T13A carbon is the steel with the highest carbon content among carbon tool steels. It has extremely high hardness and excellent wear resistance, but its mechanical properties are relatively low, making it unable to withstand impact.
T12 is a carbon tool steel, due to the high carbon content, more excess carbide after quenching, according to wear resistance and hardness suitable for making tools that are not affected by impact load, cutting speed is not high, and cutting edge is not hot.
