PROPRIETARY Unisteel 1018 Heat Treatments

Normalizing: Should be heated at 890 - 940°C and then cooled in still air.
Forging: This process requires heating between 1150 - 1280°C and is held until the temperature becomes constant. 900°C is the minimum temperature required for the forging process. The steel is then cooled in air after this process.
Tempering: Is tempered at between 150 - 200°C for improvement of case toughness. This process has little or no effect on hardness. The occurrence of grinding cracks is reduced when steel is tempered at the above mentioned temperature.
Annealing: Is heated at 870 - 910°C and allowed to cool in a furnace.
Stress Relieving: 500 - 700°C is required to relieve stress, later cooled down in still air.
Case Hardening: This process requires heating to be carried out between 780 - 820°C. Then quenched in water.
Core Refining: This is an optional process that requires heating at 880 - 920°C. After being heated is moistened in oil or water.
Carburizing: Takes place at 880 - 920°C.
