What is ASTM A572?ASTM A572 is a Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel.
ScopeThis specification covers five grades of high strength low-alloy structural steel shapes, plates, sheet piling, and bars.
Ok let's start with ASTM A572 chemical composition.
Nb0.005 - 0.05
V0.01 - 0.15
Learn more about chemical composition.
Now it's the mechanical properties turn:
Grade 5050 ksi ( 345 MPa) min.
Learn more about what is yield strength.
Grade 5065 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 A572 currently ranks 47 in my yield strength index. This means there are other 46 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 A572 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.
