Incazelo emfushane:

Amashubhu Ensimbi Engagqwali ye-UNS S31254. I-UNS S31254 iyinsimbi engagqwali ye-super austenitic enezinga eliphezulu le-molybdenum ne-nitrogen, enikeza ukumelana okuphezulu kokugqwala kwemigodi kanye nokugqwala kwemigodi kanye namandla aphezulu uma kuqhathaniswa nezinsimbi ezivamile ze-austenitic ezifana ne-316L. I-UNS S31254 iyizinga le-austenitic lapho ukwengezwa kwe-chromium, i-molybdenum ne-nitrogen kunikeza ukumelana okuphezulu kokugqwala emanzini olwandle. Le alloy ine-average Pitting Resistance Equivalent Number (‚PREN' = Cr+3.3Mo+16N) engu-43.8. Ukuhlolwa kubonisa ukumelana okuphezulu ekuhlaselweni kokugqwala kwemigodi emanzini olwandle kanye nokucindezela ukuqhekeka kokugqwala emanzini olwandle kanye ne-sodium chloride eshisayo egxilile. Uma kuqhathaniswa nezinsimbi ze-CrNiMo 17 12 2.5, ikhombisa ukumelana okuphezulu kokugqwala kuma-acid amaningi ngamanani afanayo futhi amandla ayo okukhiqiza aphakeme cishe ngo-50%. Ukushintshwa okuhle kusetshenziswa izinto ezidliwayo ze-Ni-Cr-Mo. Ukucisha ugesi kanye nezikhathi ezimfushane ngaphakathi kobubanzi buka-600-1000°C kugwema ukuthuthukiswa okungenzeka kwesigaba se-sigma esiyingozi, esingase sibhidlize futhi siphazamise ukumelana nokugqwala.
