SilencerCo Scythe Ti failures

[HighUintas]

Yo dudes, I was watching this video and noticed that the can gets hot on the welds that fail first and stays hottest there longest. Kind of makes me wonder if it's a thermal cycling failure.

I have noticed that too just by feeling after shooting

Alright guys, I did a bit more research and have a theory. Silencerco posted on their website that it's made from grade 5 and grade 9 titanium. From some initial reading, it looks like grade 9 is easier to work with (stamp baffles) and has worse heat performance (shows up "reder" on a thermal imaging), and is a weaker titanium (more likely to fail).

So, I have a sneaking suspicion that what we're seeing is the welded joints between a grade 5 blast chamber and grade 5 first baffle fail when connected to the grade 9 baffle stack. I think it's also weakening at that weld the fastest because the grade 9 baffles don't handle the heat as well and Thermaly fatigue faster than anywhere else. As a result, I'd be willing to bet it's a long term design flaw of the can that everyone will experience at some point if they shoot it long enough.

I don't plan on taking it any further than this since I don't own one but think they're super cool and still may end up buying one....... links below if your interested.

@whoami-72 thata good research and seems very plausible. Thank you for sharing. I put another 100 rounds of 7mm prc through mine this week and now I am wondering if the failure is a accumulation of heat damage over time. I let mine cool 5 to 10 min between 8 shot strings and wonder if that will protect it.

Id honestly just shoot it like you normally would. I know I have and my Scythe is over 1000 rounds of 6.5cm, and 200ish 22" 300 win mag. I thought about attaching a small steel leader thru the ports on the end and about 50' of 100lb test to make it easier to find the end when it blows in half. Hasn't happened yet. This thread makes me wonder if it truly is isolated and not that many failures, based on how many have been sold. Internet search does not really provide too many other reports of them blowing apart.

I am continuing to use my as I normally would and hoping that if something happens, it happens during the off season and not on a shot on an animal.

People with failures are significantly more likely to report than those that have not had failures.

Holy balls this thread went down the nerd road on cans. Thanks, actually learned a bit about TI cans.

Though, I have wanted a Scythe, I think I'll be sticking with AB for now or try out a UM.
