Specification of  h11 hot work die steel                                                                              

Chemical composition of  h11 hot work die steel                                                    

Characteristic of  h11 hot work die steel                                                                                 H11,is a kind of air cooling and hardening hot work die steel.In normal temperature,it smanifests excellenttoughness,preferable calorific intensity & heat fatigue and determinate abrasive resistance.

Heat treatment                                                                                                                                              

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.

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

Appcation of  h11 hot work die steel                                                                                            

H11 is always used in making die casing mould for aluminium castings,hot extrusion die and manufacturing punching tools,mandrill, mechanical press forging die,plastic mould.
