machined partsImprove Storage & Corrosion Resistance With Electropolishing

Screws, wheels, impellers, bolts, washers, valve stems and bodies, and other machined parts benefit significantly from electropolishing. The process provides a number of advantages, including deburring and stress-relieving of the part's surface; easy clean-up; a non-stick, non-contaminating, non-particulating finish; and a pleasing cosmetic appearance. It has been demonstrated that machined parts of electropolished 304 stainless steel exhibit superior corrosion resistance when compared to the same parts fashioned from non-electropolished 316 stainless steel. Precise ECM-like machining using electropolishing techniques is also an advantage in many applications.

Electropolishing also helps preserve carbon steel parts scheduled for extended storage. Electropolished carbon steel has been stored at 60-70 percent relative humidity for more than six months without visible rust. Electropolished brass tarnishes only slightly, if at all, under similar circumstances — a sharp contrast to buffed brass which turns dark very rapidly.
