CitriSurf Citric Acid Passivation for Stainless Steel in Australia

CitriSurf provides a revolutionary cleaning, rust removal and non-toxic passivation solution for stainless steel. The non-toxic stainless steel passivation solution utilises the natural properties of citric acid for quick, and effective stainless steel preservation. 

CitriSurf provides a high level of protection from corrosion, ensuring stainless steel maintains its sheen and remains rust-free for longer.

Although citric acid has been used to clean, remove rust and passivate stainless for many years, it is only recently we have truly been able to harness the power of citric acid for stainless steel passivation. Years of studies and rigorous testing has proved that CitriSurf products are non-hazardous and biodegradable, whilst being more effective than traditional toxic nitric acid formulations.

Reba Scientific’s range of CitriSurf passivation solutions, are user-friendly, non-toxic, safe to use, and cost-effective, making them the ideal passivation option for commercial, industrial, and residential applications. 

Why Choose CitriSurf Australia?

  • Effectiveness– CitriSurf provides excellent passivation on almost all grades of stainless steel. It removes free iron fast while providing a thicker corrosion-resistant oxide layer than with traditional toxic nitric acid solutions.
  • Ease of use – The CitriSurf passivation process works on most grades of stainless steel in less than twenty minutes, and the solution does not need to be heated, unlike nitric acid. Not only that, there is no risk of accidentally leaving the excess product for too long and there are never any nasty toxic fumes, even with poor grade stainless steel.
  • Safety –CitriSurf, which is citric based is a safer, less toxic, and a known substitute for hazardous nitric acid solutions. Nitric acid is corrosive and presents a significant danger to people and property, while CitriSurf products emit no toxic gasses and are safe for anyone to use.
  • Environmentally friendly – Because of their natural citrus composition, CitriSurf products are compatible with the environment. CitriSurf products can be disposed of in any sanitary sewage system since it does not introduce heavy metals (hazardous waste) into the bath.
  • Cost – CitriSurf provides a more affordable alternative for stainless steel passivation, as there are no expensive maintenance or waste-disposal costs. CitriSurf lasts longer and requires less product for perfect cleaning and passivation.

A Citric Acid Passivation Solution

Passivation stands as a crucial post-fabrication process for stainless steel, especially after welding, grinding, cutting, and various machining operations. Under normal conditions, several factors can impede the formation of the oxide film that guards against corrosion. 

These include foreign materials present in manufacturing environments, sulfides intentionally added to improve machinability, and particles of iron from cutting tools embedded in the surface of stainless steel parts. Passivation serves as the corrective measure for these issues. It is a meticulous process that involves removing contaminants down to the surface grain boundaries, ensuring the restoration of a uniformly corrosion-resistant surface. 

Tailored for stainless steel grades, CitriSurf leverages the power of citric acid to deliver a non-toxic and efficient passivation solution. Citrisurf addresses the challenges posed by contaminants, whilst aligning with the growing demand for ESG friendly practices and ASTM compliant products.

Frequently Asked Questions

While stainless steel inherently resists corrosion under ideal conditions, real-world factors like foreign materials, sulfides, and iron particles can inhibit the formation of the protective oxide layer on the stainless steel as a result. Passivation is a process that corrects these issues, ensuring long-term corrosion resistance and a healthier, corrosion resistant metal surface.
