FANMETAL supply the Cobalt Base Alloy hardfacing service with Cobalt Base Alloy welding rod or powder to improve the hardness and corrosion resistance of the base material including Duplex, Super Duplex , Inconel 625, Monel 400 series St and SS 316 with hardfacings of Cobalt Base Alloy* (Cobalt base) or (Nickel base) alloys.

Cobalt Base Alloy Hardfacing alloy contains 25-33% chromium, 3-21% tungsten, and 0.7-3.0% carbon. As the carbon content increases, the metallographic structure changes from hypoeutectic austenite + M7C3 eutectic to hypereutectic M7C3 primary carbide + M7C3 eutectic. The more carbon content, the more nascent M7C3, the greater the macroscopic hardness, and the improved abrasive wear resistance, but the impact resistance, weldability, and machining performance will all decrease. Cobalt Base Alloy alloy alloyed with chromium and tungsten has good oxidation resistance, corrosion resistance and heat resistance. It can still maintain high hardness and strength at 650℃, which is an important feature that distinguishes this type of alloy from nickel-based and iron-based alloys.

Cobalt Base Alloy Hardfacing Service Picture:

After machining, Cobalt Base Alloy alloy has low surface roughness, high scratch resistance and low friction coefficient. It is also suitable for adhesive wear, especially on sliding and contacting valve sealing surfaces. However, in high-stress abrasive wear, the wear resistance of low-carbon cobalt-chromium-tungsten alloy is not as good as that of low-carbon steel. Therefore, the selection of expensive Cobalt Base Alloy alloy must be guided by professionals in order to maximize the potential of the material. . There are also Cobalt Base Alloy surfacing alloys containing Laves phases alloyed with chromium and molybdenum, such as Co-28Mo-17Cr-3Si and Co-28Mo-8Cr-2Si. Due to the lower hardness of Laves compared to carbides, the material that is paired with it in the metal friction pair wears less.
