ASTM A434 Properties⚙️ (Chem., Mech. & Rankings) rev. 2022

In this post I'll talk about and give details about ASTM A434. First let's describe it and then have a look at its material's properties.

What is ASTM A434?

ASTM A434 is a Specification for Steel Bars, Alloy, Hot-Wrought or Cold-Finished, Quenched and Tempered

Category

Steel Bars

Scope

This specification covers hot-wrought and cold-finished quenched and tempered alloy steel bars.

Ok let's start with ASTM A434 chemical composition.

Chemical Composition

The grade of steel furnished shall be specified by the purchaser and shall be selected from the standard alloy grades in Table 2 of Specification A 29/A 29M

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Grade BC 63.5 to 114 mm

95 ksi (660 MPa) min

Learn more about what is yield strength.

Tensile Strength

Grade BC 63.5 to 114 mm

115 ksi (790 MPa) min.

Learn more about what is tensile strength.

Elongation (min.) 50 mm

0.16.

Learn more about what is elongation.

Reduction of Area (min. %)

0.45.

Learn more about reduction of area.

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 A434 currently ranks 11 in my yield strength index. This means there are other 10 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 A434 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.
