What are the characteristics of induction heating surface quenching compared with ordinary heating quenching

Compared with ordinary heating quenching, induction heating surface quenching ega:

1. The heating speed is extremely fast, which can expand the transformation temperature range of body A and shorten the transformation time.

2. After quenching, extremely fine cryptocrystalline martensite can be obtained on the surface of the workpiece, and the hardness is slightly higher (2～3HRC). Low brittleness and high fatigue strength.

3. The workpiece processed by this process is not easy to oxidize and decarburize, and even some workpieces can be directly assembled and used after processing.

4. Deep hardened layer, easy to control operation, easy to realize mechanization and automation.

5. Heating and quenching of flame surface
