Application:
H13 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.H13 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 adn header dies.
Machinability:
The machinabilityod H13 is rated at 70 as compared to 1% carbon tool steel which is rated at 100. It also has a high grindability rating.
