Properties of 304L (S30403) Stainless Steel
304L (S30403) stainless steel is one of the most familiar and most frequently used alloy in the stainless steel family. 304L (S30403) stainless steel may be considered for a wide variety of applications where one or more of the following properties are important:
Resistance to corrosion
Prevention of product contamination
Resistance to oxidation
Ease of fabrication
Excellent formability
Beauty of appearance
Ease of cleaning
High strength with low weight
Good strength and toughness at cryogenic temperatures
Ready availability of a wide range of product forms
Each alloy represents an excellent combination of corrosion resistance and fabricability. This combination of properties is the reason for the extensive use of these alloys which represent nearly one half of the total U.S. stainless steel production. The 18-8 stainless steel, principally Alloys 304, 304L, and 304H, are available in a wide range of product forms including sheet, strip, and plate. The alloys are covered by a variety of specifications and codes relating to, or regulating, construction or use of equipment manufactured from these alloys for specific conditions. Food and beverage, sanitary, cryogenic, and pressure-containing applications are examples.
