Superior properties at elevated temperatures. Excellent impact strength. Deep hardening. die steel 1.***4, H*3 APPLICATIONS H**3 is an excellent choice for a wide range of hot work and cold work applications. It is used extensively for aluminum, zinc and magnesium die casting dies where drastic water cooling is used and both high red hardness and resistance to heat checking are crucial. H**3 is often used as a cold work shock steel because of its excellent toughness due to the low carbon content and the 1% silicon. Other applications are, hot extrusion tooling, forging die inserts and header dies. die steel 1.***4, H*3 MACHINABILITY The machinability of H**3 is rated at *0 as compared to 1% carbon tool steel which is rated at **0. It also has a high grindability rating. die steel 1.***4, H*3 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 hardness of H**3 should be **7 Brinell maximum.
