In this post I'll talk about SAE 1548. First let's describe it and then have a look at its material's properties.
What is SAE 1548?SAE 1548 is a high manganese steel with approximately 0.48% carbon content.
ApplicationIt is used in industries requiring high strength, low temperature toughness and wear resistance.
Ok let's start with SAE 1548 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 1548 currently ranks 40 in my yield strength index. This means there are other 39 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 1548 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.
