D3 Cold Work Tool Steel is an oil hardening, high carbon/chromium type tool steel.
> Good wear resistance
> Compressive strength
> Resistance to plastic deformation
> Good hardenability
Heat Treatment:
Forge: At 1050° C-850° C Cool slowly in furnace or thermoinsulating material
Annealing: At 800° C-850° C Cool slowly in furnace
Stress Relieving: Approx. 650° C Cool slowly in furnace
Hardening after annealing: Max. 248 HB
APPLICATIONS: Cutting tools, stamping, woodworking, drawing, deep drawing and pressing tools, cold working rolls, measuring tools.
