ASTM B912 Electropolishing

Specification Overview

ASTM B912 defines the requirements for electropolishing stainless steel to improve corrosion resistance, remove surface contamination, and produce a bright, reflective finish.

• Removes embedded contaminants and oxide layers
• Improves surface passivity and biocompatibility
• Enhances corrosion resistance beyond standard passivation
• Applicable to grades 300 and 400 series stainless steel
