- This video is focused on the most commercially popular of the austenitic types or grades…… the 300 series of alloys.
What are the 300 series alloys? Well in this case we'll talk about 303, 304, 316, and 317. Plus all their variants. There are more grades but for today, that's what's on the docket.

From our introduction to stainless steels video last week, you know that Chromium is primarily what makes these "stainless'' steels corrosion resistant. Other elements also affect the properties of the commercial standard alloys.
In addition to the three digits in the alloy designation, there may be a suffix that indicates a modification of the basic alloy..... a suffix of "L" indicates a low carbon version of the grade.
A suffix of "F" indicates a free machining modification.
"S" indicates Sulfur added
"Se" for Selenium added.
Whenever we mention a % in the chemistry of an alloy, we mean percent by weight. So in an 18% Cr alloy, there would be 18 pounds of Cr in 100 pounds of the alloy.
Thank you for the hard work yall do. Please keep it up.😎
Much appreciate the kind words. Thank you for positive feedback!
Thank you, this is so informative
Thank you for the positive feedback. Thanks for watching.
Can you add 309
Did you do a video on the 30X stainless (aka HFS or Hard Frickin Stainless) used in Tesla's Cybertruck? Despite it being 30X, it is magnetic (Martensitic), supposedly from how the alloy is processed (either the heat treatment or the cold rolling/working that work hardens it). Would love a commentary video on a portion of the video where Sandy Munro of the Munro Live channel got a tour of a portion of the Cybertruck production line that shows the steel going from giant rolls to body panels.
Sounds like a good idea, I doubt however that we could gain access to the chemistry and physicals (an MTR) of that material so I could review it....that probably falls w/in their proprietary data as it's 30X not 304 or 316. I would do that video if the source data about their grade was available. If you have it, send it and I will do it! Thanks for watching.
