Annealing 1095

[Robert Amato]

Have a few billets of normalized 1095. I have always bought everything already annealed so want to confirm this process. Sorry I know it’s been asked a million times but usually so many answers. I will be using a kiln and not a forge. And after it reaches the 1200 do I air cool from there?

Thanks

Annealing: Heat to 1475°F. Furnace cool to 1200°F at a rate not exceeding 50°F per hour.

Yes, you can air cool from there.

The problem with 1095 is that if the steel is near the transition temperature for along time the carbon can diffuse toward the grain boundaries . Large amounts of carbides in the grain boundaries , even more problem when you have continuous carbides makes for extremely brittle blades .Once you get past the transition then air cool.
