ʻO ka super duplex stainless e like me ka duplex he microstructure hui pū ʻia o austenite a me ferrite i hoʻomaikaʻi i ka ikaika ma luna o nā pae kila ferritic a me austenitic.ʻO ka ʻokoʻa nui ʻo ka super duplex ka molybdenum kiʻekiʻe a me ka ʻike chromium e hāʻawi i ka mea i ʻoi aku ka pale corrosion.Loaʻa i ka Super duplex nā pōmaikaʻi like me kāna hoa - he haʻahaʻa haʻahaʻa ke kumu kūʻai ke hoʻohālikelike ʻia me nā māka ferritic a me austenitic like a ma muli o nā mea i hoʻonui ʻia i ka tensile a me ka ikaika hua, i nā manawa he nui kēia e hāʻawi i ka mea kūʻai aku i ke koho ʻoluʻolu e kūʻai i nā mānoanoa liʻiliʻi me ka ʻole o ka pono e hoʻololi i ka maikaʻi a me ka hana.

Nā hiʻohiʻona:
1 .Kūʻē kūʻē i ka lua a me ka ʻāʻī ʻana i loko o ka wai kai a me nā kaiapuni chloride ʻē aʻe, me ka wela pitting koʻikoʻi ma mua o 50°C
2 .ʻO ka ductility maikaʻi loa a me ka ikaika hopena ma nā mahana ambient a me ka sub-zero
3 .Kū'ē kiʻekiʻe i ka abrasion, erosion a me cavitation erosion
4 .Kūleʻa maikaʻi i ke koʻikoʻi ka pohā ʻana i ka chloride i loko o nā kaiapuni
5 .ʻAe ʻia ʻo ASME no ka noi moku kaomi
