A machinists comment on stellite....

[wacki]

Just picked up my Osprey. I love it!

While at the shop one of the guys running my forms is a machinist during the week and said satellites are very brittle. He said putting stellites in suppressors was a bad idea and went on how the heating and cooling cycles can cause it to crack. He's had similar issues with Gem-tech's inconel though. So I did a quick google on stellites and this PDF says not all are brittle:

Just wondering if SilencerCo has any other comments to make. I'm pretty sure you guys have all your ends covered (+ lifetime warranty) but it doesn't hurt to ask.

Gemtech's inconcel problems are failure of design and implementation of said design not the metals used.

Stellite was / is used in some. 50 barrels, valves and various applications that resist high temps & erosion. Hastoloys & inconel are great materials as well but not always the best choice in every condition. It comes down to design intent & conditions.

Only if you are comparing it to a soft stainless like 304.
We do have our ends covered and our lifetime warranty covers you.
Stellite is superior to inconel as a suppressor material in every way that matters. A Stellite baffle will be glowing red and taking abuse long after an inconel baffle yields and collapses. I consider Stellite the perfect rifle suppressor baffle material. Erosion resistant and strong even when glowing red hot.

Henry you perfected the blast baffle now fix your dealer locator on the website. I keep getting deleted along with the other dealers in my area.

It is good enough for me to buy two Specwars.

Just curious, which Stellite alloy (1, 3, 4, 6, 12, 21, etc) do you guys use?

Do the Specwar and Saker both use the same type alloy?

The Stellite we use is proprietary.

The Saker and the Specwar use the same Stellite.

Early M60 barrels had stellite liners.


Keep in mind using stellite or inconel in a general sense is just like saying steel in a totally general sense... the many various alloys of each that have totally different intrinsic properties many of which are great for one purpose but horrid for another.

So I'm just a noob here in the forums but does SiCo have patents on this proprietary stellite material? Or even a pending number? That might be able to dispel the misconceptions in performance around the generic term "stellite" that is used in the suppressor.

We use stellite 21 in nuclear steam/feedwater valve seats at work. Stellite 6 is also commonly used but we have found 21 resists cracking better.

Also used in some 1919 barrels.
