ASTM A572 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A572. First let's describe it and then have a look at its material's properties.

What is ASTM A572?

ASTM A572 is a Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel.

Category

Structural Steel

Scope

This 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.

Chemical Composition

C max.

0.21

Mn max.

1.35

P max.

0.04

S max.

0.05

Si max.

0.40

Nb

0.005 - 0.05

V

0.01 - 0.15

Now it's the mechanical properties turn:

Yield Strength

Grade 50

50 ksi ( 345 MPa) min.

Learn more about what is yield strength.

Tensile Strength

Grade 50

65 ksi (450 MPa) min.

Learn more about what is tensile strength.

Elongation (min.) 200 mm

0.18.

Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.

Density

7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).

Learn more about density.

Elastic Modulus

190 GPa (27557 ksi) - 210GPa (30458 ksi).

Learn more about the Elastic Modulus.

Poisson's Ratio

0.27 – 0.30.

Learn more about the poisson ratio.

Allowable Stress

Depends on the project (And its factor of safety).

Learn more about the what is allowable stress.

My Material's Rank

While 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.

Citation

When 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.
