ASTM A36 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A36. First let's describe it and then have a look at its material's properties.

What is ASTM A36?

ASTM A36 is a Specification for Carbon Structural Steel.


Structural Steel


This specification covers carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes.

Ok let's start with ASTM A36 chemical composition.

Chemical Composition


C max.


P max.


S max.


Si max


Cu min.

0.20, when copper steel is specified

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

36 ksi (250 MPa) min

Learn more about what is yield strength.

Tensile Strength

58 - 80 ksi (400 - 550 MPa)

Learn more about what is tensile 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 A36 currently ranks 83 in my yield strength index. This means there are other 82 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.

ASTM Classroom

Are you having trouble understanding the basics of ASTM?

What is the difference between Code, Standard & Specification?

This video will walk you through:



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 A36 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.
