I-akhawunti ye-Duplex stainless ye-Steress ye- Kuthuthukiswe ngawo-1930 ukuthola uhlelo lokusebenza ephepheni nasePulp e-Alloys, ama-Alloys e-Duplex asuselwa ekwakhekeni okungu-22% CR kanye ne-auntenitic exubile
Uma kuqhathaniswa nama-generic 304/316 auntenitic ama-autenitic steanless acreinless, umndeni wakwaDuplex amabanga azoba namandla kabili futhi anikeze ukuphakama okukhulu ekuphikisweni kokugqwala. Ukwandisa okuqukethwe kwe-chromium kwama-steres angenasici kuzokwandisa ukumelana kwabo ngokuqina. Kodwa-ke, inani elilinganayo lokuphikiswa (pren) elifaka ukumelana kwama-alloys ekugqwaneni okukhonkotha kuhlanganisa nezinye izinto eziningi kwifomula yayo. Lokhu kubukisa kungasetjenziselwa ukuchaza ukuthi umehluko phakathi kwe-UNS S3180003 futhi uns S32205 wakhula nokuthi uyaphila yini.
Ngemuva kwentuthuko yensimbi engagqwali, ukucaciswa kwawo kokuqala kwathunjwa njengo-Ex S31803. Kodwa-ke, inqwaba yabakhiqizi abaholayo bakhiqiza njalo leli banga kuze kube sekupheleni okuphezulu kokucaciswa okuvumelekile. Lokhu kubonise isifiso sabo sokwandisa ukusebenza kokugqwala kwe-alloy, kusizwa ukuthuthukiswa kwenqubo ye-aod yensimbi evumela ukulawulwa okunzima kokwakheka. Ngaphezu kwalokho, kubuye kwavumela izinga lokungezwa kwe-nitrogen ukuthi lithonywe, kunokuba livezwe njengento yangemuva. Ngakho-ke, ibanga eliphakeme kakhulu le-Dumplex lifuna ukukhulisa amazinga we-chromium (CR), i-molybdenum (Mo) ne-nitrogen (n). Umehluko phakathi kwe-Dumplex AllOY Ukwakheka kwawo okuhambisana nokwakheka, okuqhathaniswa okukodwa okucashile okucacisiwe kungaba ngamaphuzu ambalwa asuselwa kufomula Pren =% CR + 3.3 NO
Ukuze uhlukanise insimbi engenacala ekhiqizwe ekugcineni kwebanga lokuhlanganiswa, kwaqalwa okunye ukucaciswa, okungukuthi us S32205. Insimbi engagqwali eyenziwe nge-S32205 (F60) ncazo izohlangana ngokuphelele ne-S31803 (F51) ncazo, kanti ukuphindisela akulona iqiniso. Ngakho-ke i-S32205 ingaqinisekiswa kabili njenge-S31803.

SakySteel stock uhlu oluphelele lwensimbi engenacala njengomlingani owuthandayo wokusatshalaliswa kweSandvik. Sifaka ama-s32205 ngosayizi kusuka ku-5/8 "ububanzi ku-bar eyindilinga, enabaningi besitoko sethu esitokisini seSANMac® 2205 ebangeni, okunezela 'umsebenzi othuthukisiwe njengezinto ezijwayelekile. Ngaphezu kwalokho, siphinde sigcine uhla lwe-S32205 Hollow Bar kusuka e-Warehouse yethu yase-UK, nepuleti kuze kufike ku-3 "kusuka ePortland yethu, e-USA Warehouse.
