In this post I'll talk about XM-18. First let's describe it and then have a look at its material's properties.
What is XM-18?XM-18 has a moderately high tensile strength among other stainless steels.
ApplicationXM-18 Stainless Steel plate - coil is widely used in general service industries (petroleum, food, chemical, paper, fertilizer, fabric, aviation and nuclear).
Ok let's start with XM-18 Chemical Composition.
C, Carbon max.0.03
P, Phosphorus max.0.045

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 XM-18 currently ranks 8 in my yield strength index. This means there are other 7 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. XM-18 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.
