ASTM A47 Properties (Chem., Mech. & Rankings)

In this post I'll talk about and give details about ASTM A47. First let's describe it and then have a look at its material's properties.

What is ASTM A47?

ASTM A47 is a Specification for Ferritic Malleable Iron Castings.

Category

Wrought Iron, Cast Iron, and Malleable Iron

Scope

This specification covers ferritic malleable castings for general engineering usage at temperatures from normal ambient to approximately 400°C (750°F).

Ok let's start with ASTM A47 chemical composition.

Chemical Composition

The chemical composition of the iron shall be such as to produce the structural and mechanical properties required by this specification.

Learn more about chemical composition.

Now it's the mechanical properties turn:

Yield Strength

Grade 32510

32500 psi min.

Learn more about what is yield strength.

Tensile Strength

Grade 32510

50000 psi min.

Learn more about what is tensile strength.

Elongation (min.) 50 mm

0.1.

Learn more about what is elongation.

Reduction of Area (min. %)

Not Required.

Learn more about reduction of area.

Hardness Requirements

Grade 32510

156 HB max.

Learn more about what is hardness.

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 A47 currently ranks 153 in my yield strength index. This means there are other 152 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 A47 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.
