"Following quenching to hand warm, most components
should be tempered between **0 C - **0 C to remove" quenching
stresses in the case. This will have little effect on case
hardness and will reduce the risk of grinding cracks.
Hardening
Heat to **0 oC - **5 oC, hold until temperature is uniform
throughout the section, soak for *0 - *5 minutes per *5 mm
section, and quench in oil, water, or polymer as required.
*Temper immediately while still hand warm.
Nitriding
***0 hardened and tempered bar can also be successfully nitrided,
giving a surface hardness of up to Rc *0. Nitriding is carried
out at **0 oC - **0 oC, followed by slow cooling (no quench)
reducing the problem of distortion. Parts can therefore be
machined to near final size, leaving a grinding allowance only.
The tensile strength of the core is usually not affected since
the nitriding temperature range is generally below the original
tempering temperature employed.
Normalizing
Heat to **0 oC - **0 oC, hold until temperature is uniform
throughout the section, soak for *0 - *5 minutes and cool in
still air.
Stress Relieving
Heat to **0 oC - **0 oC, hold until temperature is uniform
throughout the section, soak for 1 hour per *5 mm section, and
cool in still air.
Tempering
Re-heat to **0 oC - **0 oC as required, hold until temperature is
uniform throughout the section, soak for 1 hour per *5 mm of
section, and cool in still air.
Notes on Heat Treatment
Heating temperatures, rate of heating and soaking times will vary
due to factors such as work piece size/shape also furnace type
employed, quenching medium and work piece transfer facilities
etc..
Machining
***0 in the hardened and tempered as supplied condition has good
to very good machinability and operations such as sawing,
turning, drilling, broaching, hobbing, milling and tapping can be
carried out satisfactoraly using machine manufacturers
recommendations for suitable tool type - feeds and
speeds.
