317L Ukubuka konke Kwensimbi Engagqwali
I-317L iyizinga le-molybdenum, okuqukethwe kwekhabhoni ephansi "L".insimbi engagqwali ye-austeniticokunikeza ukumelana nokugqwala okuthuthukisiwe ngaphezu kwezinsimbi ezingama-304L nezingu-316L. Ikhabhoni ephansi inikeza ukumelana nokuzwela ngesikhathi sokushisela nezinye izinqubo ezishisayo.
I-317L ayinawo uzibuthe esimweni esifakwe emanzini kodwa ingase ibe kazibuthe kancane ngenxa yokushisela.
Ukumelana Nokugqwala
I-317L inokumelana nokugqwala okuhle kakhulu kumakhemikhali anhlobonhlobo, ikakhulukazi ezindaweni ezine-acidic chloride njengalezo ezitholakala ku-pulp kanye nezigayo zephepha. Amazinga anyusiwe e-chromium, i-nickel ne-molybdenum uma kuqhathaniswa ne-316L yensimbi engagqwali athuthukisa ukumelana ne-chloride pitting kanye nokugqwala okuvamile. Ukumelana kuyanda ngokuqukethwe kwe-molybdenum alloy. I-317L imelana nokugxilwa kwe-sulfuric acid kufika kumaphesenti angu-5 emazingeni okushisa aphezulu njengo-120°F (49°C). Emazingeni okushisa angaphansi kuka-100°F (38°C) le ngxubevange inokumelana okuhle nezixazululo zokugxila okuphezulu. Kodwa-ke, ukuhlolwa kwesevisi kuyanconywa ukuthi kubhekele imithelela yezimo ezithile zokusebenza ezingase zithinte ukuziphatha kokugqwala. Ezinqubweni lapho ukufingqa kwamagesi anesulfure kwenzeka, i-317L imelana kakhulu nokuhlasela endaweni yokuncibilika kune-alloy evamile 316. Ukuhlushwa kwe-asidi kunethonya eliphawulekayo ngezinga lokuhlasela ezindaweni ezinjalo futhi kufanele kunqunywe ngokucophelela ngesevisi. izivivinyo.

Ukushisela 317L
I-317L ishiselwa kalula ngohlu olugcwele lwezinqubo zokushisela ezijwayelekile (ngaphandle kwe-oxyacetylene). I-AWS E317L/ER317L yensimbi yokugcwalisa noma i-austenitic, izinsimbi eziphansi ze-carbon filler ezinokuqukethwe kwe-molybdenum ephakeme kunaleyo engama-317L, noma insimbi yokugcwalisa i-nickel-base enokuqukethwe kwe-chromium nokuqukethwe kwe-molybdenum eyanele ukweqa ukumelana nokugqwala okungu-317L kufanele kusetshenziselwe ukushisela insimbi engu-317L.
