STRESS CORROSION SUSCEPTIBILITY OF HIGHWAY BRIDGE CONSTRUCTION STEELS-PHASE IIB
Eleven steels typically used in highway bridge construction were evaluated for stress corrosion resistance in various environments. The effects of welding and 5% cold work were also investigated. Laboratory tests were verified by exposure of specimens at selected locations inteh United States. Both ASTM A325 and ASTM A490 bolts were evaluated for stress corrosion resistance in similar environments. The effects of hot dip galvanizing and mechanical galvanizing on the stress corrosion susceptibility were also determined. Tests were performed in tension. Suspension cable and prestressing wires were evaluated for stress corrosion resistance. The suspension cable wires were tested with no coating, and with hot dip galvanized and electrogalvanized coatings. Tests were performed in tension. Corrosion products from the CarquinezStraits bridge were analyzed for chemical composition. /Author/
