Description
Material AISI H 11 ESR
Electro Slag Remelted Steel
High toughness combined with high working hardness, high wear resistance, extremely good caloric conductibility, good tempering properties and extremely good air hardening, water cooling possible, nitrable, good polishing qualities. Suitable for eroding. Possibly pitted by corrosion
Range of application:
Die casting, extrusion die, warm and cold shearing blades and other hot forming tools
The ESR version:
improved purity, homogeneity and toughness

(max. 770 N/mm2)
Standard analysis:
| C | Si | Cr | Mo | V |
| 0,37 | 1,0 | 5,3 | 1,3 | 0,4 in % |
Heat treatment data:
Stress-relief annealing: 650 – 680 °C
Soft annealing: 750 – 780 °C
Hardening: 1000 – 1030 °C
Quenching: Oil, air or warm bath
Tempering: 530 – 680 °C
Special heat treatment:
If the material is eroded or nitrified the tempering temperature has to be above the secondary hardness maximum. A double tempering is recommendable
