First Hastelloy B3 fasteners provide excellent resistance to hydrochloric acid at all concentrations and temperatures up to the 40C, but like zirconium, experiences corrosion failure in the presence of oxidizers. The Hastelloy family of alloys are very well suitedto handle HCl at various temperatures and concentrations, yet some grades perform better than others in HCl. There are few environments more corrosive than hydrochloric acid. Zirconium fasteners are second best, exhibiting a corrosion rate of less than 5mpy at all concentrations and temperatures of HCl below the boiling point. {:^4[_`J>L"0"*O0AIpb+GoPm@Ll+P9Z 2 0 obj
