DEXITE™ SUPER SHOCK – Shock Proof Die Steel

Dexite Super Shock is the new trade name for Dexite AH Modified. Dexite Super Shock shows a low degree of distortion during heat treatment due to its chemical make-up. In many instances the chemical composition can be a significant factor in thermal response, machinability, and over all tool performance. When making the selection for which tooling material is right for your application, ask about "CLEAN STEEL TECHNOLOGY."

Consider Dexite Super Shock as a suitable upgrade for S-7 type tool steel.


• Clean Steel Technology
• Excellent Shock Resistance
• Excellent Toughness
• Good Non-Deforming Properties

Thermal Treatment Summary*

Annealing - Generally furnished annealed. Bring part up slowly (400°F/hour) to 1550°F, and hold at temperature for at least one hour/inch of greatest cross section. Slow cool in the furnace (50°F/hour) to 1000°F. Then allow cooling to continue in the furnace or still air.

Hardening - Bring up to pre-heat temperature at a rate not to exceed 400°F/hour. For large and intricate items, heat to a uniform 1150°F/1250°F, then elevate temperature to 1300°F/1400°F and hold for uniformity. Smaller and less intricate pieces may skip the first step and proceed right to 1300°F/1400°F. Take slowly to the hardening temperature of 1725°F. Hold at temperature (furnace or salt) for 30 minutes for the first inch of thickness, allow an additional 15 minutes for each additional inch of thickness.

Quenching - In air, pressurized gas, or warm oil to 150°F /125°F. Larger sections should be quenched in oil. If using an oil quench, then quench until black (900°F), cool in still air to 150°F/125°F.

Tempering - Immediately after quench, hold at temp. for 1 hour/inch of greatest cross section (2hrs min.), then air cool to room temperature. Optimum tempering temp. for cold work tools is 400°F. Resulting hardness will be approximately 57 Rockwell "C".
