Does anyone know how to get non painted parts back to that black metal look (Im sure theres a technical term

)
I've cleaned and polished some bits up , axles, bolts etc. but want them back to looking like original

Used to do stuff like this as an apprentice. You have to heat whatever it is up until it's bright red (damm hot) then put it in a large container of oil. You really need a large one as a small amount of oil will get very hot and possibly catch fire !
You can get chemical blacking which is used on gun barrels. I haven't used this myself but would save you having to heat stuff up a lot. There is always a risk that heating could cause things like axles etc to bend or crack.
I expect someone on here has found a good way to do it.
