I think I was given some bar with coloured paint on one end, that will tell the grade if I'm not mistaken?

Lookup Abom79 chip control vids on YouTube. Massive heavy cuts with HSS no problem at all.

..
Had a similar conversation several times with the bloke who let's me use his toys..... proper old school engineer and very good, but 'ally does not need lubrication'.... One day I got fed up cleaning tooling and started with Wd40. .. not had any pick up on lathe or mill since ..... its only 6082 so nothing special but does seem to like picking up on tools
Imo the correct way is what works, not what we always did...

As mentioned watch for hi sulphur steels they make cutting, turning milling a lot easier. Down side is they don't polish very well.
But there is something in what you say about steel quality as a side note, cheap steel will have hard and softer zones and less refined grain.

It would if you could find out who supplied it, the problem is that different suppliers use different colour codes.
I used to raid the Parker Hannifin offcuts skip which is full of bar ends in various sizes and flavours, I asked the storeman if he had a cross reference for the colours but he said that they had a number of suppliers who all used different colours, an example was White could be en8, or leaded free cutting steel.

I just had a little play with it, I'll upload some pictures later.
I ground a little radius on the tool and tried heavier cuts on a good bit of steel. At 0.008" per rev, I was able to get to 0.05" off the radius with a reasonable (Not great) finish. Then I slowed it down to 0.002" per rev and was able to go up to 0.15" off the radius with a similar finish
. This seemed a bit excessive and probably not good for the tool but it didn't sound or behave like it was struggling at all, I think it could have gone to 0.2" or even a quarter of an inch
if I was braver.
