Ityhubhu engenamthungo ye-S32750 yentsimbi engagqwaliyo
Intshayelelo yeMveliso
I-Super Duplex stainless efana ne-S32750, sisakhiwo esixutyiweyo se-austenite kunye ne-ferrite (50/50) esiphucule amandla ngaphezu kwe-ferritic kunye ne-austenitic steel grades. Umahluko ophambili kukuba i-Super Duplex inomxholo ophezulu we-molybdenum kunye ne-chromium onika izinto ezisemgangathweni ophezulu. I-chromium ephezulu ikwakhuthaza ukwakheka kwezigaba ezinobungozi ze-intermetallic, ezibuthathaka kwi-475°C embrittlement ngenxa yokuna kwesigaba se-α' esityebileyo kwi-chromium, kunye nokubhitya yi-sigma, i-chi kunye nezinye izigaba kumaqondo obushushu aphezulu.
I-Alloy 2507 (S32750) ikwanomxholo ophezulu we-nitrogen, engakhuthazi kuphela ukwakheka kwe-austenite kwaye yonyusa amandla, kodwa ikwalibazisa ukwakheka kwezigaba ze-intermetallic ngokwaneleyo ukuvumela ukucutshungulwa kunye nokwenziwa komgangatho we-duplex.
Olu hlobo luphawulwa kukumelana nokugqwala kwe-chloride okuhle kakhulu, kunye namandla aphezulu oomatshini. Lufanelekile ngokukodwa ukusetyenziswa kwiindawo ezinobundlongondlongo ezifana namanzi olwandle afudumeleyo ane-chlorine kunye ne-acidic chloride-containing media.
Iimpawu ze-Alloy 2507 (S32750) zezi zilandelayo:
● Ukumelana kakuhle nokuqhekeka koxinzelelo (SCC) kwiindawo ezine-chloride
● Ukumelana kakuhle nokugqwala kwemingxuma kunye ne-crevice
● Ukumelana okuphezulu nokugqwala ngokubanzi
● Amandla aphezulu kakhulu oomatshini
● Iimpawu ezibonakalayo ezibonelela ngeenzuzo zoyilo
● Ukumelana kakhulu nokugqwala nokudinwa kokugqwala
● Ukudityaniswa kakuhle
I-S32750 yenzelwe ukusetyenziswa okunamandla kakhulu kunye nokumelana nokugqwala, okufumaneka kwiinkqubo yeekhemikhali, izixhobo ze-petrochemical, kunye nezamanzi olwandle. Isetyenziswa kakhulu ekuphononongeni/ekuveliseni ioyile negesi elunxwemeni nakwiindawo zokutshintshiselana ngobushushu kwi-petrochemical/chemical processing. Olu hlobo lukwafanelekile kwiindlela ze-hydraulic kunye nezixhobo kwiindawo zaselwandle ezishushu.
