317/317L insimbi engagqwali 6.35 * 0.70mm ishubhu ehlanganisiwe / ishubhu eqondile

Okuqukethwe kwe-molybdenum okuphezulu kwe-Alloy 317L kuqinisekisa ukumelana nokugqwala okujwayelekile okujwayelekile nokwasendaweni emithonjeni eminingi yezindaba uma kuqhathaniswa nezinsimbi ezingenasici ezingu-304/304L nezingu-316/316L.Izindawo ezingahlaseli insimbi engagqwali engu-304/304L ngokuvamile ngeke zigceme u-317L.Okuhlukile, nokho, ama-acids oxidizing kakhulu njenge-nitric acid.Ama-alloys aqukethe i-molybdenum ngokuvamile awasebenzi kahle kulezi zindawo.

I-alloy 317L inokumelana okuhle kakhulu nokugqwala ezinhlobonhlobo zamakhemikhali.Imelana nokuhlaselwa kwe-sulfuric acid, i-acidic chlorine ne-phosphoric acid.Isetshenziselwa ukuphatha ama-acids ashisayo e-organic kanye nama-fatty ngokuvamile akhona ekudleni nasekusetshenzisweni kokucubungula imithi.

Ukumelana nokugqwala kwe-317 kanye ne-317L kufanele kufane kunoma iyiphi indawo enikeziwe.Okuhlukile kulapho ingxubevange izochayeka khona emazingeni okushisa ebangeni lemvula ye-chromium carbide engu-800 – 1500°F (427 – 816°C).Ngenxa yokuqukethwe kwayo kwekhabhoni ephansi, i-317L iyinto ekhethwayo kule sevisi ukuze ivikele ukugqwala kwe-intergranular.

Ngokuvamile, izinsimbi ezingenasici ze-austenitic zingaphansi kwe-chloride stress corrosion cracking enkonzweni ye-halide.Nakuba i-317L ithikameze kakhulu ekuqhekekeni kokugqwala kwengcindezi kunezinsimbi ezingenasici ezingu-304/304L, ngenxa yokuqukethwe kwayo okuphezulu kwe-molybdenum, isengathinteka kalula.

Okuqukethwe okuphezulu kwe-chromium, i-molybdenum ne-nitrogen okungu-317L kuthuthukisa ikhono layo lokumelana nokugqwala nokugqwala lapho kukhona ama-chloride namanye ama-halide.I-Pitting Resistance Equivalent kuhlanganise nenombolo yeNitrojeni (PREN) isilinganiso esihlobene sokumelana nokugoba.Ishadi elilandelayo linikeza i-Alloy 317L yokuqhathanisa nezinye izinsimbi ezingenasici ze-austenitic.
