D2 ( 1.2379 ) High Carbon Alloy Tool Steel Sheet ( Plate )

This air-hardening, cold work formulation features very high concentrations of carbon and

chromium (1.40 – 1.60% and 11.00 – 13.00%, respectively).

It’s highly wear-resistant and the high concentration of chromium imparts mild corrosion resistance.

APPLICATIONS: Rolls, punches, dies for blanking, forming, trimming, and thread rolling, shear knives,

food-processing knives, and gauges.

HEAT TREATING INSTRUCTIONS

HARDENING

Critical Temperature:

Ac1: 1449°F (788°C) Ac3: 1553°F (845°C)

Ar1: 1418°F (769°C) Ar3: 1373°F (744°C)

Preheating: To minimize distortion and stresses in large or complex tools use a double preheat.

Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1150-1250°F (621-677°C) equalize,

then heat to 1400-1450°F (760-788°C). For normal tools, use only the second temperature range as a single preheating treatment.

Austenitizing (High Heat): Heat slowly from the preheat. Furnace or Salt: 1850-1875°F (1010-1024°C).

Quenching: Air or pressurized gas to 150-125ºF (66-51ºC).

Sizes up to 4 inches (101.6 mm) in thickness will through harden when air cooled from 1575ºF (857ºC).

Sizes up to 6 inches (152.4 mm) in thickness will through harden when air cooled from 1625ºF (885ºC).

Tempering: Temper immediately after quenching. Hold at temperature for 1 hour per inch (25.4 mm) of thickness,

2 hours minimum, then air cool to ambient temperature.

The typical tempering range is 350 to 400ºF (177 to 204ºC).

For maximum wear resistance, temper between 300-350°F (149-177°C) for a hardness of 62-64 HRC.

For the optimal balance between wear resistance and toughness, temper between 500-550°F (260-288°C).

This will produce 58-60 HRC.

For maximum toughness, double temper, 2 hours plus 2 hours, at temperatures above 950°F (510°C).

This will produce hardness of less than 58 HRC.

To minimize internal stresses in cross sections greater than 6 inches (152.4 mm) and to improve stability

in tools that will be EDM'd after heat treatment, soaking times of 4 to 6 hours at the tempering temperature

below 950°F (510°C) are strongly recommended.

Annealing: Annealing must be performed after hot working and before re-hardening.

Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1600-1650°F (871-899°C),

and hold at temperature for 1 hour per inch (25.4mm) of maximum thickness; 2 hours minimum.

Then cool slowly with the furnace at a rate not exceeding 50°F per hour (28°C per hour) to 1000°F (538°C).

Continue cooling to ambient temperature in the furnace or in air.

The resultant hardness should be a maximum of 255 HBW.
