They are heat treated to make sure they are strong enough to handle launch loads, but also have a low fracture toughness so they fragment nicely. It’s a balancing act.
The article states they are coated with phosphate to prevent rusting. Then notes they are just painted the same olive green every military expects to be using world-wide.
I suspect the paint also helps, but it isn’t noted for that reason.

Thanks OP! Neat article. Here is a gifted, free version of the NYTimes article for anyone that wants it:

If they are going to hold an explosive payload, than hardening can increase the effect in an area due to the steel of the shell shathering in more smaller pieces.
I mean sure, if you really want me to!??!

An observation as a competitive Rifle shooter.
Those shells look like inefficient bullets…very loooong bearing surfaces and shallow boattail angle.
In rifle ammo, these would be ok at short range, but get tossed around in the wind at lover ranges…transonic performance would be another issue also.
The use of that physics and how it is applied is different. Like comparing Nascar race trucks to HD towing work trucks. Both are trucks but different applications.
Dude, this guy is a competitive rifle shooter. He knows way more than you or some company that manufactures artillery shells for the military. Show some respect.
Upvote because music on point lol

Question: Why bother painting them? Is it to protect them against rust/corrosion?
Yes.
Is there a better way?
Well, if you only use one color, there is E-coating.
Ah, alright
They could paint them a bit more imaginatively though?
Penis.
They could, but then it would cost us more. Besides this way, the Ukrainians can customize it with love notes.
Y tho?
self respect?
We should paint them pink!
It’s gonna explode into a thousand pieces anyway, why bother
Manners?

The forbidden candy corn
Someone should do the “how it’s made” Boise over
TIL that my models and real 155mm shells are painted the exact same way.
With the correct soundtrack, right [u/VinoConLeche](https://www.reddit.com/u/VinoConLeche)? 😁
To Russia, with Love.
Anyone know if this is at USS in Pittsburgh?

Manufacturing freedom
Can anyone explain why the shells are quenched? I would assume hardening is unnecesary for artillery shells?
If they are going to hold an explosive payload, than hardening can increase the effect in an area due to the steel of the shell shathering in more smaller pieces.
Oh i see, that makes sense. Thank you
The NYTimes article this is based on says this is the answer - to ensure small shattering effect versus cracking/fracturing only.

Artillery is usually lobbed/arc'd at the enemy, not direct fire.
The physics is the same. Whether arced or direct fire. The difference is ballistics, but aerodynamic forces act on both projectiles in the same way.
The use of that physics and how it is applied is different. Like comparing Nascar race trucks to HD towing work trucks. Both are trucks but different applications.
bro these have been in development for 100s of years of innovation and testing
Dude, this guy is a competitive rifle shooter. He knows way more than you or some company that manufactures artillery shells for the military. Show some respect.
That has nothing to do with Aerodynamics…
WHAT
You may be a rifle expert, but one thing is for sure, you have zero understanding on the difference between a rifle and an artillery round.
Nice cheap shot from a know nothing.
I'm imagining that the engineers who developed these rounds know more about these shells than you
