In this post I'll talk about SAE 1070. First let's describe it and then have a look at its material's properties.
What is SAE 1070?SAE 1070 is a high carbon steel with 0.70% carbon content, approximately.
ApplicationThere 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.
Ok let's start with SAE 1070 Chemical Composition.
P, Phosphorus max.0.040
S, Sulfur max.0.050

My Material's Ranking ResearchWhile 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 1070 currently ranks 38 in my yield strength index. This means there are other 37 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.

CitationWhen 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:
