Product Description
Application:
1).Heat exahanger tube for petrochemical,chemical and ocean
development
2).Industrial furnace and heater tubes
3).for gas turbine and prochemical processing
4).Condenser tubes,sulfuric and phosphoric acids tubes,API tubing
5).Construction and ornament
6).Acid production,waste incineration,FGD,paper processing
industrial etc
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.
