Following ASTM A380 or ASTM B600 standards, pickling consists in removing a thin layer of “metal” from the stainless-steel surface. Our range of pickling solutions pickles stainless steel and titanium. Titanium or stainless-steel pickling is the process used to remove the layers coloured by the welding of the stainless-steel and titanium products’ surface.

Following ASTM A967 standards, passivating naturally occurs on stainless-steel surfaces, but it is necessary to support the process with chemical treatments. In the context of alteration of matter by mechanical action, laser marking, etc., the quality and the thickness of the passive layer quickly increase and are optimized during the passivating treatments with acid.

Following ASTM B912 standards, the electropolishing process optimizes stainless-steel passive layer by preferentially bringing stainless-steel chromium up to the surface during the electrolysis process. This process improves the roughness of your productions and give them a shinny aspect.
