• H-13 (40 HRC)
Cutting speed : 25m/min Test piece hardness : 40HRC Test piece size (mm) : 100 x 200 x 300
APPLICATIONS: • Plastic Molds • Zinc Diecasting Dies • Short Run Aluminum Die Casting Dies • Plunger Tips, Sprue Bushings • Die Plate Strippers • Dies for Aluminum Extrusions • Pattern’s and Core Boxes • Others FEATURES: • Prehardened to 37-41 HRC. No additional heat treating required. Suited for complex molds and dies susceptible to deformation. • Good machinability • Reduced manufacturing time due to no additional heat treating. • DH2F has better wear resistance than H-13 at like hardness.
