Custom firing pin in INCONEL

[DeepSeaDiver]

Good morning, after breaking several firing pins, along with an Italian gunsmith we made from a superalloy INCONEL (Inconel - Wikipedia)
different firing pin, tested and working.

That is oxidation and corrosion resistant material. How is it under compression and high stresses? I just don't see how a material like that can stand up as a firing pin as well as steel.

 

[DeepSeaDiver]

This type of material is characterized by high resistance to wear and tear and produces finished parts that can boast excellent tolerance to mecccanici and thermal stress even when exposed in the environment conducive to oxidation.

I worked at a forge plant that forged high pressure piping and usually the metal was Inconel. That is some expensive metal and it is for high heat and wear resistance.

coast, it is difficult to work but at least it does not break

as seen on the photos, tooling marks on the pin. dirt/ lub from the 22's will adhere to/ in the marks. machined submarine valves that were Inconel, can be polished, but will mark, but scratches can be polished w/ caution.

Saturday did the first test with 500 minimag 40 grs, 36 grs and cci blazer, all okay.
next Saturday another test with 500 sellier & bellot HV
other custom firing pin were given to try to agonists shooters for further testing

Interested in this.

Looking at the date of the OP's last post, it looks like this has died a death. Let's hope VQ or another company get into making them....the only ones that you could get in the UK were $70 and they are no longer available.

It looks like a pretty simple piece.

If necessary, a local job shop could probably reproduce one in tool steel. Could be $100 in labor, though.

S&W should be selling firing pins, BCG and all the rest.

I have a spare firing pin, been sat in my spares box for best part 2 years. Got it just after I got my Smith, several thousand rounds later and still not fitted it, good to know it's there though.

How in the world are yall breaking firing pins..... Iv got 8-10K rounds through my gun with zero problems....

Unfortunately like anything mechanical, they do break. I have a 15-22 with over 100k thru it and I am on my 6th firing pin. I'm getting about 18k before failure on average.

Now my CMMG conversions are only getting about 10k before the firing pin fails, but the part is much easier to find.

Always good to have spares on hand.

Beryllium copper is my go to material for long lasting firing pins. On the rare occasions I need to fabricate one. Weirdly, I think Charter Arms were the first to do it. "Never break" firing pins for "little use" revolvers....

Easier to machine by far than Inconel. Just don't breathe it.

There are three 15-22s in my family. Mine has over 20k through it, the rest over 10k ... all have the original firing pin.

Great another thing I have to get, Just in case.....

LOL

Guess I'm half way to a new firing pin.
