[vc_row][vc_column][vc_column_text css=””]Tungsten, also known as Wolfram (W),<\/strong> is a hard, heavy transition metal with a color ranging from white to steel-gray. With an atomic number of 74, Tungsten was one of the first alloying elements to be introduced into tool steels<\/strong>. Its ability to improve mechanical characteristics<\/strong> and hardenability<\/strong> makes it a crucial component in many special alloys.[\/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=”45462″ img_size=”280px” 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]

  • Increased Hardenability<\/strong>: Tungsten enhances the hardenability of steel, almost reaching the effect of nickel.<\/li>\n
  • Martensite Stability<\/strong>: It significantly contributes to the stability of martensite at high temperatures, improving thermal resistance.<\/li>\n
  • Carbide Formation<\/strong>: Like molybdenum, it forms carbides that improve mechanical properties, especially hot wear resistance.<\/li>\n
  • Substitution with Molybdenum<\/strong>: Although tungsten has similar properties to molybdenum, it has been gradually replaced by the latter in a 1:2 ratio, meaning one part of molybdenum replaces two parts of tungsten.<\/li>\n
  • Reduced Thermal Conductivity<\/strong>: The presence of tungsten reduces thermal conductivity, necessitating precautions during the heating and cooling of tungsten-containing steels to avoid thermal non-uniformities.<\/li>\n<\/ul>\n[\/vc_column_text][vc_empty_space height=”16px”][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=”Precautions for Use” use_theme_fonts=”yes” css=””][vc_empty_space height=”16px”][vc_column_text css=”” line_height=”relaxed”]\n
      \n
    • Complex Geometries and Large Dimensions<\/strong>: The low thermal conductivity can cause temperature non-uniformity, which is why accurate control of heating and cooling is essential to prevent breakages.<\/li>\n
    • Specific Applications<\/strong>: Tungsten steels are particularly suitable for applications requiring wear resistance and high hot performance.<\/li>\n<\/ul>\n[\/vc_column_text][vc_empty_space height=”8px”][\/vc_column][\/vc_row][vc_row][vc_column]
