Type 304 Stainless:
This alloy is the most frequently used alloy in the stainless steel family. These alloys 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
Beauty of appearance
Ease of cleaning
Ready availability of a wide range of product forms.
Alloy is non-magnetic
This alloy is used widely in equipment and utensils for processing and handling of food, beverages and dairy products. Heat exchangers, piping, tanks and other process equipment as well as dump bodies and truck trailers. Exposure to Hydrochloric or sulfuric acid at elevated temperatures is too aggressive for this alloy.
