They also mention on page 1-71 that "Structural tubing is available conforming to the physical and chemical properties of either ASTM A7 or A36 steel."
There is no mention of any grades of tubing at this point in time that I can see.
In the tube column tables on pages 3-48 through 3-56, they are all lisated as Fy = 36 ksi material.

Looking ahead to the 7th Edition (1970), the tube columns are called out as both Fy = 36 and Fy + 46 KSI material on paGES 3-41 through 3-56. Page 3-37 identifies the 36 ksi material as ASTM A501, and the 46 ksi material as A500 Grade B.
Kinda looks like you might be in the timeline of change and need an assay to determine the exact animal you have.

In thinking further, the material you have is more than likely A-36 from what I can see here, considering the early to mid 60's timeframe.
The 6th AISC edition first came out in 1963, but the copy I have is from a 1967 copyright subsequent printing.
