According to NEMA 4X Standards, enclosures or wireway products, associated accessories and fittings must be made from non-corrosive stainless steel to be used in very corrosive environments. In most cases, a 304-2B Stainless Steel may be used. The primary composition of this steel is Nickel, Aluminum, and Titanium. Nickel is a superior corrosive resistant material, Aluminum adds to the resistance and polish of the surface and Titanium provides the strength that this steel is known for.

Therefore, applications of 304-2B are good for use in or around areas that have a heavy concentration of moisture such as swimming pools, commercial kitchens, food production, and some petroleum-based refining. Some of our product destinations have been to Cambell Soup, Coors Beer, Frito Lay, Pearl Beer, and Sugar King to name a few. Outside of these parameters, the use of a much more non-corrosive stainless steel would be a Type 316 2B Stainless Steel.

The Type 316-2B Stainless Steel has a larger percentage of Nickel, Chromium, and less Titanium as the requirements for more resistance to corrosion is needed and less strength is not critical. Therefore, excessive and continual corrosive particulant in the environment is further precluded from damaging the surfaces of the enclosures and wireways. Places like water plants, wastewater treatment plants, offshore drilling platforms, coastal environments, and some chemical-producing plants are good locations for use.

As a result, when NEMA 4X product is requested, it will be quoted and supplied with 304-2B Stainless Steel unless specified otherwise. Please be sure to consult drawings and engineers when bidding on projects with the above concerns. Also, check out our technical library for more info. Thanks for your business and support.
