In this post I'll talk about AISI 436. First let's describe it and then have a look at its material's properties.
What is AISI 436?AISI 436 is a variation of AISI 434 to which Columbium (Niobium) has been added to minimize ""roping"" or ""ridging"" during stretch forming operations.
ApplicationAutomotive exhaust applications. Stretch formed Aerospace Applications. Automotive Trim.
Ok let's start with AISI 436 Chemical Composition.
C, Carbon max.0.12
Mn, Manganese max.1.00
P, Phosphorus max.0.040
S, Sulfur max.0.030
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 436 currently ranks 32 in my yield strength index. This means there are other 31 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 436 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.
