Electropolishing For 400 Series Stainless Steel

Electropolishing For 400 Series Stainless Steel

The reason why this metal works well by being electropolished is because it chemically removes parties at a microscopic level, making the steel impervious to rusting over time, since it transforms it into a pure metal.

The 400 series group of stainless steels typically have an 11% chromium and 1% manganese increase, above the 300 series group, which causes them to be somewhat magnetic.

400 Series Stainless Steel Parts may come from…

  • Agricultural Equipment
  • Steel Plates
  • Bars
  • Sheets
  • Tubes
  • Gas Turbine Exhaust Silencers
  • Hardware
  • Motor Shafts

Looking for reliable passivation or electropolishing service for your 400 Series Stainless Steel surfaces, pieces and parts? Celco Inc has been setting the world standard since 1986 for a wide range of chemical cleaning for metals.

Benefits Of Our Electropolishing Process

The greatest benefits of this advanced finishing method include:

  • Removing microscopic burrs and leveling on the surface of machined parts.
  • Leveling the peaks and valleys that are common on metal surfaces.
  • Creating a smooth surface to reduce friction and drag.
  • Relieving stress on the surface of the component.
  • Leaving a bright, mirror-like finish on most metal alloys.
  • Providing a more easily sterilized surface.
