Description
T8 Steel belongs to carbon tool steel. Hardened plastic mold steel. After quenching and tempering, it has higher hardness and wear resistance. But, it has a low hot hardness, poor hardenability, easy deformation, plasticity and low strength.

Features and Application
T8 steel is used for various tools that need high hardness and wear resistance. Such as simple-shaped dies and punches, metal cutting knives. Drilling tools, woodworking cutters, countersinks, axes, chisels, longitudinal hands Use saws. Fitter assembly tools, rivet dies. It is not easy to make tools that can withstand large impacts.
