6.Product Features:
1. High strength and toughness.
2. Great property of quenching and can be deep hardened.
3. Less tempering brittleness tendency.
4. Great machining performance under high temperature and nice appearance after machining.
5. Good performance in weld ability.
6. Excellent performance in impact absorption, such as where the hammer may bounce back and has barely any damage caused upon impact.
