku whakarewa he maitai kore-whakauru superduplex. Ka whakaratohia e tēnei waea whakarewa he āhuatanga matū me te āhuatanga miihini e ōrite ana ki ngā koranu superduplex i hangaia pērā i te 2507 me te Zeron 100 me ngā koranu whakarewa superduplex (ASTM A890). Ko te 2-3 ōrau te nui o te Nickel i roto i tēnei waea whakarewa hei whakarato i te ōwehenga ferrite/austenite tino pai i roto i te whakarewa kua oti. Ko te hua o tēnei hanganga he kaha kume me te kaha tuku me te ātete pai ki te SCC me te waikura pitting.
