ASTM A615 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A615. First let's describe it and then have a look at its material's properties.

What is ASTM A615?

ASTM A615 is a Specification for Deformed and Plain Carbon Steel Bars for Concrete Reinforcement


Steel Bars


This specification covers deformed and plain carbon steel bars for concrete reinforcement in cut lengths and coils. Steel bars containing alloy additions, such as with the AISI and SAE series of alloy steels, are permitted if the resulting product meets all the other requirements of this specification.

Ok let's start with ASTM A615 chemical composition.

Chemical Composition

The percentages of carbon, manganese, phosphorus, and sulfur, shall be determined. The phosphorus content thus determined shall not exceed 0.06 %.

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Grade 60

60 ksi (420 MPa) min.

Learn more about what is yield strength.

Tensile Strength

Grade 60

90 ksi (620 MPa) min.

Learn more about what is tensile strength.

Elongation (min.) 203.2 mm

9% (Bar no. 3).

Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

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 A615 currently ranks 35 in my yield strength index. This means there are other 34 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?

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 A615 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.
