Chemical methods can remove high temperature oxide and iron contamination without damaging the surface finish. Electropolishing may improve the surface finish. Since they remove the surface layer by controlled corrosion, chemicals will also selectively remove the least corrosion-resistant areas such as the chromium-depleted zones.
Spot Remover aids in cleaning of stains, spots of oil, grease & other stains, annealing colorations, rust contaminations, welding marks and burns. These chemicals are also suited to clean rusted domestic fittings.
Tank immersion, spray pickling and passivation treatments should be entrusted to competent fabricators or stainless steel finishing specialists. The selection and control of these potentially hazardous processes is critical for ensuring that satisfactory corrosion resistant finishes are obtained.
Pickling/ cleaning operations following a typical manufacturing programme could be:
Main standards to abide by are:
