How flat is ground flat stock?

Despite its name, there’s no real definitive figure regarding flatness tolerance. Instead, the “flat” in “flat ground stock” means that the material isn’t round.

How hard is ground flat stock?

Ground flat stock has a maximum hardness; this is down to its annealed condition.

Why are tool steels hard?

Due to the high levels of carbide created by tool steels, they boast fair wear resistance, toughness, and hardness. The low carbon content and moderate to high alloy are responsible for the carbide level.
