What is ASTM A992?ASTM A992 is a Specification for Structural Steel Shapes
CategoryStructural Steel Shapes
ScopeThis specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes.
Ok let's start with ASTM A992 chemical composition.
Mn0.50 - 1.50
Learn more about chemical composition.
Now it's the mechanical properties turn:
50 - 65 ksi (345 - 450 MPa)
Learn more about what is yield strength.
65 ksi (450 MPa) min.
Learn more about what is tensile strength.
Elongation (min.) 200 mm0.18.
Learn more about what is elongation.
Reduction of Area (min. %)Not Required.
Learn more about reduction of area.
Density7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).
Learn more about density.
Elastic Modulus190 GPa (27557 ksi) - 210GPa (30458 ksi).
Learn more about the Elastic Modulus.
Poisson's Ratio0.27 – 0.30.
Learn more about the poisson ratio.
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 A992 currently ranks 52 in my yield strength index. This means there are other 51 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 A992 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.
