Stainless Steel Citric Passivation
At JACO Machine Works, our certified citric acid passivation enhances durability, quality, and lifespan without altering machining dimensions, making it safe for tight-tolerance applications. Our controlled chemistry, detailed recordkeeping, and strict adherence to lot control and traceability, allow for consistent and repeatable results. Our process is certified per ASTM A967 and ASTM A380 standards, and our certification is provided free of charge.
During manufacturing, parts are exposed to contaminants such as dirt, oil, grease, and microscopic free iron particles. These non-visible particles can prevent stainless steel from forming a complete passive layer. As a result, rusting may occur on the surface of the steel components.
Citric passivation is a chemical surface treatment specifically designed to enhance corrosion resistance and mitigate the impact of environmental exposure on stainless steel parts. During the passivation process, any free iron particles that may have been deposited on the stainless-steel surface during manufacturing are removed.
Benefits of Citric Passivation
Citric passivation offers many benefits for your custom-manufactured components including:
- Improved Component Cleanliness - During citric passivation, surface impurities like dirt, oil, grease, and microscopic free iron particles are removed from stainless steel parts, resulting in cleaner components that perform better.
- Enhanced Sterilization for Medical Equipment - Surgical instruments made from stainless steel require thorough sterilization to prevent infections and ensure patient safety. Citric passivation improves the surface properties of stainless steel, making it easier to sterilize effectively.
- Higher Quality for Aerospace and Military Applications - In Aerospace and military sectors, stainless steel components must withstand extreme conditions, including exposure to corrosive environments. Citric passivation enhances the corrosion resistance of stainless steel, making it more suitable for critical applications in these industries.
- Cost Reduction and Enhanced Quality - Citric passivation reduces production costs by eliminating surface impurities, ensuring higher standards and thus resulting in fewer defects and scrap during manufacturing.
Our Process
JACO Machine Works has established a proven process which prioritizes quality throughout the entire production cycle. By meticulously pre-cleaning parts to enhance passivation effectiveness and implementing multiple post-passivation rinses in deionized water to prevent water marks, our procedures significantly enhance the durability, longevity, and aesthetic appearance of stainless-steel products. Unlike nitric passivation, citric acid passivation provides several advantages for precision parts production:
- Cost-effective way to enhance any custom stainless steel machined parts
- Environmentally-friendly processes using deionized water sources
- Removes iron without leaving any other elements in the alloy
- Yields quality results without producing hazardous waste or air pollutants
