请问哈氏合金问题？ 不清楚你的具体工况，存在氧化性气体、及其它的杂质？下面的一段话希望对你有借鉴—— the most corrosion resistant of the nickel-base alloys to hydrochloric acid are hastelloy b-2 (ni-28mo) and hastelloy c-276 (ni-i6cr15.5mo). hastelloyb-2 is one of the few metals with a corrosionrate under 0.5 mmlyr(20 rnils/yr) in all concentrations and at temperatures up to the atmospheric boiling point in nonaerated acidin the absence of oxidizing agents. hastelloyc-276has excellent corrosion resistance«0.13 mmlyr, or 5 mils/yr) in all concentrations of hydrochlori cacid at room temperatures and good resistance «0.5 mmlyr,or 20milslyr) to all concentrations up to 50°c (120 of). at concentrations under 10%,its resistance often exceeds that of hastelloy b-2. oxygen and strong oxidizing agent accelerate corrosion, although markedly less than for hastelloyb-2. 查看更多
