In this post I'll talk about AISI 431. First let's describe it and then have a look at its material's properties.
What is AISI 431?
AISI 431 is the most corrosion resistant of the martensitic grades. It also has excellent tensile and torque strength and good toughness.Application
Structural parts (that are exposed to marine atmosphere), aircraft fasteners and fittings.UNS Number

References
ASTM A240 and other references.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 431 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.
