Corrosion Information
Hammond offers many different material types in its broad product offering. Deciding on the appropriate material depends on various factors with a major consideration being resistance properties of the material to various chemical laden environments. Below is a general summary of the suitability of the materials offered in Hammond’s product lines. Please consult Hammond for specific questions you may have for a particular environment.
While stainless steel provides excellent performance in most applications, there are certain environments where rust or "tea staining" may develop even on stainless steel surfaces. Some on-going surface maintenance may be required in those environments to maintain a more pristine looking surface.

Corrosion Resistance Table for Non-Metallic Enclosures
* Currently undergoing testing - this is a calculated reference.
The table provided is a guide to assist in identifying the suitability of using non-metallic enclosures in various environments. For specific suitability, prototype samples must be evaluated under actual conditions.
Hammond cannot offer guarantees of warranty as actual conditions may differ from test conditions.
Suggested Applications for Corrosion Resistant Materials
| Material Type | Hammond NEMA Rating | Suggested Application |
|---|---|---|
| Stainless Steel Type 304 | 4X | Indoor/outdoor applications. Ideal for hose-down and wet areas (e.g. food processing, water treatment, dairies, breweries, etc.) |
| Stainless Steel Type 316 | 4X | Indoor/outdoor applications. Ideal for most all environments especially marine uses. |
| Aluminum | 4 | Indoor/outdoor applications. Ideal for marine uses as well as environments containing solvents, petrochemicals, some acids and most sulfates and nitrates. |
| Fibreglass Reinforced Polyester | 4X | Indoor/outdoor applications. Ideal for continually wet, cold or salty environments. Also useful in solvent or chemical laden areas. Strong resistance to heat, dilute acids and bases, impact, fire and outdoor exposure. |
