ASTM A576 Properties⚙️ (Chem., Mech. & Rankings) rev. 2022

In this post I'll talk about and give details about ASTM A576. First let's describe it and then have a look at its material's properties.

What is ASTM A576?

ASTM A576 is a Specification for Steel Bars, Carbon, Hot-Wrought, Special Quality

Category

Steel Bars

Scope

This specification covers hot-wrought special quality carbon steel bars. Special quality bar applications include forging, heat treating, cold drawing, machining, and many structural uses.

Ok let's start with ASTM A576 chemical composition.

Chemical Composition

Grade 1045

C

0.43 - 0.50

Mn

0.60 - 0.90

P max.

0.040

S max.

0.050

Now it's the mechanical properties turn:

Yield Strength

Not required

Learn more about what is yield strength.

Tensile Strength

Not required

Learn more about what is tensile strength.

Elongation (min.)

Not Required.

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 A576 currently ranks 160 in my yield strength index. This means there are other 159 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.

References

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 A576 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.
