SKU: RXSOL-68-6804-005
In Many processes used for pickling stainless steel lead to the development of hazardous nitric fumes. To improve safety when pickling, RX MARINE INTERNATIONAL has developed a unique low-fuming pickling spray which reduces the toxic nitric fumes by 50 % and increase the properties of product for optimium result.
Application
Pickling Spray is universal and suitable for spray pickling larger surfaces of all stainless steel grades. High alloyed steels and duplex steels may need more than one treatment.
Dosage

2. Stir the solution before use. Apply the Pickling Spray with an acid-resistant pump, and spray evenly over the whole surface.
3. Typical pickling time for steel grade 304/316 is 180 min at 10 °C, 90 min at 20 °C and 45 min at 30 °C. The pickling time may vary for the same steel grade, depending on the surface finish and the welding method.
4. Remove pickling residues using a highpressure water jet and then rinse with water. The waste water should be treated
before discharge.
