S32750 Simbi Isina Musono Isina Musono

Tsananguro pfupi:

Alloy 2507, ine nhamba yeUNS S32750, imhando yesimbi ine zvikamu zviviri yakavakirwa pahurongwa hwesimbi-chromium-nickel ine chimiro chakasanganiswa cheaustenite neferrite zvakaenzana. Nekuda kwe duplex phase balance, Alloy 2507 inodzivirira ngura zvakanyanya sesimbi dzisina ngura dze austenitic dzine zvinhu zvakafanana zve alloying. Kunze kweizvozvo, ine simba rakawanda rekusunga uye kubereka pamwe nekuramba kuri nani kwe chloride SCC kupfuura dzimwe dzayo dze austenitic uku ichiramba yakasimba kupfuura dzimwe dze ferritic.

Super Duplex stainless seS32750, imhando yakasanganiswa yeaustenite neferrite (50/50) iyo yakawedzera simba kupfuura ferritic neaustenitic steel grades. Musiyano mukuru ndewekuti Super Duplex ine molybdenum yakawanda uye chromium iyo inopa zvinhu zvakawanda. Higher chromium inokurudzirawo kuumbwa kwe intermetallic phases dzinokuvadza, idzo dzinonzwa 475°C embrittlement nekuda kwekunaya kwe chromium-rich α' phase, uye embrittlement ne sigma, chi nedzimwe phases pakupisa kwakanyanya.

Alloy 2507 (S32750) inewo nitrogen yakawanda, iyo isingangobatsiri chete kuumbwa kweaustenite uye inowedzera simba, asi inononotsawo kuumbwa kwezvikamu zvepakati pesimbi zvakakwana kuti ibvumire kugadziriswa nekugadzirwa kwemhando ye duplex.

Mhando iyi inodzivirira chloride zvakanaka, pamwe chete nesimba guru remuchina. Yakakodzera kushandiswa munzvimbo dzine hukasha dzakadai semvura yegungwa ine chlorine inodziya uye ine acidic chloride.

Hunhu hweAlloy 2507 (S32750) ndehwekuti:

● Kudzivirira kwakanyanya kupwanyika kweganda (SCC) munzvimbo dzine chloride
● Kudzivirira kwakanaka kwazvo ngura inoputika uye inotsemuka
● Kusakwanisa kurwisa ngura zvakanyanya
● Simba guru kwazvo remakanika
● Zvimiro zvemuviri zvinopa zvakanakira dhizaini
● Kusakwanisa kubatwa nengura nekuora zvakanyanya
● Kugona kusundira zvakanaka

S32750 yakagadzirirwa kushandiswa kwakasimba kunoda simba rakasiyana uye kuramba ngura, izvo zvinowanikwa mumaitiro emakemikari, michina ye petrochemical, uye yemumvura yegungwa. Inoshandiswa zvakanyanya mukutsvaga/kugadzira mafuta negasi kunze kwegungwa uye muzvinhu zvinochinja-chinja kupisa mu petrochemical/chemical processing. Mhando iyi yakakodzerawo kushandiswa kwe hydraulic uye zvishandiso munzvimbo dzinopisa dzegungwa.
