Chino Chart Recorders are used extensively to record the temperature during heat treatment of materials to maintain quality control historical data records such as in pipe welding operations & other metal heat treatment processes such as:



Normalising involves heating the steel to about 40C 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 50C.

Full Annealing

Steel is heated about 25C 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.

Stress Relieving

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


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


Tempering is the process of reheating steel.
