Hello everyone.. I don't speak English very well so I hope you understand my question.... I bought the A400 Plus a year ago and discovered that there is a stellium technology and I don't know what it is useful for, as I read and did not understand that the length of the barrel is conical and helps to regulate shooting! But I want more clarification, thank you 🌹
 
Steelium is Beretta's term for the mettalurgy in its barrels. It is a made up word that does not mean anything. Think of "steel "and some other alloy ending in "ium" like chromium, gallium, berrylium, etc.
 
True the above. Put another way, It is the manufacturing technology to convert a 4140 type CrMo steel (more or less) into a Beretta barrel. It is not the steel itself. The bicycle analogy is Reynolds MnMo steel converted to 531 bike tubes. The 531 is the bike tube equivalent of Steelium gun barrels. It is the drilling, cold working and perhaps heat treating that makes the finished barrel special.
 
You put shelliums in the steelium barreliums, pull the triggerium and make boomium. Highly technical stuff.
 
Wow, that avatar really brought back memories. I used to watch Ultraman on one of the 4 TV channels we used to get.
well, on the one hand, the ultraman avatar is a homage to the decades I spent studying japanese martial arts. On the other hand, the avatar that most truly reflects me as a person is Fuzzy Lumpkin. Note the shootin iron and moonshine! ;-)

One thing not mentioned about the Steelium plus barrels on this thread is what the plus stands for. It’s something Beretta markets on their high end line. The plus refers to a “lengthened forcing cone”.

Supposedly, the lengthened forcing cone improves shot pattern. I have no evidence one way or the other if it’s true, but I will say I’ve had just as much success with my A300s as with the A400 XPs I’ve used.
 
From Beretta's website:

The ingredients of the stunning accuracy of the Beretta Steelium barrels are: the exclusive tri-alloy Beretta Steel (Ni, Cr, Mo) ...
Those three elements comprise shotgun barrel material other manufacturers commonly refer to as "steel".

To my knowledge only Beretta considers them factors that contribute to a barrel's accuracy.

And your English is perfect - better than many native English speakers.

It’s impossible to have steel without iron (Fe) and carbon (C), but the other elements make the ‘alloy’. Lots of stainless steel has nickel, and Chrome-Moly has chromium and molybdenum.

I’m not. metallurgist; however, I did take chemistry for a couple of years…
 
Steelium, Shmeelium, whatever...

All Steelium, Steelium Plus or Steelium Pro barrels are stamped with "Excelsior HSA Steel", just like always.
