Kayayyakin Injini:
• Duplex Bakin Karfe suna da kusan ninki biyu ƙarfin yawan amfanin takwaransu na austenitic maki.
• Wannan yana ba masu zanen kayan aiki damar yin amfani da kayan ma'auni na bakin ciki don gina jirgin ruwa!

Duplex bakin karfe fa'ida:
1. Idan aka kwatanta da austenitic bakin karfe
1) Ƙarfin yawan amfanin ƙasa ya fi sau biyu fiye da na bakin karfe na austenitic na yau da kullun, kuma yana da isasshen ƙarfin filastik da ake buƙata don yin gyare-gyare. Kauri daga cikin tanki ko jirgin ruwa da aka yi da duplex bakin karfe yana da 30-50% ƙasa da na bakin karfe austenitic da aka saba amfani da shi, wanda ke da fa'ida don rage farashin.
2) Yana da kyau kwarai juriya ga danniya lalata fatattaka, musamman a cikin yanayi dauke da chloride ions, ko da duplex gami tare da mafi ƙasƙanci gami abun ciki yana da mafi girma juriya ga danniya lalata fatattaka fiye da austenitic bakin karfe. Lalacewar damuwa babbar matsala ce wacce bakin karfe na austenitic na yau da kullun yana da wahalar warwarewa.
3) Mafi yawan 2205 duplex bakin karfe da aka yi amfani da shi a yawancin kafofin watsa labaru yana da mafi kyawun juriya fiye da 316L austenitic bakin karfe na yau da kullum, yayin da super duplex bakin karfe yana da juriya na lalata. A wasu kafofin watsa labarai, kamar acetic acid da formic acid. Yana iya ma maye gurbin babban-alloy austenitic bakin karfe har ma da lalata-resistant gami.
4) Yana da kyau juriya ga lalata gida. Idan aka kwatanta da austenitic bakin karfe tare da wannan gami abun ciki, yana da mafi kyau juriya juriya da lalata gajiya juriya fiye da austenitic bakin karfe.
5) Bakin karfe na austenitic yana da ƙarancin haɓakar haɓakawa na faɗaɗa madaidaiciya kuma yana kusa da ƙarfe na carbon. Ya dace da haɗin gwiwa tare da ƙarfe na carbon kuma yana da mahimmancin aikin injiniya, kamar samar da faranti mai haɗaka ko linings.

2. Idan aka kwatanta da ferritic bakin karfe, da abũbuwan amfãni daga duplex bakin karfe ne kamar haka:
1) The m inji Properties ne mafi girma fiye da na ferritic bakin karfe, musamman filastik tauri. Ba mai kula da brittleness kamar ferritic bakin karfe.
2) Bugu da ƙari ga juriya na lalata danniya, sauran juriya na lalata na gida sun fi ferritic bakin karfe.
3) Cold aiki tsari yi da sanyi kafa yi ne da yawa fiye da ferritic bakin karfe.
4) A waldi yi ne da yawa fiye da na ferritic bakin karfe. Gabaɗaya, ba a buƙatar maganin zafi bayan preheating ba tare da walda ba.
5) Kewayon aikace-aikacen ya fi na bakin karfe na ferritic.

Aikace-aikaceSaboda ƙarfin ƙarfin ƙarfe na duplex, yana kula da adana abu, kamar rage kaurin bangon bututu. Amfani da SAF2205 da SAF2507W azaman misalai. SAF2205 ya dace don amfani a cikin mahalli mai ɗauke da chlorine kuma ya dace don amfani dashi a cikin matatar mai ko wasu kafofin watsa labarai masu gauraye da chloride. SAF 2205 ya dace musamman don amfani a cikin masu musanya zafi mai ɗauke da chlorine mai ruwa-ruwa ko ruwa mai sanyi azaman matsakaicin sanyaya. Har ila yau, kayan ya dace da tsarma maganin sulfuric acid da tsantsar kwayoyin acid da gaurayawan sa. Kamar su: bututun mai a masana'antar mai da iskar gas: zubar da danyen mai a matatun mai, tsarkake iskar gas mai dauke da sulfur, kayan aikin gyaran ruwa; tsarin sanyaya ta yin amfani da ruwa mai laushi ko mafita mai ɗauke da chlorine.
