IN THE FOOD AND BEVERAGE INDUSTRY, the workhorse materials are the 300 series austenitic stainless steels (i.e., S30400, S30403, S31600, and S31603). S30100 and 30200 are used, but less frequently. The 300 series alloys are used because they resist corrosion attack by most environments in the industry, are easily fabricated, do not cause contamination of the products, and are readily sanitized [1-3]. As with any industry, there are many other unique materials that are also used. In neutral or slightly acid environments where chlorides are significant, chloride-resistant stainless steel and/or other high alloy materials are used [4]. Duplex stainless steels are being used more and more frequently [5,6]. In some services like fats and edible oil, copper or copper-containing alloys should be avoided.
