In this post I'll talk about SAE 1151. First let's describe it and then have a look at its material's properties.
What is SAE 1151?SAE 1151 is a resulfurized carbon steel that contains 0.51% carbon (approximately).
ApplicationThis kind of steel's main use is to increase machining speed. It allows automatic equipment to run without human interaction.
Ok let's start with SAE 1151 Chemical Composition.

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 1151 currently ranks 54 in my yield strength index. This means there are other 53 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:
Luz, Gelson. SAE 1151 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.
