WebJul 8, 2024 · The temperature is held for long enough to allow the transformation to occur. Any steel treated using this method has to be air-cooled. The heat-treating creates small austenitic grains whilst the air cooling produces more refined ferritic grains. The normalization process improves the strength, machinability, and durability of the steel.
