Answer
MP35N (nikel-cobalt base alloy) ni igipimo cya zahabu kumasoko y'amazi yo mu nyanja kubera ubudahangarwa bwa Hydrogen Induced Stress Cracking (HISC) na Sulfide Stress Cracking (SSC) mubidukikije 'bikarishye' birimo $ H_2S $. MP35N igera ku mbaraga zidasanzwe (kugeza $ 300 $ ksi) binyuze mu gukora gukomera no gusaza. Bitandukanye na 17-7PH, ishobora kuba ishobora kwinjizwa mu bihe bimwe na bimwe bya electrolytike yo mu nyanja, MP35N ikomeza guhindagurika no kurwanya umunaniro. Amavuta menshi ya Modulus ya Elastique ($ 33.8 \ inshuro 10 ^ 6 $ psi) yemerera ibiciro byimpeshyi cyane mumabahasha yuzuye. Kubikoresho byo mumazi yo munsi yinyanja hamwe nubuzima bwimyaka 25 yubuzima bwa serivisi, kuba ibikoresho birwanya SCC iterwa na chloride hamwe nubwinshi bwayo bwo kurinda catodiki bituma ihitamo ryonyine nubwo igiciro cyayo gikabije.
