Advantages:
Resists cracking when water cooled in service.
Superior properties at elevated temperatures.
Excellent impact strength.
Availability:
Very limited.Usually available in block and plate.
Application:
H11 is an excellent choice for a wide range of hot work and cold work applications. It has excellent nondeforming properties,and is used for hot shell punches,mandrels,and applications where resistance to splitting or cracking is desirable.
Machinability:
H11 has a machinability rating of 80 compared to a 1% carbon tool steel which is rated at 100.
Annealing:
Heat slowly to 1550°F for one hour per inch of thickness. Cool 75°per hour to 1000°F and air cool. For surface protection an atmosphere furnace or stainless foil wrap must be used. The annealed hardness of H11 should be 217 Brinell maximum.
