When is stainless steel best to be used over aluminum?

Aluminum sheet metal enclosures are naturally resistant to corrosion from moisture. However, aluminum is more reactive to chemicals than stainless steel, and it may not be the best choice for an enclosure located in certain harsh industrial settings.

A sheet metal box made from stainless steel will be stronger and more resistant to dents and scratches. As it is more durable, the total cost of ownership may be lower over time.

Stainless steel is heavier than aluminum, but in many enclosure applications, weight is not an issue.

Is stainless steel sheet expensive?

Stainless steel is roughly four times as expensive as carbon steel, but stainless steel enclosures may last longer and be cost effective in the long haul. In corrosive environments, like marine air, outdoors, and around harsh chemicals, our stainless steel enclosures are often the best choice.

Stainless steel is made by adding chromium. It reacts with the air to form a super thin coating of chromium oxide, which prevents the iron in the steel from oxidizing (rusting). Chromium is expensive, which is why enclosures made from sheet metal stainless steel cost more than those made from standard steel. Nevertheless, our SNB enclosure is usually more affordable than boxes offered by competitors.

If you don’t need the corrosion resistance of stainless steel, then see this same sheet metal enclosure in standard steel, the SNB Series steel electronics enclosure. It is powder coated – a tough, paint-like coating that is cured under high heat. Powder coating gives enclosures excellent protection against occasional moisture, and helps the box continue to look good over many years of service. It provides some of the durability of stainless at less cost.

Will a steel sheet rust?

Any enclosure made with standard sheet steel may be vulnerable to rust. If the steel sheet comes into contact with moisture, then the iron in the steel reacts with oxygen. The reaction forms iron oxide, which is a fancy name for rust. In a dry, indoor environment, rust is not an issue, especially for powder coated surfaces. Bud has supplied enclosures for almost a century; occasionally we hear stories of our early steel enclosures still in service and still in great condition.
