Good resistance to thermal fatigue.
Superior properties at elevated temperature.
Excellent impact strength.
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.
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
