ExtremeShot Posted January 17, 2010 Share Posted January 17, 2010 I made this comp out of stainless steel and it has only seen maybe 500 rounds. In order to reduce the length a little I decided to reduce the distance between the ports to 50 thou instead of the usual 100 thou. I was cleaning my gun this morning and noticed that the metal in the first port was bent (pushed forward). Although it's irritating that I'll now have to make another comp (this comp worked real well), it's pretty neat seeing that the gases can deform stainless steel like that. It's also pretty neat seeing proof that the gases are pushing against the vertical surfaces. Anyway, I thought you guys would find this interesting.

ong45 Posted January 17, 2010 Share Posted January 17, 2010 Wow that's cool. Am i right to assume that stainless is a bit softer that regular steel ? thanks for posting that. Link to comment Share on other sites More sharing options...
BSeevers Posted January 17, 2010 Share Posted January 17, 2010 Maybe the next one will be carbon? Link to comment Share on other sites More sharing options...
ExtremeShot Posted January 17, 2010 Author Share Posted January 17, 2010 Yeah, stainless is softer (don't know the comparison of stainless versus carbon off-hand) but no, I won't make the next one out of carbon. I'll just make the distance 100 thou like before. They don't bend at 100 thou. Link to comment Share on other sites More sharing options...
Pezco Posted January 17, 2010 Share Posted January 17, 2010 It is pretty wild that the pressure can move the metal like that. Link to comment Share on other sites More sharing options...
BrianH Posted January 19, 2010 Share Posted January 19, 2010 If you're using something like 303, 304, 316...like that....yield strength is pretty low. Like 20-30k psi. Try 17-4. Now you're up around 120k psi or so. Link to comment Share on other sites More sharing options...

Now you're up around 120k psi or so. Yep, 17-4 has a much higher yeild then the more common SS as mentioned above. Find some double aged and it's even higher. Use it reguraly at work for custom load cells. MDA Link to comment Share on other sites More sharing options...
