In this post I'll talk about SAE 4150. First let's describe it and then have a look at its material's properties.
What is SAE 4150?SAE 4150 alloy steel is a higher carbon variation of chromium, manganese, molybdenum 4100 low alloy steel.
ApplicationThey are used in oil and gas, energy, construction and the automotive industries because of its corrosion resistance and high-temperature and tensile strength.
Ok let's start with SAE 4150 Chemical Composition.
P, Phosphorus max.0.040
S, Sulfur max.0.040

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 4150 currently ranks 60 in my yield strength index. This means there are other 59 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:
