1. Uniform product quality.
2. Increases surface wearproof characteristics
3. Increased material ftigue strength.
4. Minimum strain due to local surface hardening.
5. Minimum scale production due to rapid heating.
1. Surface hardening. 2. Heating for forging. 3. Pipe welding and post-annealing. 4. Brazing and soldering. 5. Tempering and annealing. 6. Applied heating.
