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.

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.
