Application areas using Temperature Chart Recorders to record the temperature during the metal heat treatment process to maintain quality control historical data records:

Normalising

Normalising involves heating the steel to about 40°C above its upper critical limit.   The steel is then held at this temperature for a period of time and is then cooled in air. It is desirable that the temperature of the steel shall be maintained for a time period more than 2 minutes per mm of section thickness and shall not exceed the upper critical temperature by more than 50°C.

Full Annealing

Steel is heated about 25°C above the upper critical temperature, held for a set time and then cooled slowly in the furnace.  

Hardening involves heating a steel to its normalising temperature and cooling (Quenching ) rapidly in a suitable fluid e.g. oil, water or air.

This process involves heating the metal to a temperature in the range 550°C to 650°C and held at this temperature before being cooled at a controlled rate.  

Spheroidising

The process involves heating the metal to between 600°C and 650°C and holding it at at the selected temperature for a period of time.

Tempering is the process of reheating steel.
