Superior properties at elevated temperature. Excellent impact strength. Deep hardening. Readily available. Application: H*3 is an excellent choice for a wide range of hot work and cold work applications. It is used extensively for aluminu, 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. Otherapplications are, hot extrusion tooling, forging die inserts adn header dies. Machinability: The machinabilityod 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.
