ASTM A996 PDF
% Recycled and Equivalent to ASTM A rebar! Made exclusively by Byer Steel, A axle grade rebar is manufactured using train axles as its only raw. Third Party Testing Data shows A rebar performs consistent with ASTM, ASHTO, and ACI Standards making it a more cost effective alternative to A ASTM A is used for testing rail steel and all steel deformed bars used in concrete reinforcement. The specification looks at the standard sizes of deformed bar.

A was withdrawn in I would be concerned since quite a few thing have changed since then. When it was withdrawn, there were two grades, namely 50 ksi and 60 ksi, so you may be looking at a much older version.
As far as A is concerned, is there a reason you are looking at A rail steel instead of A billet steel. A bars are not widely available.

Also, true rail steel bar are not typically fabricated only cut to straight lengthsasfm these bars are not as ductile as other types of reinforcing steel. It is used for fabricating pipe anchors. I have attached the pdf file. Particularly in rail steel, the carbon content is too high for proper welding. While A can be welded, it does require special pre- and post-weld procedures and the associated expense.

Or use another weldable bar stock if deformations are not required. Also, be sure the radius of bend is within the limits for the a969. Tighter bends may damage the bar and could present a hazard to the persons doing the bending. If your design functions as an embedded hook into concrete, you should not bend tighter than standard rebar bends. Where concrete crushing inside the astj is not critical, tighter stirrup bends can be used.
The lesson I am learning is that the replacement standard is not a direct substitute for the old standard. It’s not so much the standard as what we know about the materials, and the evolution of the materials involved. In particular, the nature of rail steel changed as steelmaking changed and as the demands on the rail changed.
Heavier wheel loads, attempts at increased durability, and advances in metallurgy demanded a change in related ASTM specifications. Asttm rebar spec most likely asmt when the kinds of retired rail steel and the processing methods changed. ASTM specs change in response to the supply, not typically because of changes in demand. The dynamic of this is that it is the producers who sit on ASTM committees, because those are the people committed to the work. If structural engineers were more involved in the A CRSI now has a another design engineer liaison to the committee.

As an off-topic example, I am on the newly formed F44 committee on general aviation aircraft, as a pilot and consumer. The organization of the committee and subcommittees will be run by the industry mainly the manufacturers of certified light aircraft which may or may not represent the interests of the consumer very well. This happens because they have the funding and a96 to “control” their sstm. They know what people buy, but what people buy is what is being currently manufactured.
To correlate this to our industry, the industry produces a product and contractors buy the product. When the available scrap supply, or energy prices, or environmental regulations require changes to steel making, the producers will change the ASTM.
The main parameter engineers specify is yield strength, followed by weldability, and then ductility for seismic uses. Producers try to respond to market pressure higher strength, for examplebut there are complications, like ACIwhich limits the use of high strength bars for functional and safety reasons. Without good coordination, there can be a disconnect between supply and demand.
