Tool & Die Steels

DEXITE™ #14 – Oil Hardening Tool Steel

Dexite #14 is an oil hardening, non-deforming die steel which offers maximum shock resistance, combined with excellent abrasive resistance. Its ease of heat treatment and safety make this an excellent general purpose tool room steel (thermal treatment required).

Consider Dexite #14 as a suitable upgrade for O-1, L-6, or 52100 tool steels.

Thermal Treatment Summary*

Annealing - Vacuum furnace or pack in sealed container. Heat slowly to 1425°F/1450°F. Hold for 1hour per inch of thickness. Cool slowly in furnace. Expected hardness is 212 BHN.

Hardening - Heat slowly to 1750°F/1500°F. Hold for uniformity. Oil quench. Pre-heat to 1200°F/ 1250°F. Cool slowly. At 125°F/150°F begin tempering. Do not allow to cool to ambient room temperature.

Tempering - Temper immediately after quenching. Hold at tempering temperature for no less than 2 hours. Tools and punches are normally tempered at 350°F/400°F for maximum hardness.

Tempering Chart
• 800°F typical hardness Rockwell 50 "C"
• 1000°F typical hardness Rockwell 44 "C"
• 1200°F typical hardness Rockwell 30 "C"
