S32750 (2507, F53, 1.4410) super duplex stainless steel he 25% chromium, 4% molybdenum a me 7% nickel.
ʻO S32750 ka lua-phase kila he ikaika ikaika a me ka pale ʻana i ka corrosion, ka mea i hoʻohana nui ʻia i ka hana kemika, ʻoihana petrochemical a me nā lako submarine.
ʻO S32750 ʻelua ʻāpana kila ke kūpaʻa ikaika i ka chloride corrosion, kiʻekiʻe thermal conductivity a me ka haʻahaʻa haʻahaʻa hoʻonui hoʻonui.
ʻO ka maʻiʻo kiʻekiʻe o ka chromium, molybdenum a me ka nitrogen he kiʻekiʻe ke kū'ē i ka ʻike ʻana i ka corrosion, crack corrosion a me ka corrosion maʻamau.
Loaʻa i ka S32750 ke kila lua-phase ka ikaika hopena kiʻekiʻe a ʻaʻole kūpono no ka hoʻohana ʻana i nā mahana ma luna o 570 ° c, kahi e emi ai kona paʻakikī i ka manawa.
ʻO S32750 ʻelua ʻāpana kila i hoʻohui i nā kila ferritic a me ke kila austenitic ka waiwai maikaʻi loa, no ka mea, ʻoi aku ka kiʻekiʻe o ka chromium a me ka molybdenum maʻiʻo, no laila ke kūpaʻa maikaʻi loa i ka corrosion, crevice corrosion a me ka hiki o ka corrosion like, duplex microstructure e hōʻoia i ka kila i ka hiki o ke kiʻekiʻe kū'ē i stress corrosion māwae, a me ka mechanical ikaika kiʻekiʻe.

1. Ke hoʻohālikelike ʻia me 904L, S32750 ʻelua-phase kila i ʻoi aku ka ikaika o ka corrosion kū'ē i ka dilute sulfuric acid i hui pū ʻia me nā ion chloride.
ʻO 904L kahi huila austenitic i hoʻolālā kūikawā ʻia e pale aku i ka ʻino o ka sulfuric acid maʻemaʻe.
ʻO ke kiʻekiʻe o ka chromium a me ka molybdenum maʻiʻo o S32750 pālua-phase kila e ʻoi aku ka paʻa ʻana i ka corrosion holoʻokoʻa o nā waikawa organik e like me ka waikawa a me ka acetic acid.
ʻO S32750 duplex steel hoʻi he kūpaʻa kūpaʻa ikaika i nā ʻakika inorganic, ʻoi aku ka nui o nā chlorides.
ʻAʻole hiki ke hoʻohana ʻia ka papa 316L i nā kaiapuni hydrochloric acid kahi i hiki ke hoʻopili ʻia i ka ʻino kūloko a honua paha.
Hiki ke hoʻohana ʻia ke kila kila lua S32750 i loko o ka dilute hydrochloric acid environment, me ke kūpaʻa ikaika i ka ʻike ʻana i ka pōʻino a me ka hiki ʻana o ka corrosion.
2. Intercrystalline corrosion S32750 lua-phase kila he haʻahaʻa kalapona maʻiʻo, e hoemi loa i ka pilikia o ka intercrystalline carbide ua i ka wā wela.No laila, kūpaʻa loa kēia huila i ka corrosion intercrystalline pili carbon.
3. Stress corrosion pohā: ma muli o kona kiʻekiʻe o ka mea hao, ʻoi aku ka maikaʻi o ka pale ʻana a me ka ikaika o S32750 lua-phase kila ma mua o ka 2205.
ʻO S32750 pālua - ʻoi aku ka ʻoi aku o ka pale ʻana i ke koʻikoʻi i ka hiki ʻana i ka pohā ʻino.
4, corrosion a corrosion: nui nā ala e hoʻāʻo ai i ka pale ʻana o nā huahana kila i ka hopena i loaʻa ka chloride.Hōʻike ʻia ka mahana koʻikoʻi no ka ʻino a me ka ʻino o ke kila kila kila ma 1M sodium chloride solution.
Hōʻike nā hopena hoʻokolohua like ʻole i ka S32750 pālua - ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.
5, māwae pōʻalo: nā māwae i loko o ka hale a me nā mea ʻē aʻe he aneane hiki ʻole ke pale aku i ke kila kuhiliʻole i ka corrosion i loko o ka chloride environment.2507 pālua - ʻāpana kila i ka ikaika anti - māwae corrosion hiki.
