Z-Wear PM Steel

Z-Wear PM Steel

Steel name: Z-Wear PM
Diagram No.: 2859
Chemical composition in weight %: 1.15% C, 7.50% Cr, 1.00% Mo, 2.40% V, 1.00% W
Steel group: PM tool steels
Properties: Z-Wear PM is a powder metallurgy tool steel intended to provide high value and exceptional versatility. It offers wear resistance superior to standard A2 and D2 grades along with high toughness and resistance to chipping. This unique combination of properties allows consistent and reliable tool performance in a broad range of cold work applications. Z-Wear is designed to be “user friendly” and exhibits excellent machinability, heat treat response (up to HRc 64), and grindability. It maintains a high degree of dimensional stability and can serve as an ideal substrate for a variety of common tool coatings and surface treatments.
Applications: General tool and die, stamping and forming tools, punches, thread rolling tools, fine blanking tools, shear blades, tooling for plastic processing.

Heat Treatment
Hardening: Methods include use of high pressure gas (minimum 4 bar preferred), salt bath, or oil. Quench rate from the hardening temperature range down to 1300°F (700°C) is critical to the development of optimum structure and properties. Part temperature can then be equalized at 1000-1100°F (540-595°C) after which cooling can continue to below 150°F (66°C) or “hand warm”. Step quenching in this manner will help to minimize distortion in larger section sizes.
Tempering: Tempering should be performed immediately after quenching. Temperatures in the range of 1000°F (540°C) to 1050°F (595°C) are generally used depending on the hardness required. Heat uniformly to the selected temperature and soak for 2 hours. Double tempering is absolutely necessary while triple tempering is recommended when hardening at 1950°F (1093°C) and over. Tempering temperatures of less than 1000°F (540°C) should not be used, and care must be taken to cool parts fully to room temperature between each temper.
