Features
Corrosion Resistance – 302 stainless steel provides useful resistance to corrosion on a wide range of moderately oxidizing to moderately reducing environments. The alloys are used widely in equipment and utensils for processing and handling of food, beverages, and dairy products. Heat exchangers, piping, tanks and other process equipment in contact with fresh water also utilize these alloys. Also, a large variety of applications involves household and industrial chemicals.

The 18 to 19 percent of chromium which these alloys contain provides resistance to oxidizing environments such as dilute nitric acid. These alloys are also resistant to moderately aggressive organic acids such as acetic and reducing acids such as phosphoric. The more highly reducing environments such as boiling dilute hydrochloric, and sulfuric acids are shown to be too aggressive for these materials.
