D2 Flat Ground

D2 Flat Ground,is an air-hardening, high carbon , high chromium tool steel with extremely high wear resisting properties. It is a very deep hardening steel and will be practically free from size change after proper treatment. The high percentage of chromium gives it mild corrosion resisting properties in the harden condition. D2 Flat Ground is ground to a surface finish of up to 35Ra on six sides and is free from defects and decarburization. Sold in annealed state to be heat-treated.
  • Specifications: ASTM A681, QQ-T-570, AISI D2
  • AKA: D2 flat bar, D2 premachined
  • Applications: shear blades, dies, punch plates, etc.
  • Tolerances: Thickness = +/- .001", Width = +.005/-0
  • How is it Measured? Thickness (A)  X  Width (B)  X Length
  • Available Stock Sizes: 18 inch lengths
