Main effects:<\/strong><\/p>\n

    \n
  1. Tempering resistance:<\/strong>\n
      \n
    • Cobalt helps maintain the mechanical properties of steels stable, even after prolonged exposure times.<\/li>\n<\/ul>\n<\/li>\n
    • Thermal conductivity:<\/strong>\n
        \n
      • Cobalt promotes better heat dissipation, making it useful in steels for high-temperature applications.<\/li>\n<\/ul>\n<\/li>\n
      • Hardenability:<\/strong>\n
          \n
        • Unlike other alloying elements, cobalt increases the critical cooling rate, thereby reducing hardenability. Although it does not form carbides, it has the advantage of stabilizing martensite, which helps increase tempering resistance and promotes thermal conductivity at high temperatures.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n[\/vc_column_text][vc_empty_space height=”16px”][vc_custom_heading text=”Main applications:” font_container=”tag:h6|text_align:left|color:%235e5e5e” use_theme_fonts=”yes” css=””][vc_empty_space height=”16px”][vc_column_text css=””]\n
            \n
          • Use in super-rapids.<\/li>\n
          • Steels for hot working and for high temperature applications.<\/li>\n
          • Production of permanent magnets, thanks to the increase of parameters such as maximum induction, magnetic permeability and coercive force.<\/li>\n<\/ul>\n[\/vc_column_text][vc_empty_space height=”16px”][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=”Effect of Cobalt on Tempering Resistance” use_theme_fonts=”yes” css=””][vc_empty_space height=”16px”][vc_single_image image=”45354″ add_caption=”yes” onclick=”img_link_large” css=””][vc_empty_space height=”8px”][\/vc_column][\/vc_row][vc_row][vc_column]
