Which of the following metal is highly resistant to crevice corrosion?

Which of the following metal is highly resistant to crevice corrosion? Correct Answer Hastelloy C-276

Hastelloy C-276 is the best crevice corrosion-resistant metal. The composition of Hastelloy C-276 is 15.5%Cr, 54.7%Ni, 15.5%Mo, 3.8%W, and 0.5%Mn. Whereas the other metals depend on oxide film for their corrosion resistance.
