Heat Treatment Processes

Normalizing

Nominal normalizing temperature: 840-890°C
Hold the temperature for several hours
Cooling in the air

Annealing

Nominal annealing temperature: 630-650°C
Cool slowly in the furnace
Maximum Brinell hardness of 229

Hardening and Tempering (QT)

Nominal hardening temperature: 830-865°C
Hold at this temperature then quench in oil
Temper as soon as possible when temperature lowers to ambient temperature
Heat the steel carefully to a suitable temperature selected by reference to a tempering chart or table
The usual tempering temperature is 600°C depending on actual requirements
Keep the material out of the furnace, then cool in the air
