Cold Work Tool Steel Plates AISI D-2(1.2379)

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 1560°f (850°c).
Then cool in the furnace at 20°f (10°c) per hour to 1200°f (650°c), then freely in air.
Stress relieving:
after rough machining the tool should be heated through to 1200°f (650°c), holding time 2 hours.
Cool slowly to 930°f (500°c), then freely in air
hardening:
preheating temperature: 1110–1290°f (650–750°c).
Austenitizing temperature: 1810–1920°f (990–1050°c) but usually 1830–1905°f (1000–1040°c).
