The principle of passivation<\/h2>\n

[\/vc_custom_heading][vc_column_text uncode_shortcode_id=”119563″]The passivation process accelerates the natural formation of chromium oxide, ensuring optimal surface protection.<\/p>\n

This treatment by immersion in an acid solution allows the formation of a thin layer of chromium oxides. This layer cleans and eliminates oxides and contaminating residues, thus giving the stainless steel its so-called passivation state.[\/vc_column_text][vc_custom_heading text_color=”bleu-fonce-aps” uncode_shortcode_id=”215822″ text_color_type=”uncode-palette”]The benefits of passivation[\/vc_custom_heading][vc_column_text text_color=”bleu-fonce-aps” uncode_shortcode_id=”327129″ text_color_type=”uncode-palette”]<\/p>\n

    \n
  • Corrosion resistance<\/strong>: Forming a protective oxide layer.<\/li>\n
  • Removal of contaminants<\/strong>: Cleaning of iron oxides and other residues.<\/li>\n
  • Increased durability<\/strong>: Extends the life of parts.<\/li>\n
  • Aesthetic improvement<\/strong>: Cleaner and more uniform finish.<\/li>\n
  • Preservation of mechanical properties<\/strong>: No impact on strength and ductility.<\/li>\n
  • Compliance with standards<\/strong>: Meeting industrial requirements.<\/li>\n
  • Reduced maintenance costs<\/strong>: Fewer repair needs.<\/li>\n<\/ul>\n
