the high chloride level from the steam. Alternative materials include fiber-reinforced plastic construction, nonmetallic linings, and more corrosion-resistant metals such as titanium and Ni-Cr-Mo alloys such as UNS N10276 and N06625, if the cost can be justified. Corrosion form and mechanism More

... price levels, produces little incentive to change. Historically, in areas where 316L was not adequate, the high-Ni-Cr-Mo alloy C-276 (UNS N10276) was the alternate choice. In the 1970s and 1980s, numerous alloys intermediate to 316L and C-276 were developed that offered the chemical and corrosion...

... of the participants reported any incidence of crevice corrosion for nickel alloy C-276 (UNS N10276), which contains ∼15% Mo. On the other hand, at least one specimen of alloy G (UNS N06007), which contains ∼6% Mo, initiated attack at all eight test locations. Overall, the actual number of crevice sites attacked...

They are similar in composition and corrosion characteristics and may also be useful in contaminated phosphoric acid because of their higher molybdenum content. These alloys also exhibit active/passive behavior near...

... with the material. However, such confidence may be misplaced. For example, there have been a number of accounts in which alloys have been substituted, resulting in premature failure. In one case, this occurred when Hastelloy B (UNS N10001) valves were substituted for the Hastelloy C-276 (UNS N10276) valves...
