Just did one and learned a little more...
I didn't heat treat the ejector before installation...which is a mistake since it's easier with it out of the gun.
The first time I heated to cherry red, then quenched in oil. I took it out and after about 60 rounds, the ejector tip started to deform a little. I figure it would have failed completely (by bulging and causing the bolt to jam) in about 300 rounds.
So I re-shaped it and heated to cherry red, HOLDING for 3 minutes at that temp. Then I quenched in oil (poured half a quart of fresh oil over it over about 30 seconds). Then I heated to get the blue color and held that for about 30 seconds.
Shot about 300 rounds through it and there is no sign of deformation, so it looks like it worked. Note that I am using steel case ammo, as most of us are with 7.62...
So there's my 2 cents...

You should look into the product Kasenit. You heat the part until cherry red, then immerse it into this stuff, then reheat to cherry red and quench in cold clean water. Really simple.
