Inkcazo emfutshane:

Iityhubhu ze-UNS S31254 zeNtsimbi Engagqwaliyo. I-UNS S31254 yintsimbi engagqwaliyo e-super austenitic enezinga eliphezulu le-molybdenum kunye ne-nitrogen, enika ukumelana okuphezulu kokugqwala kwemingxuma kunye nokugqwala kwemingxuma kunye namandla aphezulu xa kuthelekiswa neentsimbi ze-austenitic ezixhaphakileyo ezifana ne-316L. I-UNS S31254 yinqanaba le-austenitic apho ukongezwa kwe-chromium, i-molybdenum kunye ne-nitrogen kunika ukumelana okuphezulu kokugqwala emanzini olwandle. Le alloy ine-avareji ye-Pitting Resistance Equivalent Number (‚PREN' = Cr+3.3Mo+16N) ye-43.8. Uvavanyo lubonisa ukumelana okuphezulu kokugqwala kwemingxuma emanzini olwandle kunye nokuqhekeka kokugqwala kwi-sodium chloride eshushu. Xa kuthelekiswa neentsimbi ze-CrNiMo 17 12 2.5, ibonisa ukumelana okuphezulu kokugqwala kwii-acids ezininzi kumanqanaba afanayo kwaye amandla ayo okuvelisa aphezulu malunga ne-50%. Ukudityaniswa okuhle kusetyenziswa izinto ezisetyenziswayo ze-Ni-Cr-Mo. Ukucinywa komlilo kunye nexesha elifutshane ngaphakathi koluhlu lwe-600-1000°C kuthintela uphuhliso olunokwenzeka lwesigaba se-sigma esibi, esinokuqhekeza kwaye sithintele ukuxhathisa ukugqwala.
