Cold Work Tool Steel AISI A2 is a versatile, air-hardening tool steel that is characterized by good toughness and excellent
dimensional stability in heat treatment. A2 is intermediate in wear resistance
between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel. A2 provides an effective combination of strength and toughness,
tool performance, price, and a wide variety of product forms.<o:p>

Annealing: Protect the steel and heat through to 780°C.
Then cool in the furnace at 15°Cper hour to 650°C, then freely in air.
Stress Relieving: After rough machining the tool should be heated through to650°C,
holding time 2 hours.Cool slowly to 500°C then freely in air.
Hardening: 600 to 700°C. Austenitizing temperature: 790 to 850°C.
APPLICATIONS: Punches and dies, chuck jaws, cutting tools for woodworking,
tooling for plastic injection, dowel pins, hammers, industrial knives, and gage
