SAE 52100 Properties (Chem., Mech. & Rankings) 2022

 

In this post I'll talk about SAE 52100. First let's describe it and then have a look at its material's properties.

What is SAE 52100?

SAE 52100 alloy steel is known as a high carbon, chromium containing low alloy steel.

Application

SAE 52100 alloy steel is used in bearings in rotating machinery.

UNS Number

My Material's Ranking Research

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 SAE 52100 currently ranks 84 in my yield strength index. This means there are other 83 materials that are more resistant.

Note: I've analysed 162 materials in order to create an yield strength index. Check my material's comparison post for more details.

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 and paste the information below into your assignment or essay:

Luz, Gelson. SAE 52100 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. This citation format is based on MLA.
