In this post I'll talk about SAE 12L15. First let's describe it and then have a look at its material's properties.
What is SAE 12L15?
SAE 12L15 is a resulfurized and rephosphorized carbon steel (with added lead) that contains 0.15% carbon (approximately).Application
Applications include high-speed screw machine products where superior machining characteristics of this steel can be fully utilized.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 12L15 currently ranks 44 in my yield strength index. This means there are other 43 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.

References
ASTM A29 and other references.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:
Luz, Gelson. SAE 12L15 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.
