- It is annealed before ex-factory, which ensure good metallographic structure, proper hardness and good workability. There is no need to anneal again. - But It must be re-annealed if reforged, as the original organization and performance are destroyed after reforged, and the forging stress increased. - Normally it will be annealed twice and the temperature of the second annealed is 20°C lower than the first one. | |||||||||||||
