SAE 1139 Properties ⚙️ (Chem., Mech. & Rankings) rev. 2022

 

In this post I'll talk about SAE 1139. First let's describe it and then have a look at its material's properties.

What is SAE 1139?

SAE 1139 is a resulfurized carbon steel that contains 0.39% carbon (approximately).

Application

This kind of steel's main use is to increase machining speed. It allows automatic equipment to run without human interaction.

UNS Number

G11390

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. SAE 1139 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.
