ASTM A653 Properties (Chem., Mech. & Rankings)

In this post I'll talk about and give details about ASTM A653. First let's describe it and then have a look at its material's properties.

What is ASTM A653?

ASTM A653 is a Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy- Coated (Galvannealed) by the Hot-Dip Process


Steel Sheet,


This specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot dip process in coils and cut lengths.

Ok let's start with ASTM A653 chemical composition.

Chemical Composition

Grade CS Type B


0.02 - 0.15

Mn max.


P max.


S max.


Cu max.


Ni max.


Cr max.


Mo max.


V max.


Nb max.


Ti max.

Now it's the mechanical properties turn:

Yield Strength

Grade CS Type B (Non mandatory)

30 - 55 ksi (205 - 380 MPa)

Learn more about what is yield strength.

Elongation (min.) 50 mm


Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.


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 A653 currently ranks 124 in my yield strength index. This means there are other 123 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.

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 A653 Properties (Chem., Mech. & Rankings). Materials Blog. 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.
