"Resistance of Duplex SS to alkaline sequestrants"


"Does anyone have any information on whether any detrimental effects may be expected on Duplex types in general when descaling using potassium EDTA descalers? Typical situations involve pH 10-12, temperatures 60-90 deg.C, total ionic active concentrations up to 25% and contact times 6 to 24 hours."


I would not anticipate any problems with your proposed descaling procedure.
