gun is stainless is NOT corrosion but powder lead fouling not a big deal, is called forcing cone NOT nose cone LOL
That's the forcing cone and that could be erosion. To be sure of what it is, clean it with some copper or bronze wool. Pure copper Chore Boy (not copper plated steel) pot scrubber material also works well to remove lead. If it comes off, then it's lead. If the surface is clean and is scored, it's erosion.

Looks like mild erosion to me.
I must say, that is the cleanest forcing cone and frame on a revolver I have ever seen!

That’s because you’ve never seen a British nose cone before

As others have said, a 'nose cone' is an airplane part.
Your revolver forcing cone has no issues beyond needing a light cleaning.

Cheers I keep it clean , is this mild erosion anything to be concerned about or is it normal ?

Hmmm, never saw corrosion damage quite like that before! It could be but it could also be tooling marks. Did the forcing cone always look like that? IMHO it would take tens of thousands of rounds to cause that! HINT: Measure your barrel - cylinder gap! A BC gap over .007" or so might be the reason.
What loads are you shooting and what is the approximate round count?

I have revolvers far worse than that I shoot all the time. Two of my model 19s have the forcing cone worn halfway to the edge of the barrel. Those get 38 spl loads with lead bullets for the most part...and magnum use is rare, but with upper mid range cast lead handloads. No jacketed bullets. Not until I get the barrels set back and recut.
In my limited experience, the presence of those little "notches" interspersed throughout the mild wear indicate someone at sometime ran hot jacketed loads in that gun. I have seen that in guns that have had only a few boxes of 125 grain blue flame specials through them! Perhaps that had more to do with the make and model of the gun, the fit and finish and the metallurgy of the barrel. The magnums I have that I have used Lead bullets and heavier jacketed bullets in don't show those little "notches." But again, If I owned your gun I wouldn't worry about the wear I see there. I would worry more about finding enough small pistol primers in quantity and affordability to wear that barrel right to the edge! My two pennies worth anyway.

I normally shoot 98% lead or polymer coated lead bullets as I do reload my own. Rarely do I shoot metal jacketed bullets out of revolvers as I don't carry one any longer - went to a Micro 9. For range and target usage, polymer coated lead is what I've been using for a decade now. Could be one reason I have not seen that kind of forcing cone damage. I also use 158 grain bullets exclusively for reloading the .38 special cartridge. Even in magnum revolvers I shoot mostly .38 special ammo and when I do reload magnum bullets I load them to mid range magnum velocities with 158 grain polymer coated lead also. For the rare few times a year I shoot full power magnums, I usually shoot factory 158 grain JSP ammo from Federal.
That said, the forcing cone damage shown in the picture is basically more cosmetic than a real issue - I do agree with you. The muzzle is the real important area of a barrel as it is the last thing a bullet encounters prior to leaving the barrel and where it gets it's "final accuracy" from - if you will.
Not corrosion
That's not corrosion, rather it is erosion, and yes it is minimal, but it is damage caused by "flame cutting"! and yes, stainless does corrode, but it is much less likely, and it takes more time,, but expose it to salt spray, and you will see.. different alloys, experience "oxidation" at different rates...
oh, and that is not powder/lead fouling IMHO, looks very clean to me,, but lots of good information here, you are right in that it is not a major concern at the present, and not likely to be in the future. If however, the OP is calling the 125 grain Federal's the light magnum's, the lighter the bullet, with the hot loads, the much more likely they are to flame cut the top strap, damage forcing cones and rifling in the breech end of the barrel

I have seen erosion much worse than yours and the revolvers remained quite serviceable. A normal shooter likely will not shoot enough in their lifetime to have erosion become a problem. Something else will wear out first or they will run out of ammo money.

loads i use ; Vihtavuori VN105 light magnum loads - 125gr at 1350fps and mainly 158gr 1180 fps and 38spl's. had the gun for about 4 years. BC gap is .006

the only magnums loads i use are light loads , for example 125gr at 1350fps or 158gr at 1180fps . Also shoot 38spls . powder is Vihtavuori VN105

No, i reload light magnum loads - 125gr at 1350 fps or 158gr at 1180fps using Vihtavuori VN105

That does not look like erosion to me.
The forcing cone was cut, and then the rear edge was radiused by the smith who built it. Those look like tool marks to me.
