317L Chitsulo chosapanga dzimbiri UNS S31703

Mafomu a 317L Stainless Steel Akupezeka ku Cepheus Stainless Steel

• Mapepala
• Mbale
• Malo
• Chitoliro & Tube (zowotcherera & zopanda msoko)
• Zopangira (ie ma flanges, ma slip-ons, blinds, weld-necks, lapjoints, weld makosi aatali, socket welds, elbows, tees, stub-ends, returns, zisoti, mitanda, zochepetsera, ndi nsonga zamapaipi)
• Weld Waya (AWS E317L-16, ER317L)

317L Chitsulo Chosapanga dzimbiri

317L ndi mtundu wa molybdenum wokhala ndi "L" wokhala ndi mpweya wochepachitsulo chosapanga dzimbiri cha austeniticzomwe zimapereka kukana kwa dzimbiri bwino pa 304L ndi 316L zitsulo zosapanga dzimbiri. Mpweya wochepa umapereka kukana kukhudzidwa panthawi yowotcherera ndi njira zina zotentha.

317L ndi yopanda maginito yomwe ili mu annealed koma imatha kukhala maginito pang'ono chifukwa cha kuwotcherera.

Kukaniza kwa Corrosion

317L ili ndi kukana kwambiri kwa dzimbiri mumitundu yosiyanasiyana yamankhwala, makamaka m'malo a acidic chloride monga omwe amakumana nawo muzamkati ndi mphero zamapepala. Kuchulukitsa kwa chromium, faifi tambala ndi molybdenum poyerekeza ndi 316L chitsulo chosapanga dzimbiri kumathandizira kukana kuyika kwa chloride ndi dzimbiri wamba. Kukana kumawonjezeka ndi molybdenum alloy content. 317L imalimbana ndi kuchuluka kwa sulfuric acid mpaka 5 peresenti pa kutentha kwambiri mpaka 120 ° F (49 ° C). Pakutentha pansi pa 100 ° F (38 ° C) aloyiyi imakhala ndi kukana kwambiri zothetsera ndende zapamwamba. Komabe, kuyesa kwautumiki kumalimbikitsidwa kuti afotokozere zomwe zingakhudze magwiridwe antchito omwe angakhudze machitidwe a dzimbiri. M'njira zomwe kutsekemera kwa mpweya wokhala ndi sulfure kumachitika, 317L imakhala yolimba kwambiri kuti iwonongeke pamtunda wa condensation kusiyana ndi alloy wamba 316. Kuchuluka kwa asidi kumakhala ndi chikoka pamlingo wa kuukira m'madera oterowo ndipo kuyenera kutsimikiziridwa mosamala ndi ntchito. mayeso.

Kuwotcherera 317L

317L imawotcherera mosavuta ndi njira zambiri zowotcherera (kupatula oxyacetylene). AWS E317L/ER317L zitsulo zodzaza ndi zitsulo kapena austenitic, zitsulo zotsika kaboni zodzaza ndi molybdenum zokwera kuposa 317L, kapena chitsulo cha nickel-base filler chokhala ndi chromium ndi molybdenum yokwanira kupitilira kukana kwa dzimbiri kwa 317L ziyenera kugwiritsidwa ntchito kuwotcherera chitsulo 317L.
