Chemical Compatibility of Mixer Wetted Parts
As standard, Euromixers agitators are supplied with wetted parts in 304 or 316 stainless steel. A range of plastic and rubber linings is available for corrosive or abrasive products.
The table below gives the chemical resistance of our standard steels and lining materials.
Chemical Resistance Rating
A = Excellent.
B = Good: minor effect, no significant attack.
C = Fair: moderate effect, not recommended for continuous use.
D = Severe effect: not recommended for any use.
NOTE:
The data below is compiled from published sources and is based on atmospheric pressure and an ambient temperature of 20 °C. Different operating pressures or temperatures may affect compatibility.
