2205 Duplex Overview
I-Duplex 2205 yinitrogen eyongeziweyointsimbi ephindwe kabinieyaphuhliswa ukulwa iingxaki zomhlwa eziqhelekileyo ezidibene ne-300 series steels stainless."I-Duplex" ichaza usapho lweentsimbi ezingenasici ezingenasici ngokupheleleyo, njenge-304 engenasici, okanye i-ferritic ecocekileyo, njenge-430 engenasici.Isakhiwo se-2205 duplex insimbi engenasici iqukethe amachibi e-austenite ajikelezwe yinqanaba eliqhubekayo le-ferrite.Kwimeko ye-annealed, i-2205 iqulethe malunga ne-40-50% ye-ferrite.Idla ngokubizwa ngokuba libakala lehashe lomsebenzi, i-2205 lelona bakala lisetyenziswa kakhulu kusapho lwe-duplex yeentsimbi ezingenasici.

Ukusetyenziswa kwe-2205 Duplex steel stainless kufuneka kukhawulelwe kumaqondo obushushu angaphantsi kwe-600 ° F. Ukwandiswa kweqondo lobushushu eliphakamileyo linokukhupha i-2205 engenasici.

Ukunyangwa kokuMhlwa
I-2205 i-duplex steel stainless sisisombululo esinexabiso elisebenzayo kwizicelo ezininzi apho i-300 series steels stainless steels ichaphazeleka kwi-chloride stress corrosion cracking.Uxinzelelo lwe-corrosion cracking lwenzeka xa iintsimbi ezingenastainless ziphantsi koxinzelelo lwe-tensile, ngelixa zidibana nezisombululo ezinekloridi.Ukunyuka kwamaqondo obushushu kukwanyusa ukuchaphazeleka kweentsimbi ezingenasici ukuxinzelela ukuqhekeka komhlwa.
Indibaniselwano yechromium, imolybdenum kunye nenitrogen idlulisa ukuxhathisa okulungileyo kwe-2205 kwimingxuma yekloridi kunye nokuhlwa kwemingxuma.Oku kuxhathisa kubaluleke kakhulu kwiinkonzo ezinje ngemekobume yaselwandle, amanzi anebraksh, ukusebenza kwebleaching, iinkqubo zamanzi ezivaliweyo kunye nezinye izicelo zokulungisa ukutya.I-chromium ephezulu, i-molybdenum kunye ne-nitrogen iziqulatho ze-2205 zibonelela ngokumelana nokugqwala okungaphezulu kweentsimbi eziqhelekileyo ezingenasici, ezifana ne-316L kunye ne-317L kwiindawo ezininzi.
