Silencer material comparison, weight vs strength

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

And also, why are some people using 304 if 316 has way better strength and properties?

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. :lol:

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.
So which one of the heat treated 4xxx series would be best to use for the tube? 4130, 4140, or 4340?

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:

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.

A great trip down memory lane indeed. I wonder if anyone used the idea of Nikasil plating on aluminum....who thought that up! 8)

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.

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.
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.
