What is electropolishing?
All stainless steel impellers and blades from Caframo are electropolished. Electropolishing is an electrochemical treatment performed on stainless steel to obtain a smooth, corrosion-resistant finish. This process also passivates the stainless steel by removing elemental iron and increasing the chromium concentration on the surface and nickel just beneath. The result is a chemically inactive part. Note that the process does not coat the part.
Along with the improved appearance, electropolishing provides the following benefits:
• Reduces stress-related cracking and metal fatigue
• Increases the life span of the part
• Optimizes sterilization as parts are easy and quick to clean
Electropolished parts are used in the following industries:
• Aerospace and automotive
• Water purification
• Food and beverage
• Pharmaceutical and cosmetic
