ASTM A128 Properties⚙️ (Chem., Mech. & Rankings) rev. 2022

In this post I'll talk about and give details about ASTM A128. First let's describe it and then have a look at its material's properties.

What is ASTM A128?

ASTM A128 is a Specification for Steel Castings, Austenitic Manganese

Category

Steel Castings

Scope

This specification covers Hadfield austenitic manganese steel castings and alloy modifications.

Ok let's start with ASTM A128 chemical composition.

Chemical Composition

Now it's the mechanical properties turn:

Allowable Stress

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

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 A128 currently ranks 137 in my yield strength index. This means there are other 136 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 A128 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.
