In this post I'll talk about AISI 420. First let's describe it and then have a look at its material's properties.
What is AISI 420?
AISI 420 stainless steel is a high-carbon steelthat can also be hardened through heat treatment. This grade has the highest hardness among all the stainless steel grades with 12% chromium.Application
Shear blades. Needle valves. Surgical equipment. Cutlery.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 420 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.
