Influence of temperature on corrosion behavior of zinc in water

Zinc is one of the most important metals used in prevention of corrosion. It offers galvanic protection to steel and other materials and it is resistant to corrosive atmosphere as well as to sea water and tap water influences. Hot dip galvanized steel is most frequently used in building constructions, container manufacture, taps and pipe fittings in domestic and industrial water works. Zinc is resistant to corrosion in water only in a very narrow pH interval (from 6 to 11). The failure of galvanised steel hot water pipes leads to the conclusion that zinc is not always anodic in its relationship to steel.
