Material Summary
The carbon content of 304H (UNS S30409) is restricted to 0.04-0.10%, which provides optimal high temperature strength.
The carbon content of 304L (UNS 30403) is restricted to a maximum of 0.03%, which prevents sensitization during welding.
The carbon content of 304 (UNS 30400) is restricted to a maximum of 0.08%. Thus 304 is not useful for corrosive applications where welding is required such as tanks and pipes where corrosive.

Applications
Used primarily for parts requiring excellent corrosion and strong magnetic properties such as:
- lead wires
- battery components
- transducers
- sparking electrodes
- heat exchangers
- implantable battery anode/connector tabs for CRM and Neurostimulation devices
- stamped or etched fabrications
1.generally export packing
-packed by knitting strips in bundles
2.It is suggested that the pipes OD under 25MM or Less than container shipment are packed by plywood cases, which can protect pipes better.
