In this post I'll talk about AISI 316L. First let's describe it and then have a look at its material's properties.
What is AISI 316L?AISI 316L offers robust and high temperature tensile, creep and stress-rupture strengths, together with outstanding formability and weldability.
ApplicationCoils and sheets. Wires. Pipes and tubes. Seam welded, cold redrawn and annealed. Plates and Round bars. Seam welded and cold redrawn forms.
Ok let's start with AISI 316L Chemical Composition.
C, Carbon max.0.030
Mn, Manganese max.2.00
P, Phosphorus max.0.045
S, Sulfur max.0.030
Si, Silicon max.0.75

AISI Ranking Research (Stainless Steel)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 AISI 316L currently ranks 74 in my yield strength index. This means there are other 73 materials that are more resistant.
Note: I've analysed 77 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. AISI 316L 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.
