Duplex 2507 Overview
Duplex 2507 is super duplex stainless simbi yakagadzirirwa maapplication ayo anoda yakasarudzika simba uye corrosion resistance.Alloy 2507 ine 25% chromium, 4% molybdenum, uye 7% nickel.Iyi yakakwira molybdenum, chromium uye nitrogen zvirimo zvinoguma nekupikisa kwakanyanya kune chloride pitting uye crevice corrosion attack uye duplex chimiro chinopa 2507 nekusarudzika kuramba kune chloride stress corrosion kuparuka.
Kushandiswa kweDuplex 2507 kunofanira kugumira kumashandisirwo ari pasi pe600° F (316° C).Kuwedzera kwakakwira tembiricha kuratidzwa kunogona kuderedza kuoma uye kuomarara kuramba kwealloy 2507.
Duplex 2507 ine yakanakisa michina zvivakwa.Kazhinji jeji yechiedza ye2507 zvinhu inogona kushandiswa kuwana yakafanana dhizaini simba reiyo gobvu nickel alloy.Iko kuchengetwa kunoguma muhuremu kunogona kuderedza zvakanyanya mutengo wakazara wekugadzira.
Corrosion Resistance
2507 Duplex inoshingirira zvakanyanya kune yunifomu corrosion ne organic acids senge formic uye acetic acid.Iyo zvakare inopikisa zvakanyanya kune inorganic acids, kunyanya kana iine chlorides.Alloy 2507 inopikisa zvakanyanya kune carbide-inoenderana intergranular corrosion.Nekuda kweiyo ferritic chikamu cheiyo duplex chimiro cheiyo alloy inoshingirira kushushikana nekuora kutsemuka mune inodziya chloride ine nharaunda.Kuburikidza nekuwedzera kwechromium, molybdenum uye nitrogen yenzvimbo yecorrosion senge gomba uye kurwisa kwegomba inovandudzwa.Alloy 2507 ine yakanakisa yenzvimbo pitting kuramba.
Ndeapi maitiro eDuplex 2507?
● Kunyanya kupikisa chloride stress corrosion cracking
