Uncoated High-Strength Steel Bars for Prestressing Concrete (ASTM A 722).13 Nearly all strand used in precast, prestressed concrete products is seven-wire strand conforming with ASTM A416, manufactured with low-relaxation wire conforming with the supplement to ASTM A421. Other prestressing steel that is occasionally used includes three-wire 150 KSI ALL THREAD BAR - jennmar.aupliance with ASTM A722-07 and AASHTO M275 Highway Specifications. The prestresslng steel is high in strength yet ductile enough to exceed the specified elon- gation and reduction of area requ rements. Selected heats can also pass the 1350 supplemental bend test when required. Testing has shown Wil iams 150 KSI All- Thread-Bars to meet or exceed post tensioning bar and

ASTM A615 grade 40 ordinary deformedsteel reinforcing bars with a specified minimum yield strength of 276 MPa (40 ksi) and ASTM A722 highstrength prestressing thread bars with a specified ultimate strength of 1,083 MPa (157 ksi) were experimentally evaluated for their lowcycle fatigue behavior under axialstraincontrolled reversed cyclic tests with strain amplitudes ranging from Post-Tensioning System and Prestressing Steel Barsbar strength. Williams 150 KSI bars are manufactured in strict com-pliance with ASTM A722 and AASHTO M275 Highway Specifications. The prestressing steel is high in strength yet ductile enough to exceed the specified elongation and reduction of area requirements. Selected heats can also pass the 135° supplemental bend test when required.
