Through strict control of raw materials and constantly adjusting the process, LangFeng Metallic material Co.,Ltd has been able to stabilize production of ultra-low-iron of compound carbide powder (Fe≤0.03%), will provide a strong material foundation and improve your alloy products.
We know that iron plays a bad role in the carbide production:
First, since the carbon atomic radius and the radius of the iron atom ratio close to 0.59, the carbon in the iron solvent substitution solid solution have both interstitial solid solution, therefore, is very strong iron absorption of carbon. This will result in a non-equilibrium carbon alloy local presence, so that the alloy variant embrittlement.
Second, there is cause abnormal iron alloy. Since iron and tungsten carbide and other hard phase wettability is poor, and iron can form a solid solution with cobalt unlimited, thus, iron carbide structure and the impurity phase is undoubtedly weaken cobalt hard phase wettability.
Third, due to the presence of iron will cause movement magnetic alloy, cobalt magnetic measurement values, so that we accurately determine the magnetic alloy, cobalt magnetic difficult.
Because of the bad influence of iron carbide, carbide developed and high levels of domestic manufacturers are the raw material of iron have strictly controlled. To this end, I would strongly recommend that you double ultralow iron carbide, welcome your trial and use.
