It's been forty years since I've had classes in metallurgy, but IIRC we're looking at normalizing (stress releaving, increasing ductility and equalizing grain size) to full scale annealing which reduces hardness.
Recovery annealing, stress relieving if you want to call it that, is just as the name suggests, limits annealing to the recovery phase. There's no change to the grain structure. Full annealing, normalizing, etc, involve changes (recrystalization and grain growth) to the grain structure. That's why you see larger changes to the material properties with those processes than with recovery annealing.
Thanks for the clarification đź‘Ť I pulled out my old text book to refresh my memory. It discusses yellow brass but doesn't have a chart that shows how different temperatures affect the properties of it.

I hear ya! I have to dig out a book now and again for a memory refresh too
This document is old but it's a gold mine of information. It doesn't spell out the answers for reloaders but for technically minded people that are interested in the topic there's a lot to unpack in it. If you click on the PDF version that's the easiest to read. https://www.ideals.illinois.edu/items/5215
Easy doesn't have to be hard, and simple doesn't have to be complicated.
$70 in parts and a Sunday afternoon invested.
~In return I get a good consistent anneal after every firing that gives me .001" shoulder bumps and .002" neck tension, my personal requirements for precision handloads. ~I get the job done in much less time than any other method I've used, or any other method I've seen lauded on the interwebs. ~I didn't spend a small fortune to have what I needed. ~I have no burnt fingers, none, nada, zip.
Nothing less. Nothing more.

Very nice setup. Can you share your parts list? I use drill, socket, torch and metronome app, or I have a salt bath setup that I like except for set up time. But I also like projects so maybe I need a home made annealing machine as well ha ha.

So far, I've been really happy with my homemade induction annealer.
I ordered on Tuesday and received it today talk about fast shipping. The only thing that I could say was different than the video was that he said they opened the torches and tested them and didn’t. I’m fine with it but someone will complain and I can’t wait to try it.
I like what Al is doing. I don't have a ring of fire device. I put a case in a drill and rotate the brass as I hold a torch on the neck. Drop the case into water when "done". I used to used a melting pot - molten lead and that worked. The accuracy improvement has been significant with some 222 loads.
That (Al's ring-o-fire) may work great but it ain't fer the clumsy among us. I'd best stick to my machine.
Don't be the darkness.
America will perish while those who should be standing guard are satisfying their lusts.
I found with the candle method, in my case with an alcohol burner, and 750 Templaq, I found I didn't get a colour change before my fingers got too hot.
I ran into the same thing and that is what motivated me to buy an Anneal-rite 15 years ago.

Not being married to any particular political party sure makes it a lot easier to look at the world more objectively... Having said that, MAGA.

Apologies for not seeing this sooner.
Go to YouTube and look up Elfsters Rifles and Reloading annealers, its his design.
He has videos that include what parts you need and how to build one. It's been so long since I built mine that sources and prices may be different with how things are these days. I did get everything for mine from Amazon and Ebay.

I would think different brands, even different lots, might heat up at different rates. Pretty sure I don’t want to go that far down the rabbit hole though…..
