ASTM A671 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A671. First let's describe it and then have a look at its material's properties.

What is ASTM A671?

ASTM A671 is a Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures.

Category

Steel Pipe

Scope

This specification covers electric-fusion-welded steel pipe with filler metal added, fabricated from pressure vessel quality plate of several analyses and strength levels and suitable for high-pressure service at atmospheric and lower temperatures.

Ok let's start with ASTM A671 chemical composition.

Chemical Composition

Grade 65

C max.

0.24

Mn

0.85 - 1.20

P max.

0.035

S max.

0.035

Si

0.15 - 0.40

Now it's the mechanical properties turn:

Tensile Strength

Grade 65

65 - 80 ksi (450 - 585 MPa)

Learn more about what is tensile strength.

Elongation (min.) 50 mm

0.23.

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 A671 currently ranks 163 in my yield strength index. This means there are other 162 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 A671 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.
