Characteristic of h11 steel material
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 steel material
H11 is always used in making die casing mould for aluminium castings,hot extrusion die and manufacturing punching tools,mandrill, mechanic
