Passivation of Stainless Steel at ECO Finishing

ECO Finishing is a state-of-the-art plating company in Minneapolis that provides passivation of stainless steel for a range of industries including automotive, aerospace, medical, military and manufacturers of industrial and consumer products. With over 60,000 sq ft of clean, well lit space, ECO Finishing has a streamlined plating process that complies with all EPA regulations regarding safety and waste treatment. ECO Finishing can provide both rack and barrel plating, and plate parts up to 13 feet in length for low and high volume orders.

The process of passivating stainless steel leaves a surface that is more resistant to corrosion. While stainless steel is naturally corrosion resistant, surface defects, impurities and abrasions can affect this natural resistance. Passivating Stainless Steel provides further protection and more resistance to corrosion and oxidation. ECO Finishing is compliant with ASTM-A96705 for Chemical Passivation and provides both Citric and Nitric Acid Stainless Steel Passivation.

Quality is at the heart of ECO Finishing. Each job is carefully monitored from its arrival through the entire plating process. Inspection of plated parts is enhanced by more than 100 foot candles of light throughout the entire plant. Electroplating thickness measurements are verified with X-ray fluorescence and our quality system conforms to military specifications as outlined in MIL-Q-45208. ECO uses Statistical Process Control (SPC) to assure that our product meets exacting industry standards.
