PROBLEMS WITH THIS VERSATILE OXIDIZING AGENT
For Pickling Copper and Its Alloys
For Pickling 18-8 Stainless Steel
Producers of all types of copper and | copper alloys report | that with Ferrisulsulfuric solutions they get a complete pickle . . . a clean, more natural-looking surface . . . an end to red stain . . . and substantial savings in metal previously lost in the pickling bath.
On 18-8 and on similar stainless steels, Ferrisul-HF solutions completely remove oxide scale . . . with no measurable attack on the metal... thus producing substantial savings' in metal • . . and an ideal surface for further finishing operations... all at substantially lower chemical costs.
For Pickling Straight Chrome Steels
For Pickling Copper Clad Steel
When used on straight chrome steels, Ferrisul pickling solutions have effectively removed all scale with very little, if any, metal l o s s . . . There is no fuming... The bath is easily analyzed... Chemical costs are lower than with other treatments.
By adding Ferrisul to an inhibited acid pickling bath for copper-clad steels, both red and black scale are removed in one b a t h . . . t h u s producing a quick, complete pickle . . . aiding subsequent drawing operations • •. and reducing rejects due to surface blemishes.

For Etching Steel FerrisuPs action as an etching agent is easily controlled, yet extremely rapid—as high as 30 times that of sulfuric acid • . . Thus it produces a sharp, fine-grained uniform etch . . . is now being used with outstanding success o n steel cartridge cases before drawing.
For Pickling Nickel For Etching Low Alloy Steel For Pickling Aluminum Bronze Laboratory and plant tests h a v e proved Ferrisul also has definite advantages in these treating problems, and recommended procedures have been worked out for each.
The use of Ferrisul (anhydrous |ferric sulfate) has grown rapidly in recent years, but many promising applications have yet to be explored. Dry and free-flowing, Ferrisul is easy to store, handle and use. Both the dry product and its solutions are stable, non-toxic and non-fuming.
