C70W1 Tool Steel



Material Name


Material Name: C70W1

Characteristics and scope of application


Have higher hardness and wear resistance after quenching and tempering, but hot hardness low, quenching of poor, easy deformation, strength and ductility is low. As needed with higher hardness and wear resistance of various tools, such as simple shape of the die and the punch, metal cutting tools, drilling tools, woodworking milling cutter, countersinks, ax, chisel, longitudinal hand saw, and fitter assembly tools, rivet die grades tool.
