ASTM A666 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A666. First let's describe it and then have a look at its material's properties.

What is ASTM A666?

ASTM A666 is a Specification for Annealed or Cold-Worked Austenitic Stainless Steel Sheet, Strip, Plate, and Flat Bar.

Category

Corrosion-Resisting and Heat-Resisting Steels

Scope

This specification covers austenitic stainless steels in the annealed and normally required cold-worked conditions for various structural, architectural, pressure vessel, magnetic, cryogenic, and heat-resisting applications.

Ok let's start with ASTM A666 chemical composition.

Chemical Composition

Type 304

C max.

0.08

Mn max.

2.00

P max.

0.045

S max.

0.030

Si max.

0.75

Cr

18.0 - 20.0

Ni

8.0 - 10.5

N max.

0.10

Now it's the mechanical properties turn:

Yield Strength

Type 304

30 ksi (205 MPa) min.

Learn more about what is yield strength.

Tensile Strength

Type 304

75 ksi (515 MPa) min.

Learn more about what is tensile strength.

Elongation (min.) 50 mm

0.4.

Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.

Hardness Requirements

Type 304

201 HB max.

Learn more about what is hardness.

Density

7480 - 8000 kg/m3 (around 7.9 g/cm3 or 0.285 lb/in3).

Learn more about density.

Elastic Modulus

180 GPa (26107 ksi) - 210GPa (30458 ksi).

Learn more about the Elastic Modulus.

Poisson's Ratio

Usually around 0.26 – 0.31.

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 A666 currently ranks 125 in my yield strength index. This means there are other 124 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 A666 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.
