Aisi d2 is a high-carbon, high-chromium tool steel alloyed with molybdenum and vanadium characterized by: * high wear resistance* high compressive strength* good through-hardening properties* high stability in hardening* good resistance to tempering-back. applications:aisi d2 is recommended for tools requiring very high wear resistance, combined with moderate toughness (shock-resistance). Deep drawing and forming dies, cold drawing punches, hobbing, blanking, lamination and stamping dies, shear blades, burnishing rolls, master tools and gauges, slitting cutters, thread rolling & wire dies, extrusion dies etc heat treatment soft annealing protect the steel and heat through to 1560f (850c). Then cool in the furnace at 20f (10c) per hour to 1200f (650c), then freely in air. Stress relieving after rough machining the tool should be heated through to 1200f (650c), holding time 2 hours. Cool slowly to 930f (500c), then freely in air hardening preheating temperature: 11101290f (650750c). Austenitizing temperature: 18101920f (9901050c) but usually 18301905f (10001040c).
