Carbon steel brake rotors is the choice for high end sports cars. Carbon steel runs much more colder and have high heat tolerance. Im pretty sure it's the same with these carbon steel barrel. Correct me if I'm wrong.
stainless steel will wear faster than a 4150 carbon steel barrel with chrome lining especially when hot.... and if you dump magazines it will eat up the throat.. this is why all machine gun barrels are carbon steel,, that being said i have ss barrels with thousands of rounds that are still accurate
Yes, I cheaped out and got a blued 10/22 to save money, but now I'm getting rid of that barrel to buy a stainless. It's cheaper to start with stainless bc blued guns are a forever rust pit.
This guy needs to learn a bit more about steel. S.S. doesn't corrode as easily as due to chromium. S.S.'s have at least 10.5% chromium and show passivity in oxidizing environments. He is somewhat right in declaring this is associated with low carbon as some tool steels have high chromium content but also high carbon content and therefore oxide easily. The chromium when in contact with oxygen produces chromium oxide which much like aluminum oxide doesn't expand and flake away like rust (iron-oxide). This thin film layer protects the remaining mass from oxidizing. However, S.S. are still prone to corrosion from pitting in certain environments (chloride based), crevice corrosion, intergranular attack, and galvanic corrosion. Furthermore, they have a wide range of hardness which can be conducted through cold rolling and heat treatment so their machineability is similar to carbon steels, and addition of different alloys such as nickel, but welding is more difficult. Its more expensive due to the addition of alloys such as chromium and nickel. Source: Engineering Materials Properties and Selection 9ed
As a machinist it has cut different styles of Steel and different styles of stainless steel sorry to say this but b*******. It takes more time to cut a stainless steel barrel because it's gummy it gums up the tools and everything else and nearly lost my job because the plates had have been five tenths of a thousand tolerance when I machine them on the lathe machine. But when I moved him over to the mill they started a warp due to the drilling process making it hot because it was gumming up the drill. 410 or 416 stainless has low carbon rate 316 stainless has near no carbon if I'm correct on that. Your Chrome Moly barrels are going to be harder to machine than 316 or 410 stainless. What makes stainless steel stainless steel is the nickel content into it.
Can only speak form my experience , but the carbon steel shoots more consistently when cold. First shot from a cold stainless barrel , wide of the mark.
Thanks for your video, I think I can see why this is a bit of a dilemma...The gun manufacturers make high carbon and stainless barrels. Both are good, but stainless is more costly to produce and as a result requires higher price to make a profit. Yet by doing this they do not make as much off their regular carbon only steel barrels because which they can't sell for a premium as it's very clear they are inferior to the stainless steel one's. In essence they have to sell stainless at a close to cost rather than selling them for a premium they choose focus more on their carbon steel barrels as they make a larger profit form them due to their low production costs...or something like that?
Lee Harvey Oswald Yes stainless steel is indeed tougher to machine it is harder on equipment although it doesn't take heat treating as well so untreated a stainless steel is harder but in general carbon steel will be harder after heat treating. All said there are unlimited alloys of each and it really depends on what your comparing to what. The real question is what is better for a rifle and the only advantage I can say for certain is stainless steel is much more rust resistant.
ryan ramin, you clearly don't have personal experience with stainless and carbon steel barrels... my dad has been a machinist for over 40years at Timet Metals where they produce titanium for places like Boeing, and we have worked on both types of barrels whereby there's a significant difference in hardness when machining them
