HY-100 or HY-80 steel question

Don't have a clue what that material is. Designations are different here in the States. Can you describe it in better detail?

Possible by induction heating, depending on the alloy, but likely not economical, nor necessary. Reason?

Fun to drill, too! Have you worked with titanium?

Heavy duty steel

These are both use for submarine pressure hulls. The 1960'w era built boats that I was on use the HY-80. I belive that they went to HY-100 or better with the Posiedon class missile subs in the 1970's.

It is possible to make a titanium barrel, but they are hard to machine, difficult to rifle, and they don't shoot very well. It's been tried, and it don't work very good.

There are no Titanium barrel guns. They don't work. What they do is make the barrel shroud from Ti and use a liner of some other material, such as stainless.

If you read your referenced article, it even states the same:

Like all other Taurus Total Titanium and MultiAlloy revolvers, the Tracker barrel is constructed of forged titanium with a high-tensile-strength stainless bore liner. Titanium is much more elastic than steel, which makes it extremely durable but also means an all-titanium barrel will not hold rifling. It stretches flat with the bullet's pressure impact. The stainless-steel bore sleeve solves that problem

HY80, I believe, is the alloy used in submarine hulls. It is also known as MIL S-16216. That spec means that it comes hardened and tempered to 80 ksi yield strength (thus the 80 in HY80). Similarly HY100 is hardened to 100 ksi yield strength.

Don't know nothin' about rifle barrels, but that's what I know about those alloys.

HY-80 and HY-100 are US desinations for steels commonly used for submarine hulls. I think the name stands for high yield 80,000 lbs yield strength. I did not answer when I first saw this thread. I am not sure what makes a good rifle barrel steel. My first guess is resistance to erosion for wildcat cartridges that blow a lot of powder down the barrel and have short barrel life. And I have no idea of how HY-80 would be for that. For a target rifle, I would think a steel that machines well would make a better barrel.

Thanks to all for the enlightenment. Considering my lack of experience in marine vessels, it doesn't surprise me that I had never heard of the material.

Heck, I'd just wire EDM the barrel bore. Get the rifling done that way too. Step one, drill a long thin deep hole down the center of the stock....

And I thought it might be difficult! :-)
