Product Dose

For Pickling This is probably the most commonly used method. Use a solution of nitric and hydrofluoric acids in water. We use ASTM A380, solution D. The formula is specified in A380 as 6 - 25% HNO3 and ½ - 8% HF in water at 70 -140 F (21 - 60 C) for about 30 minutes. This is a strong cleaning solution and may etch highly finished surfaces.

 

Coverage / kg : Approx. 100 meters of weld seam.
