In this post I'll talk about AISI 800. First let's describe it and then have a look at its material's properties.
What is AISI 800?AISI 800 is a nickel-iron-chromium alloy that resists carburization and oxidation at elevated temperatures.
ApplicationSteel production. Thermal processing fixtures. Power generation. Chemical and petrochemical processing equipment.
Ok let's start with AISI 800 Chemical Composition.
C, Carbon max.0.10
Mn, Manganese max.1.50
P, Phosphorus max.0.045
S, Sulfur max.0.015
Si, Silicon max.1.00

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 800 currently ranks 35 in my yield strength index. This means there are other 34 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 800 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.
