In the -20 revision of A615, the minimum tensile strengths for A615 grades 60 (420) and 80 (550) were adjusted to match the minimum requirements of A706. This eliminated the technical need to have both the W and S on the bar to indicate dual grade material. Going forward, all bar that meets A706 also meets A615, 100% of the time. Therefore, the W alone is sufficient to indicate conformance to both A615 and A706.
