Tool & Die Steels

DEXITE™ AH – Air Hardening, Non-Deforming, Tool Steel

Dexite AH tool steel offers excellent wear resistance, combined with good deep hardening characteristics. Its ability to show low distortion or movement in heat treatment makes this material an excellent product for many tool room applications where size stability is critical.

Consider Dexite AH as a suitable upgrade when A -2 tool steel is called out for on drawings and prints.


• Excellent Machinability
• High Compressive Strength
• Good Non-Deforming Properties
• Excellent Wear Resistance
• Good Deep Hardening Characteristics

Thermal Treatment Summary*

Annealing - Generally furnished annealed. Raise to 1550°F slowly, not to exceed 400°F/hour. Hold at temperature one hour per inch of greatest cross section (2 hour min.) Cool slowly in furnace. Do not exceed a cooling rate of 50°F/hour to 1000°F. Cool to room temperature in furnace or air; 235 BHN max.

Forging - Pre-heat at 1250°F, then to 2000°F stop at 1700°F, cool slowly.

Hardening - 1725°F/1775°F, air quench to 150°F.

Preheating - 1150°F /1250°F, raise temperature slowly, not to exceed 400°F/hour, then to 1300°F / 1400°F.

Tempering - Temper immediately. Hold one hour per inch of greatest cross section (2 hour minimum).
