T12 Hardware Tool Steel Bar
T12 steel due to high carbon content, after quenching more excess carbide, according to the wear resistance and hardness suitable for making impact load from the cutting speed is not high, the cutting edge is not hot tool, such as the production of lathes, Planer turning tools, milling cutters, drill bit; Reamer, reaming drill, tap, die, scraper, gauge, cut tobacco knife, file, and the section of the small cold-edge die, punching die.
