In this post I'll talk about N08020. First let's describe it and then have a look at its material's properties.
What is N08020?N08020 is a low-carbon, niobium-stabilized austenitic nickel - iron - chromium alloy with additions of molybdenum and copper.
ApplicationProduction of plastics and synthetic fibers. Chemical and petroleum processing equipment. Mixing tanks. Heat exchangers. Process piping.
Ok let's start with N08020 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 N08020 currently ranks 25 in my yield strength index. This means there are other 24 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. N08020 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.
