SUPER DUPLEX • UNS S32750 • WNR 1.4410
ʻO ka Super Duplex stainless e like me S32750, he microstructure hui ʻia o austenite a me ferrite (50/50) i hoʻomaikaʻi i ka ikaika ma luna o nā māka kila ferritic a me austenitic. ʻO ka ʻokoʻa nui ʻo ia ka Super Duplex he molybdenum kiʻekiʻe a me ka ʻike chromium e hāʻawi i ka mea i ʻoi aku ka pale corrosion ma mua o nā māka duplex maʻamau.Hoʻohui ka microstructure duel phase balance i ka ikaika kiʻekiʻe me ke kūʻai ʻana i ka corrosion maikaʻi loa ma nā wahi chloride kiʻekiʻe. Loaʻa i ka Super Duplex nā pōmaikaʻi like me kona hoa - ʻoi aku ka haʻahaʻa o ke koina hoʻohuihui ke hoʻohālikelike ʻia me nā māka ferritic a me austenitic like me nā mea hana e pale ai i ka corrosion i loko o ka chloride i loko o nā kaiapuni ma muli o ka piʻi ʻana o ka tensile a me ka ikaika hua. I nā manawa he nui, hāʻawi kēia i ka mea kūʻai aku i ke koho ʻoluʻolu o ke kūʻai ʻana i nā mānoanoa liʻiliʻi me ka ʻole o ka pono e hoʻololi i ka maikaʻi a me ka hana.
