Stainless Steel Enclosure

Nema offers stainless steel enclosures in both 304 and 316 stainless steel. Enclosures made of these materials are known for tough, corrosion-resistant construction. We have the capability to build custom-sized stainless steel electrical enclosures, or you can choose a standard size NEMA-rated enclosure.

Types of Stainless Steel Enclosures

Stainless Steel Selection Guide ASTM-A240

Stainless Steel 304 (S30400)  

Low-carbon modification of type 302 for restriction of carbide precipitation during welding. Chemical and food processing equipment; brewing equipment; cryogenic vessels; gutters; downspouts; flashings.

Stainless Steel 304L (S30403)

Extra-low-carbon modification of type 304 for further restriction of carbide precipitation during welding. Coal hopper linings; tanks for liquid fertilizer and tomato paste.

Stainless Steel 316 (S31600)

Higher corrosion resistance than types 302 and 304; high creep strength. Chemical and pulp handling equipment; photographic equipment; brandy vats; fertilizer parts; ketchup cooking kettles; yeast tubs.

Stainless Steel 316L (S31603)

Extra-low-carbon modification of type 316 Welded construction where intergranular carbide precipitation must be avoided. Type 316 application requiring extensive welding.

Stainless Steel 321 (S32100)

Stabilized for weldments subject to severe corrosive conditions, and for service from 800 to 1600 F. Aircraft exhaust manifolds; boiler shells;process equipment; expansion joints; cabin heaters; fire walls; flexible couplings, pressure vessels.
