PERFORMANCE OF HIGH-STRENGTH BOLTS

HYDROGEN-STRESS CRACKING AND STRESS-CORROSION CRACKING ARE TWO MECHANISMS WHICH HAVE BEEN RESPONSIBLE FOR MANY PREMATURE FAILURES IN HIGH-STRENGTH-STEEL STRUCTURAL MEMBERS. BOTH THE STRENGTH LEVEL AND THE MAGNITUDE OF THE STRESS ARE IMPORTANT FACTORS IN BOTH FRACTURE MECHANISMS. GALVANIZED A-490 BOLTS HEAT TREATED TO WITHIN SPECIFICATION STRENGTH LEVEL DID EXHIBIT SOME SUSCEPTIBILITY TO STRESS CORROSION CRACKING IN BOTH LABORATORY AND NATURAL ENVIRONMENTS. BLACK A-490 BOLTS, ON THE OTHER HAND, CAN BE PROPERLY FABRICATED TO ELIMINATE PROBLEMS FROM HYDROGEN STRESS CRACKING AND STRESS-CORROSION CRACKING.
