Bethlehem Steel proposed to SP-7 to conduct a study to evaluate the benefits of new higher strength low alloy HSLA steels. In Phases I and II, we would determine the ability of the new HSLA steels to withstand high welding heat inputs, without using sustained preheat, and have only limited heat zone degradation. Yield points to be attained were 80 ksi through 3 inches thick 75 ksi through 5 inches thick and 70 ksi through 8 inches thick. The HSLA to be used was ASTM A710, Grade A, Class 3.
