HEAT TREATMENT PRACTICE- BS S159
Softened: 680-700° C for 2 hours min followed by air cool - Designated S159 in annealed condition
Hardened: 1050° C (+/-10) for 30 minutes min followed by air cool
Tempered: 560 ~ 590° C for 3 hours min followed by air cool - Designated S159 in final heat treatment condition
Stress Relieve: Can be performed on hardened and tempered bars if a cold rolling operation has taken place, by holding at 30° C lower than the tempering temperature.
