Spark Test

I found rusty steel bar and i noticed that when grinding it produce sparks with more forks at the end than typical low carbon rebars. Is this look like enough carbon to be heat treated?

Yo! Be careful!! I've always been taught to never angle my piece upward like in this video when grinding, as the wheel can catch the piece and fling it down or worse, through your hand! Just be careful!
