Awesome job by MMI giving insight into the Ferritic Stainless Steel compositions. This is great material science information for all interested in metallurgy as well. A Big Thank! (An Awesome Video!)

Hey Michael! I watched your videos on with Gary on 300 and 400 series stainless steels and I was wondering if you could help me out with a question, or two. I am very interested in cryogenic treatment of steel, specifically in the application of gun barrels. I've seen how it can reduce overheating and allow for cooler barrel temperatures after making repeated shots. I spoke with someone at a company who also mentioned how it can extend barrel life and how the overall effects very in carbon steel and stainless steel. Carbon/Chromoly seeing a 30% improvement and Stainless seeing only 10% longer barrel life. I was hoping to yours and Gary's take on cryogenically treating a rifle barrel made from either chromoly or stainless steel, and weather or not it's worth it. I'd really like to gain any insight either of you have with regards to corrosion resistance, especially in the case of the stainless steel which is already somewhat corrosion resistant (not sure what grade is typically used for guns made from stainless but it's gotta be 400 series at the least). Great video's, thanks again!!
Here's what I can say: Only certain grades would benefit from a cryogenic step in the heat treatment of the barrel. Cryo assures full transformation during hardening that can improve wear characteristics in those alloys. So its not only a cryo treatment in the question, its also what alloy are we talking about and /or is it just marketing buzz making the superior claim...I would not expect any effect on keeping a barrel cooler with multiple shots fired.

This is Great! thank you Michael
Im a welding engineer right now working with ferritic stainless 439
How to make nickel free stainless steel of 304 with stretchable possible? Please sir guide me
