What is ASTM A82?ASTM A82 is a Specification for Steel Wire, Plain, for Concrete Reinforcement
ScopeThis specification covers cold-drawn steel wire, as drawn or galvanized, to be used as such, or in fabricated form, for the reinforcement of concrete, in sizes not less than 2.03 mm (0.080 in.) nominal diameter.
Ok let's start with ASTM A82 chemical composition.
The steel shall be made by one of the following processes: open-hearth, electric furnace, or basic-oxygen.
Learn more about chemical composition.
Now it's the mechanical properties turn:
70 ksi (485 MPa) min.
Learn more about what is yield strength.
80 ksi (550 MPa) min.
Learn more about what is tensile strength.
Reduction of Area (min. %)0.3.
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 A82 currently ranks 28 in my yield strength index. This means there are other 27 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 A82 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.
