Duplex 2507 Nānā

ʻO Duplex 2507 kahi kila kila kila super duplex i hoʻolālā ʻia no nā noi e koi ana i ka ikaika kūʻokoʻa a me ka pale ʻana i ka corrosion. ʻO Alloy 2507 he 25% chromium, 4% molybdenum, a me 7% nickel. ʻO kēia molybdenum kiʻekiʻe, chromium a me ka nitrogen ka hopena i ke kūpaʻa maikaʻi loa i ka chloride pitting a me ka hoʻouka ʻana i ka corrosion crevice a hāʻawi ka duplex structure i ka 2507 me ke kūʻē kūʻokoʻa i ka chloride stress corrosion cracking.

Pono e kaupalena ʻia ka hoʻohana ʻana o Duplex 2507 i nā noi ma lalo o 600° F (316° C). Hiki i ka hoʻonui ʻia ʻana o ka wela ke hoʻemi i ka paʻakikī a me ka pale ʻana o ka alloy 2507.

Loaʻa iā Duplex 2507 nā waiwai mechanical maikaʻi loa. Hiki ke hoʻohana pinepine ʻia kahi anana māmā o 2507 mea e hoʻokō ai i ka ikaika hoʻolālā like o kahi alloy nickel mānoanoa. ʻO ka hopena o ka mālama ʻana i ke kaumaha hiki ke hoʻemi nui i ke kumukūʻai holoʻokoʻa o ka hana.

Pale ʻino

ʻO 2507 Duplex ka mea kūpaʻa loa i ka ʻino like ʻole e nā waikawa organik e like me ka formic a me ka acetic acid. He kūpaʻa loa ia i nā ʻakika inorganic, ʻoi aku ka nui inā loaʻa nā chlorides. ʻO Alloy 2507 ka mea kūpaʻa loa i ka carbide-related intergranular corrosion. Ma muli o ka ʻāpana ferritic o ke ʻano duplex o ka alloy ua kūpaʻa loa ia i ke koʻikoʻi i ka haki ʻana o ka corrosion i loko o nā kaiapuni mehana chloride. Ma o ka hoʻohui ʻana o ka chromium, molybdenum a me ka nitrogen localized corrosion e like me ka pitting a me ka crevice attack e hoʻomaikaʻi ʻia. Loaʻa i ka Alloy 2507 ke kūpaʻa pitting kūloko.

He aha nā hiʻohiʻona o Duplex 2507?

● High kū'ē i ka chloride stress corrosion māwae
● Ka ikaika kiʻekiʻe
● ʻOi aku ka maikaʻi o ka pale ʻana i ka lua chloride a me ka ʻinoʻino
● Kūleʻa kino nui maikaʻi
● Manaʻo ʻia no nā noi a hiki i 600° F
● Haʻahaʻa haʻahaʻa o ka hoʻonui wela
● Hoʻohui o nā waiwai i hāʻawi ʻia e ka austenitic a me ka ferritic structure
● maikaʻi weldability a me ka hana
