Material Resistance


Stainless steel resistance table


The corrosion resistance information contained within this table is indicative only.

All data is based on reactions noted at an ambient temperature of 20°C. Higher temperatures will generally reduce the corrosion resistance of the materials.

Check mark symbol Recommended
? Suitable, contact ACO for further advice
X symbol Not recommended
No data available

Typical factors that affect material selection:

  • type(s) of chemical(s) and % composition in the liquid
  • concentration percentages
  • contact time with trough system
  • temperatures of liquid flowing into the trough
  • flushing system employed o clear liquids from the system
  • type of cleaning agent (see Care & Maintenance)
  • grate, locking mechnism and trash basket materials
  • sealant for compatibility, if applicable

Test samples should be used for final determination of chemical resistance, contact ACO.
