AISI 403 Properties (Chem., Mech. & Rankings)


 

In this post I'll talk about AISI 403. First let's describe it and then have a look at its material's properties.

What is AISI 403?

AISI 403 is a corrosion and heat resistant 12% Cr martensitic stainless steel.

Application

Turbine parts and compressor blades.

UNS Number

S40300

Ok let's start with AISI 403 Chemical Composition.

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 403 currently ranks 65 in my yield strength index. This means there are other 64 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 403 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.
