Nānā o 2205 Duplex Stainless Steel
Hoʻohana nui ʻia ʻo Duplex 2205 stainless steel (ferritic a me austenitic) i nā noi e pono ai ke kūpaʻa maikaʻi a me ka ikaika. Ua hoʻololi ʻia ke kila kila kila S31803 ma muli o ka UNS S32205. Hāʻawi kēia papa i ke kūpaʻa kiʻekiʻe i ka corrosion.
Ma nā mahana ma luna o 300 ° C, e hoʻomāhuahua ka ua nā micro-constituent o kēia papa, a ma nā mahana ma lalo o -50 ° C e hoʻololi nā micro-constituents i ka ductile-to-brittle transition; no laila ʻaʻole kūpono kēia ʻano o ke kila kila no ka hoʻohana ʻana i kēia mau wela.

Pōmaikaʻi o Duplex Stainless Steel
l Hooikaika i ka ikaika
ʻOi aku ka ikaika o ka nui o nā papa duplex ma mua o ka austenitic a me ka ferritic stainless steel grades.
l Kiekie oolea a me ka Ductility
ʻOi aku ka maʻalahi o ka Duplex stainless steel ma lalo o ke kaomi ma mua o nā māka ferritic a hāʻawi i ka ʻoi aku ka paʻakikī. ʻOiai hāʻawi pinepine lākou i nā waiwai haʻahaʻa ma mua o nā kila austenitic, ʻoi aku ka nui o ke ʻano a me nā hiʻohiʻona o ke kila duplex ma mua o nā hopohopo.
l Kūʻai ʻino kiʻekiʻe
Ma muli o ka papa i nīnau ʻia, hāʻawi ʻia nā kila kuhili ʻole duplex (a ʻoi aku ka maikaʻi) kūʻē i ka corrosion e like me nā māka austenitic maʻamau. No nā huila me ka hoʻonui i ka nitrogen, molybdenum, a me ka chromium, hōʻike nā kila i ke kūpaʻa kiʻekiʻe i ka crevice corrosion a me ka lua chloride.
l Ke Kumukuai
Hāʻawi ka Duplex stainless steel i nā pono āpau ma luna aʻe e koi ana i nā pae haʻahaʻa o ka molybdenum a me ka nickel. ʻO ke kumu kēia he koho haʻahaʻa haʻahaʻa ma mua o ka nui o nā māka austenitic kuʻuna o ke kila kila. ʻO ka ikaika a me ka pale ʻana i ka corrosion, ʻo ia hoʻi, ʻoi aku ka lahilahi o nā ʻāpana i hana ʻia me ka stainless duplex ma mua o ko lākou mau austenitic e hāʻawi ana i nā kumukūʻai haʻahaʻa.
