1/2" x 1/2" 18" OverzidedFlat Ground Stock - Air Hardening
  • DESCRIPTION

    Dimensionally stable The 5%: chromium content makes this steel especially desirable for punches and dies to be used in long production runs since it gives the tools far longer life. Up to 50% more pieces per sharpening can be produced than with oil hardening steel. High wear resistance is also ideal for punches and dies to stamp silicon, stainless steels, monel metal and other types of abrasive material. Maintains close dimensional accuracy throughout the heat treating process. The wide 75° hardening range make this virtually foolproof. Full-length identification eliminates confusion with other steels. Specifications: Furnished in 18" and 36" lengths, ground straight and parallel. Nominal Analysis (AISI A2): (Carbon -1.00 Molybdenum -1.00), (Chromium -5.25 Silicon -.40), (Manganese -.60 Vanadium -.25). Hardening Air Hardening Precision Ground Flat Stock has a wide hardening range of 1700°F to 1775°F, with 1750°F recommended for most work. For heavier sections use the high side of the range. Heat uniformly throughout but do not soak longer than necessary. Cool in still air. No preheat is required if pack or atmosphere controlled furnace methods are used, but with the open furnace method a preheat of 1450&feg;F is recommended. Tempering A Tempering time of two hours at temperature is recommended. Use chart for selecting the desired Rockwell C hardness and corresponding tempering temperature. For maximum toughness, double temper for two hours at each temperature recommended. Light Blanking Punches and Dies - 400°-425°F. Heavy Blanking Punches and Dies - 700°F. Annealing - 1525°-1575°F Furnace cool at no more than 50° per hour to 800° for maximum softness.
