EVALUATION OF REGULAR STRENGTH AND HIGH STRENGTH STEEL WIRES FOR NOTCH FRACTURE OUGHNESS AND STRESS CORROSION PROPERTIES
■ A project was initiated to evaluate the 0.1493” and 0.136” diameter low strength and high strength steel wires for notch fracture toughness and stress corrosion tests. Steel wire samples received from Southwire Co. were tagged as follow;
■ Special 0.1493” diameter, 275ksi UTS
■ Regular 0.1493” diameter, 220ksi UTS
■ Special 0.136” diameter, 285ksi UTS
■ Regular 0.136” diameter, 225ksi UTS
■ Currently, Southwire is using “regular 0.1493” diameter and 0.136” diameter” wires in their aluminum conductors. Recently, Southwire has developed a special wire which has higher UTS and YTS than the regular strength wire for use in aluminum conductors to increase the overall strength of the conductors. It is important to know the fracture toughness and stress corrosion properties of the high strength steel core wires since the conductors will be exposed to outside environments.
