hardening a2 tool steel

Products Description

Heat treatment of d2 tool steel

Isothermal annealing:

-Heat to 870÷880°C;

-Furnace cooling to 760°Cand hold at temperature for at least 10 hours;

-Cool by 10°C/h to 720°C;

-Cooling in air.

Stress relieving:

To be carried out after machining and before the final heat treatment.

-Heat to 650-700°C, hold for 4/6 hours:

-Furnace cooling to 330-350°C;

-Cooling in air.

Hardening:

-Initial preheating to 350-450°C;

-Second preheating to 750-850°C

- Austenitizing at 1010-1040°Cor at 1080-1100°C;

-Cooling in air or in oil if large parts.

Tempring hardness: 62-66 HRC

Tempering:

In the temperature range 150-300°Cwith minimum holding time 3 h. For parts hardened

at 1080-1100°C, a first tempering will be carried out at 500-550°Cin order to exploit secon

dary hardness, followed by a second tempering at 180/300°C.

Characteristic of d2 tool steel

(1)Good quenching resistance, heat deformation small, wear-resistant, impact resistant.

(2)Vacuum degassing refining processing pure steel.

(3)Spheroidizing softening process, good cutting performance.

(4)Strengthen the elements vanadium, molybdenum special join,

is extremely excellent in wear resistance.

Application of d2 tool steel

(1)Thickness of not more than 2MM sheet, efficient blanking die, punch die and pressure die etc.

(2)All kinds of scissors, inserts, woodworking blade.

(3)Thread rolling die and wear-resistant slider.

(4)Cold Heading Die, thermosetting resin molding.

(5)Molding in deep drawing cold extrusion dies.

(6)For pounch mold,knife mold,screw mold,chinaware mold.
