ASTM A135 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A135. First let's describe it and then have a look at its material's properties.

What is ASTM A135?

ASTM A135 is a Specification for Electric-Resistance-Welded Steel Pipe.


Steel Pipe


This specification covers two grades of electric resistance- welded steel pipe in NPS 2 to NPS 30 inclusive, with nominal (average) wall thickness up to 0.500 in. (12.70 mm), inclusive, and in nominal sizes NPS 3/4 to NPS 5 inclusive with nominal (average) wall thickness 0.083 in. (2.11 mm) to 0.134 in. (3.40 mm).

Ok let's start with ASTM A135 chemical composition.

Chemical Composition

Grade A

C max.


Mn max.


P max.


S max.

Now it's the mechanical properties turn:

Yield Strength

Grade A

30 ksi (207 MPa) min

Learn more aboutĀ what is yield strength.

Tensile Strength

Grade A

48 ksi (331 MPa) min

Learn more aboutĀ what is tensile strength.

Elongation (min.) 50 mm


Learn more aboutĀ what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more aboutĀ reduction of area.


7800 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).

Learn more aboutĀ density.

Elastic Modulus

190 GPa (27557 ksi) - 210GPa (30458 ksi).

Learn more about theĀ Elastic Modulus.

Poisson's Ratio

0.27 ā€“ 0.30.

Learn more about theĀ poisson ratio.

Allowable Stress

Depends on the project (And its factor of safety).

Learn more about theĀ 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 A135 currently ranks 100Ā in my yield strength index. This means there are other 99 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 A135 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.
