Extra pure NITRIC , removes iron residue & forms an oxide layer that boosts the corrosion resistance of the stainless steel intended to improve the corrosion resistance of parts made from austenitic, ferritic and martensitic corrosion-resistant steels of the 200, 300 and 400 series and precipitation hardened corrosion-resistant steels.
Hazard: Dangerous fire risk in contact with organic materials. Highly toxic by inhalation, corrosive to the skin and mucous membranes. Uses :Organic synthesis (dyes, drugs, explosives, cellulose nitrate, nitrate salts ), photoengraving, etching steel.
PROBLEMCLEARING AGENTCOMMENTS
Rust and other corrosion products. Embedded or adhering "free ironVery light rust stain can be removed by 10% nitric acid. More significant rust or embedded iron will require picking. See also previous sections on Passivating and Picking. Sand or glass-bead blasting is another optionWear PPE as appropriate. Afterwards rinse well with clean water. Mix in acid-proof container, and be very careful with the acid, (See Precautions for acid cleaners)
Routine cleaning of boat fittings.Frequent washing down with fresh water.Recommended after each time the boat is used in salt water.
Cooking pot boiled dry.Remove burnt food by soaking in hot water with detergent, baking soda or amonia.Afterwards clean and polish. with a mild abrasive if necessary. See comments re steel wool.
Dark oxide from welding or heat treatment."Picking Paste" or picking solutions given on previous page.Must be careful rinsed, and use care in handling (see Precautions for acid cleaners).
Scratches on polished (satin or brushed) finish.Slight scratches - use impregnated nylon pads. Polish with polishing wheel dressed with iron-free abrasive for deeper scratches. Follow polish lines. Then clean with soap or detergent as for routine cleaningDo not use ordinary steel wool - iron particles can become embedded in stainless steel and cause further surface problems. Stainless steel and "Scotchbrite" scouring pads are satisfactory.

During processing operations such as forming, machining, tumbling and lapping, iron particles or other foreign particles may become smeared over or imbedded into the surface of corrosion-resistant steel parts. These particles must be removed or they will appear as rust or stain spots.
High carbon, high chromium martensitic 440C grades which are selected for high hardness and resistance may be exempt from passivation treatments at the discretion of the procuring activity.
