Hastelloy B: The Corrosion-Resistant Vanguard insait long Reductive Corrosive Environments
Dec 23, 2025
Olsem wanpela 'nickel-molybdenum-based corrosion-resistant alloy, Hastelloy B i kamap wanpela bikpela samting insait long ol indastri olsem kemikel enjiniaring na petrolium bilong lukautim ol ples we i gat planti korosen, tenkyu long gutpela wok bilong en long 'reductive acid media'. Ol gutpela samting bilong en i stap ples klia tru taim yumi skelim wantaim ol wankain 'alloy'.
Long ol ples we i gat 'reductive acid' olsem 'hydrochloric acid' na 'dilute salfuric acid', 'corrosion resistance' bilong Hastelloy B em i wanpela "benchmark." I no olsem 316L steinles stiel, we i save kisim bagarap long hariap korosen insait long medium-konsentresen haidroklorik asid, Hastelloy B i ken wok gut insait long haidroklorik asid long tempereja aninit long 80 digri. Taim yumi skelim wantaim ol 'nickel-chromium alloys (olsem, Inconel 600) we i lukluk long 'oxidation resistance', bikpela 'molybdenum' insait long en (26%-30%) i kamapim wanpela gutpela 'passive layer', we i save sakim gut 'hydrogen ion erosion' na stretim hevi bilong 'passive film degradation' insait long ol 'reductive acids' we ol 'latter' i save bungim.
Hastelloy B i save wok gut tu long ol ples we i gat planti 'chloride ion'. Em i save sakim ol 'pitting', 'crevice corrosion', na 'stress cracking'. Taim yumi skelim wantaim ol 'titanium alloys', we i save kisim 'hydrogen embrittlement' insait long 'reductive hydrochloric acid', o ol 'Monel alloys', we i no gat inap 'corrosion resistance' insait long bikpela 'tempereture', 'high-concentration hydrochloric acid, Hastelloy B i save givim gutpela longpela taim. Maski long bikpela -temperature (200-300 digri ) reduktiv asid o salfa-i gat ol midia-olsem ol hatpela kondisen bilong ol petrolium haidrodesulfuraisesen yunit-em i save holim gutpela mekanikel samting na korosen resistens, na i no save bagarap longpela taim ol ain na sampela nikel-kromiam-ain aloi.
Ol gutpela samting bilong en antap long ol narapela Hastelloy gred i bikpela samting: insait long pure reductive hydrochloric acid, em i soim gutpela korosen resistans winim Hastelloy C series (we i gutpela long miks midia) long liklik pe; insait long bikpela -konsentresen bilong 'hydrochloric acid', strong bilong en long sakim korosen i winim bilong Hastelloy G series, we i lukluk long 'sulfuric acid resistance'.
Stat long ol leboretori i go inap long ol indastrial sait, Hastelloy B, wantaim ol gutpela samting bilong en we i no inap bagarap, i wok long kamap olsem wanpela "protektiv banis" insait long ol ples we i no gat planti bagarap.
