In this post I'll talk about AISI 429. First let's describe it and then have a look at its material's properties.
What is AISI 429?AISI 429 is a ferritic steel that possesses good corrosion resistance, and weldability.
Ok let's start with AISI 429 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 429 currently ranks 68 in my yield strength index. This means there are other 67 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 429 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.
