316L Insimbi Engagqwali

Ukwakheka, Izimpawu Nezicelo

Ukuze uqonde insimbi engagqwali engu-316L, umuntu kufanele aqale aqonde insimbi engagqwali engu-316.

I-316 iyinsimbi engenasici ye-chromium-nickel ephakathi kokubili no-3% kwe-molybdenum.Okuqukethwe kwe-molybdenum kuthuthukisa ukumelana nokugqwala, kukhulisa ukumelana nokugoba izixazululo ze-ion ye-chloride, futhi kuthuthukisa amandla emazingeni okushisa aphezulu.

Iyini i-316L Stainless Steel?

I-316L iyizinga le-carbon ephansi lika-316. Leli banga alivikelekile ekuzwelweni (imvula ye-grain boundary carbide).Isetshenziswa njalo ezingxenyeni ezishiselwe igeji elisindayo (cishe ngaphezu kuka-6mm).Awukho umehluko wentengo ophawulekayo phakathi kuka-316 no-316L wensimbi engagqwali.

Insimbi engagqwali engu-316L inikeza ukukhasa okuphezulu, ingcindezi ekuqhekekeni namandla aqinile emazingeni okushisa aphakeme kunezinsimbi ezingenasici ze-chromium-nickel austenitic.

Izimpawu ze-alloy

Igama elithi “L” limane lisho “ikhabhoni encane.”I-316L iqukethe ikhabhoni encane kune-316.

Izimpawu ezivamile yi-L, F, N, kanye no-H. Isakhiwo se-austenitic salawa mabanga sinikeza ukuqina okuhle kakhulu, ngisho nasemazingeni okushisa e-cryogenic.

304 vs. 316 Insimbi Engagqwali

Ngokungafani nensimbi engu-304 - insimbi engagqwali ethandwa kakhulu - i-316 inokumelana okuthuthukisiwe kokugqwala okuvela ku-chloride namanye ama-asidi.Lokhu kukwenza kube usizo ezinhlelweni zangaphandle ezindaweni zasolwandle noma izinhlelo zokusebenza ezingabeka engcupheni ukuchayeka ku-chloride.

Kokubili okungu-316 no-316L kubonisa ukumelana nokugqwala okungcono namandla emazingeni okushisa aphakeme kunozakwabo ongu-304 - ikakhulukazi uma kukhulunywa ngokugqwala kwemigodi nokuqhekeka ezindaweni ze-chloride.

316 vs. 316L Insimbi Engagqwali

Insimbi engagqwali engu-316 iqukethe ikhabhoni engaphezulu kuka-316L.Insimbi engagqwali engu-316 inezinga eliphakathi nebanga lekhabhoni futhi iqukethe phakathi kuka-2% no-3% we-molybdenum, enikeza ukumelana nokugqwala, izakhi ezine-asidi, namazinga okushisa aphezulu.

Ukuze ufaneleke njengensimbi engagqwali engu-316L, inani lekhabhoni kufanele libe phansi - ikakhulukazi, alikwazi ukudlula i-0.03%.Amazinga ekhabhoni aphansi aholela ekutheni u-316L athambe kuno-316.

Ngaphandle komehluko wokuqukethwe kwekhabhoni, i-316L ifana kakhulu ne-316 cishe ngazo zonke izindlela.

Zombili izinsimbi ezingenasici zithambile kakhulu, ziwusizo lapho kwakhiwa izimo ezidingekayo zanoma iyiphi iphrojekthi ngaphandle kokuphuka noma nokuqhekeka, futhi zinokumelana okuphezulu nokugqwala kanye namandla aqinile aqinile.

Izindleko phakathi kwalezi zinhlobo ezimbili ziyaqhathaniswa.Kokubili kunikeza ukuqina okuhle, ukumelana nokugqwala, futhi kuyizinketho ezinhle ezinhlelweni zokucindezela okuphezulu.

I-316L ithathwa njengelungele iphrojekthi edinga ukushiselwa okukhulu.I-316, ngakolunye uhlangothi, ayikwazi ukumelana nokugqwala ngaphakathi kwe-weld (ukubola kwe-weld) kuno-316L.Sekushiwo lokho, ukufaka i-316 kuyindlela yokusebenza yokumelana nokubola kwe-weld.

I-316L ilungele izinga lokushisa eliphezulu, ukusetshenziswa kokugqwala okuphezulu, okuhambisana nokuduma kwayo kumaphrojekthi wokwakha nasolwandle.

Kokubili i-316 kanye ne-316L inokusebenziseka okuhle kakhulu, kusebenza kahle ekugobeni, ukwelula, ukudweba okujulile, nokuphotha.Kodwa-ke, i-316 iyinsimbi eqinile kakhulu enamandla amakhulu okudonsa kanye ne-ductility uma iqhathaniswa ne-316L.
