Korrosionsbeständige Werkstoffe für Tanks in gasbetriebenen Fahrzeugen

Corrosion-resistant materials for tanks in gas-driven vehicles Compressed natural gas is increasingly used as drive for internal-combustion engines world-wide. The employed tank material consists of composite pressure tanks made of heat-treated steel or aluminum. Tanks of steel have to be resistant against stress corrosion cracking, tanks of aluminum respectively against intergranular corrosion. This paper describes the necessary acceptance tests.
