SAE 1050 Properties ⚙️ (Chem., Mech. & Rankings) rev. 2022

 

In this post I'll talk about SAE 1050. First let's describe it and then have a look at its material's properties.

What is SAE 1050?

SAE 1050 is a medium carbon steel with 0.50% carbon content, approximately.

Application

There is no known commercial application. However, they may be used in rails, gears and parts requiring high strength and hardness.

UNS Number

G10500

Ok let's start with SAE 1050 Chemical Composition.

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 1050 currently ranks 95 in my yield strength index. This means there are other 94 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 1050 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.
