Silencer material comparison, weight vs strength
Re: Silencer material comparison, weight vs strength
And also, why are some people using 304 if 316 has way better strength and properties?

Re: Silencer material comparison, weight vs strength
The strength difference for 304 vs 316 is not much at room temp but does become significant at elevated temps.

Seamless 316 is ~ 2x the cost of 304 so there is a cost factor. The typical 223/308 can with a wall thickness of 0.065 in
is plenty strong with 304 ss. If I were planning on getting a can real hot then 316 would have some benefit.
Now if you want real performance improvement use 17-4 H900 or 300 maraging steel. Good luck finding tubing in those alloys.

Re: Silencer material comparison, weight vs strength
So which one of the heat treated 4xxx series would be best to use for the tube? 4130, 4140, or 4340?BinaryAndy wrote:Capt.

The material is readily available (even in seamless tube), inexpensive, and easy to machine. With the right heat treat it's about the right hardness, and the yield strength is outstanding. A 4140 tube can actually be made lighter than a Ti tube for the same diameter and bursting pressure.

Not sure if you have a reliable source for those materials, but in case you need one here's a company with Aerospace Grade Metals:
6Al-4V Titanium: https://fighterjetmetals.com/2020/11/11/ams4928/
17-4 Stainless Steel: https://fighterjetmetals.com/stainless-steel/

Welcome FIghterjet1995 and thank you for not just
the good information but recalling a past post
with the names of former members 'long gone'.
Pleasant reminder, felt like WW2 vet neighbor
who every five years would vacation with his wife
and a remaining few friends to Normandy France to
see where their dear buddies lay.
Great guys in past posts here. This is what makes this
site so special.

Re: Silencer material comparison, weight vs strength
A great trip down memory lane indeed. I wonder if anyone used the idea of Nikasil plating on aluminum....who thought that up!
fighterjet1995 welcome. Unfortunately the suppliers listed do not sell small quantities.Often for a single suppressor only a cutting may be needed.Its best to ask for materials as some of us have odds & ends.

Re: Silencer material comparison, weight vs strength
I'm still around and check the forum regularly I just don't post much. Sadly we have lost some of the 07/SOT posters and the forum sees much less activity these days.Historian wrote: ↑Mon Mar 15, 2021 7:54 am Welcome FIghterjet1995 and thank you for not just

As for sourcing the "better alloys" they can be found as bar stock easily at https://www.onlinemetals.com/ or McMaster-Carr but the prices are high. Some places have them as 'cut offs' at better prices but stock at hand is hit & miss.
What I never could find is a source of 17-4 tubing or pipe that didn't require buying a truck load. Would be nice to have a 0.035 wall can that could take high power cartridge pressures with ease.
