SAE 1074 Properties (Chem., Mech. & Rankings) 2022

 

In this post I'll talk about SAE 1074. First let's describe it and then have a look at its material's properties.

What is SAE 1074?

SAE 1074 is a high carbon steel with 0.74% carbon content, approximately.

Application

There is no known commercial application. However, they may be used in cutting tools such as knifes, drills or other tools that require some abrasion resistance.

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 1074 currently ranks 33 in my yield strength index. This means there are other 32 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:
