◆F51 (31803) ʻo ia ka duplex stainless steel i hoʻohana nui ʻia, i hoʻohana nui ʻia i ka ʻaila ʻawaʻawa a me ka hoʻomaʻamaʻa kinoea, i ka hoʻomaʻemaʻe ʻana i ka aila, kemika, fertilizer, petrochemical a me nā māla ʻē aʻe, no ka hana ʻana i nā mea hoʻololi wela, condensing coolers, etc., ka mea i maʻalahi i ka luaʻi ʻana a me ke koʻikoʻi o ka ʻino o nā mea paʻi. Ma kahi o 304L, 316L austenitic stainless steel.
◆F53 (S32750) he super duplex stainless steel me ka nitrogen i hoʻohui ʻia, ka mea i hoʻohana nui ʻia i nā mea kemika, petrochemical a me nā mea moana e koi ai i ka ikaika kūikawā a me ka pale ʻana i ka corrosion.
◆F55 (S32760) mea he super duplex kuhiliʻole kila me ka ikaika kiʻekiʻe, kiʻekiʻe kū'ē i chloride localized corrosion a stress corrosion, a weldable.
ʻO ◆329 (S32900) maikaʻi ke kūpaʻa o ka oxidation, ka pale ʻana i ka corrosion, ka ikaika kiʻekiʻe, a kūpono hoʻi i nā wahi e like me ke kūpaʻa ʻana o ke kai.
◆A4 kila (0Cr17Mn13Mo2N) mea he lua-phase kila, a me kona corrosion kū'ē 'oi aku ka maikaʻi ma mua o ka hoʻohana mau austenitic kila me Mo maʻiʻo o 2% -3%. Hiki ke hoʻohana ʻia i nā mea kanu liʻiliʻi liʻiliʻi, nā lako urea piha, etc.
◆S31050 he kiʻekiʻe kū'ē i ka chloride stress corrosion māwae, maikaʻi kū'ē i pitting corrosion a crevice corrosion.
◆U3 he anti-scouring a me ka anti-corrosion waiwai, a ua hoʻohana pinepine ia e hana i ka valve cores, valve noho a me na mea e ae o loko.
Hoʻohana nui ʻia ʻo ◆HD i ka ʻoihana uila, ʻoihana photoelectric, ʻoihana petrochemical, ʻoihana kaʻa a me nā mea hoʻoponopono wikiwiki ʻē aʻe.
◆C4 kūpono no ka nui-scale vertical mixers, mixers, mixers, horizontal mixers a me nāʻoihana mīkini'ē aʻe.
◆DS-2 i corrosion kū'ē i ke kiʻekiʻe wela concentrated sulfuricʻakika, a ua kūpono no ka mīkini 'oihana i kiʻekiʻe wela concentrated sulfuricʻakikaʻoihana.
