Superior properties at elevated temperatures. Excellent impact strength. 7.die steel 1.***3, H*1 AVAILABILITY Very limited. Usually available in block and plate. 8.die steel 1.***3, H*1 APPLICATIONS H**1 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. 9.die steel 1.***3, H*1 MACHINABILITY H**1 has a machinability rating of *0 compared to a 1% carbon tool steel which is rated at **0. *0.die steel 1.***3, H*1 ANNEALING Heat slowly to ***0°F for one hour per inch of thickness. Cool *5° per hour to ***0°F and air cool. For surface protection an atmosphere furnace or stainless foil wrap must be used. The annealed harness of H**1 should be **7 Brinell maximum.
