Alloy 302 (also know as 18-8) is an austenitic stainless steel it provides useful resistance to corrosion on a wide range of moderately oxidising to moderately reducing environments. Alloy 302 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 in contact with fresh water also utilise these alloys. Building facades and other architectural and structural applications exposed to non-marine atmospheres also heavily utilise the 18-8 alloys. In addition, a large variety of applications involve household and industrial chemicals.
