Dual Certification
It is common for 304 and 304L to be stocked in "Dual Certified" form, particularly in plate and pipe. These items have chemical and mechanical properties complying with both 304 and 304L specifications. Such dual certified product does not meet 304H specifications and may be unacceptable for high temperature applications.
Applications
Typical applications include:
Food processing equipment, particularly in beer brewing, milk processing & wine making.
Kitchen benches, sinks, troughs, equipment and appliances
Architectural panelling, railings & trim
Chemical containers, including for transport
Heat Exchangers
Woven or welded screens for mining, quarrying & water filtration
Threaded fasteners
