AISI 202 Properties (Chem., Mech. & Rankings) 2022

 

In this post I'll talk about AISI 202. First let's describe it and then have a look at its material's properties.

What is AISI 202?

AISI 202 stainless steel is a type of Cr-Ni-Mn stainless. It is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness, and strength.

Application

Restaurant equipment. Cooking utensils. Sinks. Automotive trim. Architectural applications such as windows and doors. Railway cars. Trailers. Hose clamps.

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 202 currently ranks 24 in my yield strength index. This means there are other 23 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 202 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.
