Hardness of 1018 Steel - Annealed
Hardness of 1018 Steel - Annealed
(OP)
What are the prospects for lowering the hardness of 1018 steel to below 120 Brinell by annealing @ 1550°F? The bar is 200mm diameter.
Sorry, my ASM Metals Handbook Desk Edition is buried in my basement and I need a quick answer :(

Annealing 1018 steel forging, up to 3 in in thickness.
Annealing Temp Range
1575 to 1650 deg F
Furnace cool at 50 °F/h from 1575 deg F to 1300 deg F
Hardness
111-149 HB
I would use 1625 deg F - 1650 deg F to reach the lower hardness range of 111 HB.
