I'm guessing you're talking about high-speed steel. It's used in drill bits, router bits, taps, etc. I've been told it forges OK, but is very diffiicult to heat treat correctly. An air cool would cause it to turn brittle, and really needs a controlled heat-treat oven to prevent that.

Anyway, that's the rumor.

Might be M2 or a variant thereof. It is sometimes considered high-speed steel.
