Durability is a word typically used to describe stainless steel enclosures. Stainless steel is one of the strongest materials used in enclosure manufacturing and these boxes are often rated to NEMA 4X, one of the most popular NEMA standards for enclosures. NEMA 4X enclosures are well suited for wet environments and provide excellent corrosion resistance. Let’s explore what makes NEMA 4X stainless steel enclosures so popular.
Stainless Steel 101:
Stainless steel is an iron-base alloy containing 10.5% or more chromium. The chromium gives the steel its “stainless” properties—essentially corrosion resistance—by forming a very thin chromium-rich oxide layer on the surface of the metal. This chromium-rich layer prevents the steel from rusting. Stainless steel is often referred to in singular sense but there are actually over 50 stainless steel alloys. Polycase stainless steel enclosures are made from type 304, which is one of the most widely used grades. 304 stainless steel has excellent corrosion resistance due to its high percentage of chromium (18%).
Popular Stainless Steel Enclosure Applications:
There are many uses for stainless steel enclosures. One of the most common is in the food and beverage industry. The ability to withstand frequent washdowns and the hygienic qualities of stainless steel are the main reasons why these enclosures are ideal for housing food and beverage equipment. Stainless steel is naturally hygienic because is non-porous, making it virtually impossible for bacteria to grow.
The antibacterial properties of stainless steel also make it a popular choice for the medical industry. Stainless steel is prevalent in most medical implants and surgical tools. Additionally, since they can endure frequent sanitation, NEMA 4X stainless steel enclosures are often utilized in hospitals, medical centers and pharmaceutical labs.
You’ll also find stainless steel NEMA enclosures heavily used in power and energy industries, from traditional coal-powered plants to new forms of renewable energy. The corrosion resistance of stainless steel is necessary when dealing with the harsh environments these industries are located in, like coastal areas.
