I'm keeping an eye on that Mack with the early Cummins and the Unit shovel with it. Those would come home with me if they needed to.

A friend of mine runs the yard there. He said it’s about 40,000lbs.
Surface support ship Benny engine most likely.

Thanks Jared. I was pretty sure it was F-B from the shape of it. No clue beyond that.

I got the backstory on these Fairbanks Morse engines.
I drove up and the owner was out front and came over to tell the tale. He gets two sets of them a year on average.
They are the backup genset engines from the early nuke subs that they are breaking up at Bremerton. He says they have to stay in country and can't be exported to China, so they go back east by rail to somewhere that can smelt all the good stuff in there.
Apparently he gets a large volume of inconel that also has stringent requirements on final disposal.
Note the custom artwork on the head on this engine. The crews have fun with it.
Now we have the official weight in paint pen.
He says the big shear on the 700 will reduce this engine in 20 minutes. The 450 shear had trouble with the crankshaft.

Inconel-high nickel content, commonly used in intake/exhaust valves on high output engines.
Would be a premium recyclable these days, years back no one wanted anything with sodium
filled valves in recycling, we use to strip the exhaust valves.

you KNEW that was where I was going with the thread title. Thanks for validating the reference.

There is a melt shop in Pa that buys navy scrap for it's alloys, no need to add
so much new when making ingots, if you can buy scrap that already has it in.
They mentioned armor plate having IIRC 3% inconel.

Inconel is suspectable to stress-corrosion cracking under moderate preloads in saltwater, thus there's not much Inconel on a submarine. The only Inconel pipe I'm aware of is the overboard diesel exhaust. If you were to weigh all the Inconel from a recycled submarine at once, it might equal a ton or two tops.
The stated prohibition on export is HY-80 - which submarines have a whole lot of. What's strange is that any competent steel foundry can produce HY steel. I think the real issue is that we don't want foreign nations getting their hands on cutup submarine sections.
The red diesel pictured above weighs 30,600 pounds (Shop 72 marks the component-weight with paint marker upon removal)

The nickel alloys that I know of in subs usually pertains to the nuke piping and heat exchanger/boilers.
Also some other alloys in the radar domes.

The scrap guy said he gets inconel, he did not say it came from the subs.

Reactor compartments are sealed up and sent to Hanford. They are not sold to the public.
When the USS Long Beach was getting cutup a while back, there was a sealed-bid selling 7.5 million pounds of HY-80, HTS, and OS steel (about 25% of the ship) for a duration of time. May have been a 6-month recycling contract?
Heat exchangers, condensers, and any piping containing seawater will be Cu-Ni. Hydraulic pipe will typically be 300 series CRES. Ventilation is aluminum, wire is copper, everything else (aka the overwhelming vast majority of any ship or submarine) will be carbon steel - of some alloy.
For the high-nickel alloys - the Navy uses quite a bit of Monel, to some degree K-Monel - but uses very little Inconel. Monel and K-Monel hold up exceptionally well to seawater, whereas Inconel does not.
If you want a top-of-the-line turbocharger exhaust manifold, or heavy-duty engine valves, you make them from Inconel. If the recycle guy is getting Inconel that requires export controls, it's probably not coming from the Navy.

I don't care. I took him at his word that he also handles a volume of inconel.
I do recall marine shafts made with inconel. My dad's boat shaft was inconel.

We have similar interests Skyking. We live in the same State. We'd probably get along great if we ever met face-to-face.
Life's too short to hold a grudge over perceived insults.

Sounds like a playdate to me.

Yeah, but you can't get along online, so why don't you just ignore any threads that skyking1 starts?
I thought he was more than gracious in his last thread on his house build , when you didn't take a hint. I'm not sure why you're so intent on pushing it. Maybe just let it go.
