Cobalt-Chromium Alloy Specifications that we can made

Cobaltalloys have higher melting points than nickel (or iron) alloys ,This gives them the ability to absorb stress to a higher absolute temperature.

 

cobaltalloy give superior hot corrosion resistance to gas turbine atmospheres , this is due to their high chromium content.

 

Cobalt alloys show superior thermal fatigue resistance and weldability over nickel alloys.

 

---Excellent wear and corrosion resistance even at high temperature up to 800℃

 

SYTOP cobalt base alloys is a range of cobalt-chromium-tungsten alloys with wear resistance, corrosion and high thermal resistance. It is widely used in oil & gas, machinery, wood cutting, automotive, paper and food processing industry etc.
