3.Heat therapy of 4140 scm440 en19
Forging
Can be heated to 1150°C and preserved until uniform
Minimal forging temperature 850°C
Can be cooled slowly in sand or ash
Tension Relieving
Hardened: Warmth to 500°C – 550°C
Annealed: Heat to 600°C – 650°C
Awesome in even now air
Annealing
Heat to 830°C – 850°C
Furnace great
Normalizing
Heat to 870°C – 900°C
Awesome in even now air
Nitriding
Warmth to 500°C – 530°C and keep for ample time to build the depth of situation required
Parts ought to be pre-hardened and tempered as needed and also pre-machined leaving a small grinding allowance only.
Tempering
Heat to 450°C – 700°C great in nonetheless air
Tempering in the selection of 200°C – 420°C triggers temper brittleness and ought to be avoided
Flame and Induction Hardening
All materia EPT consisting of de-carburized surfaces should be taken off to ensure be EPT benefits.
