Iipropati ze-S32750 zezinto eziphathekayo
I-2507 i-super duplex steel stainless kunye nokumelana nokugqwala okungcono kunye namandla ngaphezu kwe-2205. Idibanisa iipropati ezininzi ezincedo kwiintsimbi ezininzi ze-ferritic kunye ne-austenitic kwaye, ngenxa ye-chromium ephezulu kunye nomxholo we-molybdenum, inokumelana okuhle kakhulu kwi-uniform, pitting and crevice corrosion.Isakhiwo sesigaba sesibini siqinisekisa ukuba isinyithi sinokuchasana okuphezulu koxinzelelo lwe-corrosion cracking kunye namandla aphezulu omatshini.
Umxholo ophezulu we-chromium kunye ne-molybdenum yenza ukuba ibe nokuchasana okunamandla kwi-corrosion yonke ye-organic acids efana ne-formic acid, i-acetic acid, njl.Xa ithelekiswa ne-904L, eyilelwe ngokukodwa ukuxhathisa iasidi yesulfuric esulungekileyo, i-2507 inokumelana ne-corrosion eyomeleleyo kwi-asidi ye-sulfuric exutywe ne-chloride ion.
Ibanga le-316L alinakusetyenziswa kwindawo ye-hydrochloric acid, ingaba phantsi kwe-corrosion yendawo okanye i-corrosion jikelele, ngelixa i-2507 ingasetyenziselwa kwi-diluted hydrochloric acid environment, kunye ne-anti-spot eqinile kunye ne-anti-crevice corrosion.Umxholo ophantsi wekhabhoni we-2507 unciphisa kakhulu umngcipheko we-carbide precipitation kwi-intergranular ngexesha lonyango lokushisa kwaye, ngoko ke, lichasene kakhulu ne-carbide-related intergranular corrosion.
I-2507 inamandla aphezulu oxinzelelo, amandla empembelelo kunye ne-coefficient ephantsi yokwandiswa kwe-thermal kunye ne-conductivity ephezulu ye-thermal, ezi mpawu zifanelekile kwiindawo ezininzi zesakhiwo kunye neengxenye zomatshini.
I-2507 akufuneki ibekwe kwindawo yobushushu engaphezulu kwe-300 ℃ ixesha elide, enokuthi yenze buthathaka ukuqina kwayo.
I-Corrosion Resistance ye-S32750 Material
1. Ukumelana nokubola
Ichromium ephezulu kunye nomxholo we-molybdenum we-SAF 2507 yenza ukuba ixhathise ngakumbi kwi-corrosion enkulu ye-organic acids efana ne-fomic acid kunye ne-acetic acid.I-SAF 2507 ialloy nayo inokumelana okuqinileyo ne-inorganic acids, ngakumbi ezo zinekloridi.ukumelana nomhlwa.
Xa kuthelekiswa ne-904L, i-SAF2507 inokumelana ne-corrosion eyomeleleyo kwi-asidi ye-sulfuric exutywe ne-chloride ion.I-904L yi-alloy kwi-austenitic state, eyenzelwe ngokukodwa ukuxhathisa i-corrosion ecocekileyo ye-sulfuric acid.
Ibanga le-316L alinakusetyenziswa kwindawo ye-hydrochloric acid, ingaba phantsi kwe-corrosion yendawo okanye i-corrosion jikelele.I-SAF2507 ingasetyenziswa kwimo engqongileyo ye-hydrochloric acid, ene-anti-spot eyomeleleyo kunye ne-anti-crevice corrosion.
2. I-Intergranular Corrosion
Umxholo ophantsi wekhabhoni we-SAF 2507 unciphisa kakhulu umngcipheko we-intergranular carbide precipitation ngexesha lonyango lokushisa, ngoko ke, le alloy ichasene kakhulu ne-carbide-related intergranular corrosion.
3. Uxinzelelo lwe-corrosion cracking
Ubume be-duplex be-SAF 2507 buyenza ixhathise kakhulu kuxinzelelo lokuqhekeka kwe-corrosion.Ngenxa yomxholo we-alloy ephezulu, ukuxhathisa ukubola kunye namandla e-SAF 2507 kungcono kune-2205.
Iintanda ziphantse zingenakuphepheka ekwakhiweni, njl., Ezenza insimbi engenasici ichaphazeleke ngakumbi kwi-corrosion kwindawo ye-chloride.I-SAF 2507 inesakhono esomeleleyo sokuxhathisa i-crack corrosion.I-isocorrosion curve ye-SAF 2507 kwi-asidi ye-sulfuric equkethe i-2000ppm i-chloride ion 0.1 mm / ngonyaka;isocorrosion curve kwi-hydrochloric acid 0.1 mm / ngonyaka.
I-S32205 iMimandla yeSicelo seMathiriyeli
I-2507 insimbi engenasici isetyenziswa kwishishini leoli kunye negesi;offshore Shipotian amaqonga oyile (iityhubhu zokutshintshisa ubushushu, ukucocwa kwamanzi kunye neenkqubo zokubonelela ngamanzi, iinkqubo zokukhusela umlilo, iinkqubo zokutshiza amanzi, iinkqubo zokuzinzisa amanzi; izixhobo zepetrochemical; izixhobo zokukhupha ityuwa (i-desalination) (kunye nezixhobo kwimibhobho yoxinzelelo oluphezulu, imibhobho yamanzi olwandle); kunye namacandelo ezakhiwo ezifuna ukomelela okuphezulu kunye nokuxhathisa okuphezulu kwe-corrosion, ukutshisa (ukukhupha) izixhobo zokucoca igesi.
Imibhobho yoshishino lwemichiza, izikhongozeli, abatshintshi bobushushu, imibhobho yamanzi olwandle kwizityalo zokukhupha ityuwa, izixhobo ze-oyile negesi yoshishino, inkqubo yombane ye-flue gas desulfurization, izixhobo zokuhlamba, iinqaba zokufunxa, iitanki zolwelo lwekhemikhali.
