316 Stainless Steel Enclosures
316 Stainless Steel Enclosure Applications
Type 316 stainless steel is an austenitic chromium-nickel stainless and heat-resisting steel with superior corrosion resistance as compared to other chromium-nickel steels when exposed to many types of chemical corrodents such as sea water, brine solutions, and other highly corrosive environments.
Since Type 316 stainless steel alloy contains molybdenum, the metal has a greater resistance to chemical attack than 304. Type 316 is durable, easy to fabricate, clean, weld, and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides, and fatty acids at high temperatures. Stainless steels containing molybdenum are required in the manufacture of certain pharmaceuticals in order to avoid excessive metallic contamination.
Type 316 stainless steel is ideal for electrical enclosures used in coastal areas, marine applications subject to sea sprays, industrial equipment exposed to corrosive process chemicals used to make such products as inks, textiles, bleaches, photographic chemicals, and rubber, and any area subject to high exposures of chloride (including de-icing salts).
316 Stainless Steel Electrical Enclosure Advantages
- Superior Resistance to Chloride - Corrosive salts can be present in many areas of the country. In addition to coastal areas, sea sprays, and salt in rainwater, heavy exposure to chloride can also be present in many parts of the country that use de-icing salts on roadways. Salt-laden roads in colder climates can sometimes create even heavier salt deposits than coastal areas. The de-icing salts become airborne via dust and road mist that allows them to travel significant distances from busy roads and deposit on surrounding structures including electrical enclosures, buildings, exterior furniture, lamp posts, etc…
- Resistance to Corrosive Chemicals - The addition of molybdenum increases the metal’s resistance to acetic, sulfuric, and sulfurous acids as well as many industrial chemicals and solvents. These types of corrosive process chemicals are used to make a wide variety of products including inks, textiles, photographic chemicals, paper, textiles, rubber, and bleaches.
- Better Resistance to Cracking & Pitting - 316 Stainless Steel offers a reduced risk of stress corrosion cracking, improved creep resistance, and better protection against pitting and crevice corrosion.

Nema Enclosures produces high-quality carbon steel electrical enclosures in wall-mount, free-standing, floor-mount, junction box, and trough types. All electrical enclosures are designed and manufactured in compliance with NEMA standards; are UL listed, and/or IP-rated. We can provide passivated stainless steel electrical enclosures whereby the metal has been coated by a protective material, such as metal oxide, to create a shell against corrosion. Passivation is also used to strengthen and preserve the appearance of metals.
Nema Enclosures electrical enclosures adhere to strict Nema Enclosures Quality Standards to ensure product performance and reliability.
Nema Enclosures fabricates quality UL-rated electrical and instrument enclosures to your exact specifications and that meet your lead times. We believe that thinking about your electrical enclosure needs while you’re configuring what goes into it will save you time, money, and frustration. Contact us today to learn how we can expedite custom enclosures and produce cost-effective safety-rated standard enclosures to protect you and your equipment.
