Antox 73 E Extra

Pickling gel for alloyed stainless steels – extra strong

Scope of application

Removing weld scales and temper colours, old disturbed passive layers, carbon steel deposits, oxides of contaminant materials, and marks caused by handling and damage caused by heat and mechanical treatment of surfaces as well as welds. Ensures a metallically clean appearance of the surface. Intended for high-alloy chromium-nickel-molybdenum steels.

Application

Read safety instructions before use. Stir Antox 73 E Extra well until homogeneous. Apply using a spray bottle or spraying device, creating a consistent-thickness layer over welds and surfaces. Depending on the type of steel, the weld type and ambient temperature, allow to act for 30–90 minutes. Rinse with min. 12 MPa pressure water. Keep rinsing until the pickled surface and rinse water are pH neutral. If the pickled surface is not completely clean, repeat the entire process. Sometimes it is better to pickle only the welds first before pickling the entire area..

Waste water disposal

Since rinse waste water is acidic and contains heavy metals, it must be collected. The collected rinse water must be disposed of ecologically. Either use own waste water treatment plant (consult the plant operator) or engage a specialized company to dispose of it.

Caution
