Stainless Steel Actuator Corrosion Resistance
Stainless steel pneumatic actuators excel in corrosive environments due to their chromium-nickel alloy composition that forms a protective oxide layer. The 316 stainless steel variant, with added molybdenum, offers enhanced resistance to chloride-induced corrosion.
Chemical Processing
- Resists acids (sulfuric, nitric), alkalis, and solvent vapors
- 316 SS provides chloride resistance
- Maintains integrity in harsh chemical exposure
Marine Environments
- Withstands saltwater spray and high humidity
- Ideal for offshore platforms and shipboard systems
- Prevents rust in coastal wastewater facilities
Food & Beverage
- Resists caustic detergents and chlorine sanitizers
- Complies with hygiene standards
- Endures frequent high-pressure washdowns
Wastewater Treatment
- Resists hydrogen sulfide and organic compounds
- Prevents pitting and crevice corrosion
- Outperforms standard steel in polluted water
Limitations to Consider
Stainless steel actuators may struggle in highly oxidizing environments with concentrated fluorides or extreme pH levels (below 1 or above 12), where specialized alloys might be required. However, they remain the top choice for most moderate to aggressive corrosive scenarios.
