What is ASTM A996?ASTM A996 is a Specification for Rail-Steel and Axle-Steel Deformed Bars for Concrete Reinforcement
ScopeThis specification covers rail-steel and axle-steel bars for concrete reinforcement. Three types of product are included, designated with a rail symbol, and an R for bars made of rail-steel and with an A for bars made of axle-steel.
Ok let's start with ASTM A996 chemical composition.
CThe ranges of carbon shall be determined by the manufacturer as those best suited to meet the mechanical requirements.
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade 6060 ksi (420 MPa) min.
Learn more about what is yield strength.
Grade 6090 ksi (620 MPa) min.
Learn more about what is tensile strength.
Elongation (min.) 200 mm0.12.
Learn more about what is elongation.
Reduction of Area (min. %)Not Required.
Learn more about reduction of area.
Allowable StressDepends on the project (And its factor of safety).
Learn more about the what is allowable stress.
My Material's RankWhile engineers will often look for the cheapest material they can use, I took a different approach to material's selection to help newbie students.
I ranked materials according to their yield strengths and ASTM A996 currently ranks 37 in my yield strength index. This means there are other 36 materials that are more resistant.
Note: I've analysed 134 materials in order to create an yield strength index. Check my astm material's comparison post for more details.

CitationWhen you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.
That gives credibility to your paper and it is sometimes required in higher education.
To make your life (and citation) easier just copy & paste the information below into your assignment or essay:
Luz, Gelson. ASTM A996 Properties (Chem., Mech. & Rankings). Materials Blog. Gelsonluz.com. dd mmmm. yyyy. <URL>
Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
