I-S31803 Duplex Stainless Steel: I-Superior Corrosion Resistance kunye namandla aphezulu osetyenziso lwezoShishino

I-S31803, ekwabizwa ngokuba yi-Duplex 2205 okanye i-F60, libakala eliqwalaselwa kakhulu le-duplex yensimbi engenasici kwimarike yehlabathi. Eyaziwayo phantsi kweNkqubo yokuBala eManyeneyo (i-UNS), esi sixhobo sixabiswa ngenxa yokumelana nokugqwala okungaqhelekanga, amandla aphezulu omatshini, kunye nokusebenza ngeendlela ezahlukeneyo kwiindawo ezinzima.

Ukubunjwa kweMichiza engundoqo kunye noLwakhiwo

I-S31803 i-duplex yensimbi engenasici ifaka umxube olungelelanisiweyo wezinto ezidibeneyo ezihambisa iimpawu zayo ezibalaseleyo:

• I-Chromium (Cr):Malunga ne-22% - Yongeza ukuxhathisa ukudleka, ngakumbi ngokuchasene nemingxunya kunye nokuhlwa kwemingxuma.

• I-Nickel (Ni):Malunga ne-5.0-6.0% - Ukuphucula ukuqina kunye ne-ductility.

• I-Molybdenum (Mo):Ngokumalunga ne-3.0% - Ikhuthaza ukuxhathisa kwi-corrosion yendawo, ngakumbi kwiindawo ezityebileyo ze-chloride.

• I-nitrogen (N):Ngokumalunga ne-0.18% - Yandisa amandla kwaye igalelo kuxinzelelo lwe-corrosion resistance.

I-microstructure ekhethekileyo yesigaba sesibini, esidibanisa izigaba ze-ferritic kunye ne-austenitic, iphumela kwiipropathi zoomatshini eziphantse zibe kabini ezo zentsimbi eziqhelekileyo ze-austenitic ezingenasici ngelixa zigcina i-ductility egqwesileyo kunye nokuqina.

IiPropati eziBalaseleyo kunye neeNzuzo

Ukomelezwa koKuchasa ukonakala

I-S31803 iyagqwesa ekuxhathiseni iintlobo ezahlukeneyo zomhlwa, kuquka:

• I-Pitting and Crevice Corrosion:I-chromium yayo ephezulu kunye nomxholo we-molybdenum ivumela ukuba isebenze ngokukodwa kwiindawo ze-chloride.

• Uxinzelelo lwe-Corrosion Cracking:Isakhiwo se-duplex sinikeza ukuchasana okwandisiweyo ekuqhekekeni phantsi koxinzelelo, nangona xa kubonakaliswe kumajelo ahlaselayo.

Ukomelela koomatshini abaPhezulu

• Amandla Okuqina Okuphakamileyo:Ngokuqhelekileyo, amandla e-tensile ye-S31803 adlula i-500 MPa, okwenza kube yinto efanelekileyo kwizicelo zoxinzelelo oluphezulu.

• Ukuqina okuphuculweyo:I-microstructure elungeleleneyo ayiqinisekisi nje kuphela amandla kodwa ikwaqinisekisa ukuqina okuthembekileyo kunye ne-ductility, ebalulekileyo kwiimeko zemizi-mveliso.

UkuWeldability okugqwesileyo

Nangona ingqwalasela ekhethekileyo ifunekayo ngexesha le-welding ukuze ugweme ukuthotywa kwendawo echaphazelekayo ukushisa, iindlela ezifanelekileyo ze-welding kunye nonyango lwe-post-weld lunokuqinisekisa ukuxhamla okunamandla, angenasiphako. Oku kwenza i-S31803 ibe lukhetho olusebenzayo kuyo yomibini imveliso eyenziweyo kunye nomsebenzi wokulungisa

Izicelo zoShishino

I-S31803 i-duplex yensimbi engenasici ifumana ukusetyenziswa okubanzi kumashishini ahlukeneyo ngenxa yokudityaniswa kwayo okulinganayo kwamandla kunye nokumelana nokubola. Iindawo ezingundoqo zesicelo ziquka:

• Isixhobo sokuLungiselela imichiza:Ilungele i-reactors, iitanki zokugcina, kunye neenkqubo zemibhobho apho ukuxhathisa kwiikhemikhali ezinobundlobongela kufuneka.

• Ishishini leoli negesi:Isetyenziswe kakhulu kwimibhobho, iivalve, kunye nokufakelwa, ngakumbi phantsi kweemeko eziphezulu kunye ne-high-chloride.

• Ubunjineli baseLwandle kunye noKwakha iinqanawa:Ukuxhathisa kwayo kwi-corrosion yamanzi etyuwa kuyenza ifaneleke kwizakhiwo ezingaselunxwemeni, izixhobo zaselwandle, kunye nezinye iinkqubo zaselwandle.

• Izixhobo zokuvelisa amandla:Ukuqeshwa kumaziko ombane nakwizixhobo zenyukliya apho imfezeko yesakhiwo kunye nokusebenza kwexesha elide kubaluleke kakhulu.

• Ulwakhiwo kunye nezixhobo zoYilo:Ukugqitywa kwayo okukhangayo kunye nokuqina kwayo kuye kwakhokelela ekusetyenzisweni kwayo kwizakhiwo zanamhlanje kunye nezicelo zobuhle

   

Ukuthotyelwa kweMigangatho yeHlabathi

I-S31803 i-duplex yensimbi engenasici ihambelana nemigangatho emininzi ebalulekileyo yamazwe ngamazwe kunye nelizwe, iqinisekisa ukuthembeka kwayo kunye nomgangatho. Umzekelo:

• I-ASME B16.11:Ichaza ukusetyenziswa kwayo ekwenziweni kwe-socket weld kunye nezifakelo zemibhobho enemisonto.

• I-ASTM A240/A240M:Ibonelela ngezikhokelo zeepleyiti zensimbi ezingenasici ezisetyenziswa kwizicelo ezahlukeneyo.

• EN 10088-2:Iinkcukacha ngeemfuno zeemveliso zensimbi engenasici eYurophu.

Oku kubambelela kwimigangatho engqongqo kuqinisekisa ukuba i-S31803 ihlangabezana neemfuno zezicelo ezibalulekileyo kwihlabathi jikelele.

Ukuqukumbela

I-S31803 i-duplex steel stainless igqamile njengesixhobo esiguquguqukayo kunye nesomeleleyo esilungele iimeko zemizi-mveliso. Ukudityaniswa kwayo okugqwesileyo kwamandla aphezulu, ukumelana nokugqwesa okuphezulu, kunye nokuthenjwa kwe-weldability kuyenza ibe lolona khetho luphezulu kuwo onke amacandelo afana nokusetyenzwa kweekhemikhali, i-oyile kunye negesi, ubunjineli baselwandle, imveliso yamandla kunye nokwakha. Njengoko amashishini aqhubeka nokutyhala imida yokusebenza kunye nokuqina, i-S31803 ihlala iyinto ekhethwayo enikezela ngexabiso elihlala lihleli kunye nokhuseleko.

Ukufumana iinkcukacha ezithe kratya zobugcisa kunye nezisombululo ezilungiselelweyo, iingcali zeshishini ziyakhuthazwa ukuba zijongane nedatha yedatha kwaye uqhagamshelane nabanikezeli abathembekileyo.
