S32750 Bir aan Xumaan lahayn Tuubooyin

Sharaxaad Gaaban:

Alloy 2507, oo leh lambarka UNS S32750, waa daawaynta laba-waji ah oo ku salaysan nidaamka birta-chromium-nickel oo leh qaab-dhismeed isku dhafan oo qiyaas ahaan siman oo austenite iyo ferrite ah. Sababtoo ah isku dheelitirnaanta wajiga laba-laabka ah, Alloy 2507 waxay soo bandhigaysaa iska caabin heer sare ah oo ku wajahan daxalka guud sida kan birta austenitic ahama ee leh walxo alloying la mid ah. Ka sokow, waxa ay leedahay adkaysi sare iyo xoog dhalid iyo sidoo kale caabbinta chloride SCC si aad ah uga wanaagsan marka loo eego dhiggeeda austenitic iyada oo la ilaalinayo adagaanta ka fiican marka loo eego dhigooda ferritic-ka.

Super Duplex ahama sida S32750, waa qaab-dhismeed isku dhafan oo isku dhafan oo austenite iyo ferrite ah (50/50) kaas oo wanaajiyey awoodda heerarka ferritic iyo austenitic birta. Farqiga ugu weyn ayaa ah in Super Duplex uu leeyahay molybdenum sare iyo chromium ka kooban kaas oo siinaya walxaha chromium ka sarreeya sidoo kale wuxuu kor u qaadaa samaynta wejiyada dhexdhexaadinta waxyeellada leh, kuwaas oo xasaasi u ah 475 ° C embrittlement sababtoo ah roobabka chromium-hodanka ah α'. iyo in lagu dhufto sigma, chi iyo wejiyada kale ee heerkul sare.

Alloy 2507 (S32750) waxa kale oo uu leeyahay content nitrogen sare, taas oo aan kaliya kor u formation of austenite iyo kordhiyaa xoogga, laakiin sidoo kale dib u dhigaysa samaynta weji intermetallic ku filan si ay u oggolaadaan ka baaraandegidda iyo been abuurka ee darajada duplex.

Darajada waxaa lagu gartaa iska caabin daxalka chloride oo aad u wanaagsan, oo ay weheliso xoog farsamo oo aad u sarreeya. Waxay si gaar ah ugu habboon tahay in lagu isticmaalo deegaannada dagaalka badan sida biyaha badda ee diirran ee koloriin leh iyo warbaahinta ka kooban chloride acid.

Alloy 2507 (S32750) sifooyinka waa sida soo socota:

● Iska caabbin heer sare ah oo ka dhan ah dildilaaca daxalka (SCC) ee deegaannada koloriin-qaadka leh
● Iska caabin heersare ah oo u diida daxalka godadka iyo dillaaca
● Iska caabbinta sare ee daxalka guud
● Xoog farsamo oo aad u sarreeya
● Qalabka jirka ee bixiya faa'iidooyinka naqshadeynta
● Iska caabbinta sare ee daxalka iyo daxalka daxalka
● Weldability wanaagsan

S32750 waxaa loogu talagalay dalabaadka codsiyada kuwaas oo u baahan xoog gaar ah iyo iska caabin daxalka, kuwaas oo laga helo gudahahabka kiimikada, petrochemical, iyo qalabka biyaha badda. Waxa si weyn loogu isticmaalaa sahaminta/soosaarka saliidda iyo gaasta xeebaha iyo ku-beddelayaasha kulaylka ee farsamaynta batroolka/kiimikada. Darajadu waxay sidoo kale ku haboon tahay codsiyada hydraulic iyo qalabaynta ee jawiga badda kulaylaha.
