ER2209 ER2553 ER2594 Welding Wire
Tlhaloso e Khutšoanyane:
ER 2209e etselitsoe ho chesella litšepe tse sa hloekang tse duplex joalo ka 2205 (Nomoro ea UNS N31803). Matla a phahameng a tsitsipano le khanyetso e ntlafetseng ea khatello ea maikutlo, ho phunyeha ha corrosion le pitting li tšoantšetsa li-welds tsa terata ena. Mohala ona o tlase ka ferrite ha o bapisoa le oa tšepe ea motheo e le hore o ka khona ho chesehela hantle.
ER2553e sebelisoa haholo-holo ho cheselletsa litšepe tse sa jeleng tse duplex tse nang le hoo e ka bang 25% ea chromium. E na le "duplex" microstructure e nang le austenite-ferrite matrix. Alloy ena ea duplex e tšoauoa ka matla a phahameng a ho tsieleha, ho hanyetsa khatello ea maikutlo ho senyeha ha kutu le ho ntlafala ho hanyetsa ho pitting.
ER2594ke superduplex wire welding. Pitting Resistance Equivalent Number (PREN) ke bonyane 40, kahoo e lumella tšepe ea weld ho bitsoa superduplex stainless steel. Mohala ona oa tjheseletsa o fana ka litšobotsi tse tšoanang tsa k'hemistri le thepa ea mochini ho li-alloys tse entsoeng ka superduplex tse kang 2507 le Zeron 100 hammoho le li-alloys tsa superduplex casting (ASTM A890). Terata ena ea tjheseletsa e kentsoe liperesente tse 2-3 ho Nickel ho fana ka tekanyo e nepahetseng ea ferrite/austenite ho weld e felileng. Sebopeho sena se etsa hore ho be le tsitsipano e phahameng le ho fana ka matla hammoho le khanyetso e phahameng ea SCC le kutu ea likoti.
