Technical specifications
FIPROSTEEL 762 is a specially formulated, sulfuric acid-based pickling agent for stainless steel, free of nitric acid; therefore, both the bath and the subsequent rinses can be easily treated in conventional physical-chemical treatment plants.
FIPROSTEEL 762 has been specifically designed as a formulation for the make-up and replenishment of a pickling bath. It delivers the best pickling performance thanks to the combined action of our FIPROPLUS 711, a hydrogen peroxide-based product.

Use
Dilute FIPROSTEEL 762 with water in a 1:1 ratio and add the product to the tank. To achieve an excellent deoxidizing result, it is recommended to operate in multi-stage treatment systems to ensure excellent cleaning of the workpieces. Immerse the workpiece to be pickled in the FIPROSTEEL 762 solution; the time required for good pickling varies from 20 minutes to over 2 hours, depending on the type of weld and the temperature.
Once the pickling operation is complete, the parts must be thoroughly rinsed with cold water. In order to guarantee an excellent final result, it will be necessary to pre-degrease the workpiece if it is soiled with oil, grease, or other impurities; for this type of application, we recommend our FIPROSTEEL 751 or FIPROSTEEL 770.
