Product Description
The characteristics of 304 are as follows:
1. The steel is the most easy to cold deformation strengthening. Through cold deformation processing, the strength and hardness of the steel can be improved, and enough plastic and toughness can be retained.
2.Mainly in cold processing state applied to bear high load, but also want to reduce the weight of equipment and rust free parts.
3. This steel is easy to produce work hardening when impacted by external force. It can absorb more impact energy and provide more reliable safety guarantee for equipment and personnel
