ASTM A313 Properties⚙️ (Chem., Mech. & Rankings) rev. 2022

In this post I'll talk about and give details about ASTM A313. First let's describe it and then have a look at its material's properties.

What is ASTM A313?

ASTM A313 is a Specification for Stainless Steel Spring Wire

Category

Spring Wire

Scope

This specification covers austenitic and age-hardenable stainless steel round spring wire intended especially for the manufacture of springs.

Ok let's start with ASTM A313 chemical composition.

Chemical Composition

Mn max.

2.00

P max.

0.045

S max.

0.030

Si max.

1.00

Cr

17.0 - 19.0

Ni

8.0 - 10.0

N max.

0.10

Now it's the mechanical properties turn:

Tensile Strength

Type 302 Class 2

290 - 340 ksi (2000 - 2345 MPa)

Learn more about what is tensile strength.

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 A313 currently ranks 148 in my yield strength index. This means there are other 147 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 A313 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.
