Did I ruin my chain?

After taking my hybrid down a muddy dirt trail yesterday, I brought it home to clean it up; took off the chain and degreased it Sheldon-style.

After degreasing and rinsing, I put it directly on an electric stove burner to dry out.

In the past, I've done this at about 20% heat... this time it was at about 60%. Once I realized how hot it was, I took it off with tongs and set it aside to cool.

Some of the links have turned blue!

I let it cool down, installed it, lubed it, and it feels fine for a brief run through the neighborhood... but is it?

Didn't turn red-hot, did it? If it works, it's probably OK , assuming you got lube into all the nooks and crannies; if any old lube remained after degreasing, it was likely burned out. Don't know if I would feel comfortable in the long run (for severe hillclimbing, cross-country touring, etc.) unless a metallurgist told me the heat didn't do bad things.

You can't get true heat treating colors on steel unless you clean it to a "white" condition. What you probably did is bake off the remaining residue that was on it after degreaseing. If it's a true blue color from the heat it's what is refered to as a "spring" heat treat which would be OK. I wouldn't worry about it.

What kind of "burner"? Is it an induction top?

Most likely you screwed up the temper of the metal. Watch for increased wear rate.

I doubt you got it hot enough to justify any concerns.
