Titanium vs. Hastelloy Hose Clamps?
Titanium Grade 2 hose clamps are fully resistant to chlorides, hypochlorites, chlorates, perchlorates and chlorine dioxide. They are ideal for sea water corrosion such as marine vessels and offshore oil, bleaching and chloride environments and salt water applications such as desalination. Hastelloy C276 hose clamps are used in the harshest chemical environments where there is exposure to highly corrosive media like sulfuric and hydrochloric acid.
