Electropolishing removes a thin surface layer electrochemically, levelling peaks and leaving a chromium-enriched passive film. Mechanical polishing only abrades the surface.
| Surface Property | Electropolished (EP) Finish | Mechanically Polished (MP) Finish | Why It Matters |
|---|---|---|---|
| Internal Ra (ASME BPE) | SF4 ≤ 0.38 µm (15 µin) · SF5 ≤ 0.51 µm (20 µin) · SF6 ≤ 0.64 µm (25 µin) | SF1 ≤ 0.51 µm (20 µin) · SF2 ≤ 0.64 µm (25 µin) · SF3 ≤ 0.76 µm (30 µin) | Lower Ra resists bacterial adhesion and biofilm in sanitary loops |
| Surface Structure | Levelled, no directional lay | Directional abrasive scratches | Faster, more reliable Clean-In-Place (CIP) and Sterilize-In-Place (SIP) cycles |
| Passive Layer | Chromium-enriched passive layer | Standard passive layer unless separately passivated | Better resistance against rouging and pitting corrosion |
| Typical Specification | ASTM A270 + ASME BPE SF4–SF6 | ASTM A270 + ASME BPE SF1–SF3 | Commonly specified for regulated pharmaceutical, biotech and food-grade loops |
