Is this a Carbide chain ?

Hi. Seems this chain is rock hard and the file just slide on it.... is it possible it's made of Carbide  or I'm just stupid...   ;D

please see picture.

thank you

Doesn't look like a carbide tooth. It does look a bit burned from aggressive grinding which may make it hard to get a hand file to push through it easily (slightly different curvature) and hardened so file doesn't bite in like normal.
Others may know more about it. Just my thoughts.

Looks like it has been case hardened by a grinder, which will make it very hard to file.

Yup, what they said, somebody hardened it with a grinder and you will just dull files on it.
  I have gotten thru the hardening with a file but it ain't no fun.

In this case I will get a new one.  the teeth are uneven in length so there's no way I can do a good job  by hand with this chain...
I put a lot of weight on the file and it doesn't grab .... brand new file that is

thanks everyone

Someone with a light touch using a grinder can probably salvage the chain.  Light brushing strokes work much better than trying to take off a lot at a time.  When the teeth are uneven in length, it is not uncommon for me to have to reset the stop 3-4 times to get them close to the same length.  In the process of doing this, most of the hardened/blue edges should disappear.

Most of the carbide chain I have seen has carbide tips brazed to the cutter links just like circular saw blades.

Carbide coated chain is or at least was available but this isn't it. The coating looked like Spackle.
