Nandira Chemicals is proud to offer a comprehensive line of pickling and passivation chemicals for all types of metal surfaces.
Our pickling solutions are specially formulated to effectively remove impurities, such as stains, inorganic contaminants, rust, and scale, from ferrous metals, copper, precious metals, and aluminum alloys; Passivation solutions are designed to increase the thickness of the naturally occurring oxide layer on the surface of stainless steel, improving its corrosion resistance.
Our pickling and passivation chemicals are manufactured to the highest industry standards and are safe to use with proper handling and ventilation. Our team of experts are available to provide guidance on the appropriate chemical solution for your specific metal surface treatment needs.
We are committed to providing our customers with top-quality products and exceptional customer service. Trust Nandira Chemicals for all your metal surface treatment needs. Order now and experience the difference in your metalworking process.
Pickling: Pickling is a process used to remove weld heated tinted layers from the surface of stainless steel fabrications. It provides protection to the metal surface against corrosion, pitting, and surface damage.
Passivation: Passivation process improves the corrosion resistance of the stainless steel. It removes the surface contaminants like iron and carbon impurities
SS Pickling and Passivation solutions.
Stainless steels are corrosion-resistant, but they are not completely impervious to rusting. One common mode of corrosion in corrosion-resistant steels is when small spots on the surface begin to rust because grain boundaries or embedded bits of foreign matter allow water molecules to oxidize some of the iron in those spots despite the alloying chromium. The pickling and passivation process thus help to remove those impurities and prevent further damage to the metal.

Frequently asked questions:
Q: What is pickling in the context of metalworking?
A: Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust, or scale from ferrous metals, copper, precious metals, and aluminum alloys. This is done by immersing the metal in a bath of Nandira chemical's pickling solution.
Q: What is passivation?
A: Passivation is a process in which a metal, typically stainless steel, is placed in a bath of a chemical solution to increase the thickness of the naturally occurring oxide layer on the surface of the metal. This oxide layer acts as a barrier to further corrosion and improves the corrosion resistance of the metal.
Q: What is the difference between pickling and passivation?
A: Pickling is a process used to remove impurities and stains from metal surfaces, while passivation is a process used to increase the corrosion resistance of metal surfaces. In other words, pickling is a cleaning process, while passivation is a protective process.
Q: Are there any safety precautions that must be taken when pickling or passivating?
A: Yes, both pickling and passivation involve the use of chemicals that can be dangerous if handled improperly. Proper safety precautions, such as using protective clothing and equipment, should be taken when working with these chemicals. Additionally, it is important to properly ventilate the work area and to have emergency procedures in place in case of accidents.
