AISI 317L Properties (Chem., Mech. & Rankings) 2022

 

In this post I'll talk about AISI 317L. First let's describe it and then have a look at its material's properties.

What is AISI 317L?

AISI 317L is a low carbon version of grade 317 stainless steel. It has the same high strength and corrosion resistance as 317 steel but can produce stronger welds due to the low carbon content.

Application

Condensers in fossil. Pulp and paper manufacturing. Nuclear fueled power generation stations. Chemical and petrochemical process equipment.

UNS Number

S31703

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 317L currently ranks 55 in my yield strength index. This means there are other 54 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.

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. AISI 317L 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.
