Advantages and Features

Ground flat stock boasts many advantages, with the cutting edge sitting among the most important. This is because longevity, strong wear resistance, and durability are provided by this unique cutting edge. Additionally, the extensive list of sizes makes it easy to get your hands on your required size. As a result, wastage is minimised, meaning efficient practice can be followed. Finally, these materials are capable of handling particularly harsh temperatures and environments, thanks to their high dimensional stability.

What is ground flat stock?

Ground flat stock is a precision ground flat bar available in fixed lengths. Due to its accuracy and light tolerances, it’s often applied in toolmaking.

How hard is ground flat stock?

The annealed condition of ground flat stock means that the material has a maximum hardness.

How flat is ground flat stock?

Interestingly, the name of “ground flat stock” doesn’t come from its “flatness”. In fact, there’s no real definitive figure to measure a flatness tolerance. In contrast, the word “flat” merely states that the material isn’t round.

Why are tool steels hard?

Tool steels obtain fair wear resistance, toughness, and hardness from their high levels of carbide. These high carbide levels stem from a low carbon content, as well as a moderate to high alloy.
