He mau kila kuhiliʻole kēia me ka chromium kiʻekiʻe (ma waena o 18 a me 28%) a me ka nui o ka nickel (ma waena o 4.5 a me 8%). ʻAʻole lawa ka maʻiʻo nickel e hana i kahi ʻano austenitic piha a ʻo ka hopena o ka hui ʻana o nā hale ferritic a me austenitic i kapa ʻia he duplex. ʻO ka hapa nui o nā kila duplex i loko o ka molybdenum ma kahi ākea o 2.5 - 4%.

Nā waiwai kumu

• Kū'ē kiʻekiʻe i ke koʻikoʻi corrosion māwae
• Hoʻonui kūʻē i ka hoʻouka ʻana i ka chloride ion
• ʻOi aku ka ikaika o ka tensile a me ka hoʻoulu ʻana ma mua o nā austenitic a i ʻole ferritic steels
• Maikaʻi weldability a me ka formability

Hoʻohana maʻamau

• Nā noi kai, ʻoi aku ka nui o nā mahana kiʻekiʻe
• Mea kanu desalination
• Nā mea hoʻololi wela
