NITRIC ACID 69-72% 60 Kg
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.
Transparent, colourless or yellowish corrosive liquid. A strong oxidizing agent that will attack almost all metals.
Passivation Treatments
• Grades with at least 16% chromium (except free machining grade such as 303):
20-50% nitric acid, at room temperature to 40oC for 30-60 minutes.
• Grades with less than 16% chromium (except free machining grades such as 416):
20-50% nitric acid, at room temperature to 40oC for 60 minutes.
• Free machining grades such as 303, 416 and 430F:
20-50% nitric acid + 2-6% sodium dichromate, at room temperature to 50oC for 25 40 minutes
Pickling Treatments
• All stainless steels (except free machining grades):
8-11% sulphuric acid, at 65 to 80oC for 5-45 minutes.
• Grades with at least 16% chromium (except free machining grades):
15-25% nitric acid + 1-8% hydrofluoric acid, at 20 to 60oC for 5-30 minutes.
• Free machining grades and grades with less than 16% chromium such as 303, 410 and 416: 10-15% nitric acid + 0.5-1.5% hydrofluoric acid, at 20 to 60oC for 5-30 minutes.

| Rust and other corrosion products. Embedded or adhering "free iron | Very 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 option | Wear 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 cleaning | Do 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. |
