[vc_row][vc_column][vc_column_text css=””]Molybdenum (Mo)<\/strong> is a heavy metal with an extremely high melting point (2610 \u00b0C), known for its ability to improve the mechanical and chemical properties of special steels<\/strong>. In particular, Molybdenum forms carbides<\/strong>, whose hardness surpasses that of Chromium carbides, making it fundamental for high-performance industrial applications.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][vc_single_image image=”45442″ img_size=”” add_caption=”yes” alignment=”center” onclick=”img_link_large” css=””][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][vc_row][vc_column]

  • Tungsten Substitute:<\/strong> Molybdenum found use in steel production as an alternative to Tungsten (W), which was difficult to obtain during World War II. Molybdenum replaces Tungsten at an approximate ratio of 1:2, meaning 1 part of Molybdenum replaces 2 parts of Tungsten.<\/li>\n
  • Hardenability and Martensite Stability:<\/strong> It increases the hardenability of steels and improves the stability of martensite at high temperatures.<\/li>\n
  • Temper Embrittlement:<\/strong> It reduces the susceptibility of steels to “Krupp sickness” (temper embrittlement).<\/li>\n
  • Fatigue and Creep Resistance:<\/strong> Significantly improves fatigue limit and creep resistance (hot deformation).<\/li>\n
  • Magnetic Properties:<\/strong> Contributes to the magnetic properties of steels, finding use in permanent magnets.<\/li>\n
  • Corrosion Resistance:<\/strong> In stainless steels alloyed with Chromium or Chromium-Nickel, Molybdenum further enhances corrosion resistance<\/li>\n<\/ul>\n[\/vc_column_text][vc_empty_space height=”16px”][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=”Diagram: Tempering Range” use_theme_fonts=”yes” css=””][vc_empty_space height=”16px”][vc_single_image image=”45445″ add_caption=”yes” onclick=”img_link_large” css=””][vc_empty_space height=”8px”][\/vc_column][\/vc_row][vc_row][vc_column]
