WHAT IS H 13 STEEL?
It is a versatile chromium-molybdenum hot work steel.
This steel is widely used for the hot and cold work tooling applications.
Its hardness (means hot strength) resists cracking due to thermal fatigue.
Which happens due to the cyclic heating and cooling in the hot work tooling applications.
Due to its smart as well as excellent combination of high toughness and resistance to heat cracking,
H13 Steel is generally more used for hot work tooling applications than any other steel.
Similarly, it is also used in a number of tooling applications.
WHAT ARE THE APPLICATIONS OF H 13 STEEL?
H 13 Steel has a variety of applications, like:-
- Inserts, cores, and cavities for die casting dies, die casting shot sleeves, hot forging dies, extrusion dies, and plastic mold cavities and components (As all these requires excellent polish ability and high toughness).
- Also in ejector pins, nozzles

WHAT IS PURPOSE OF TEMPERING OF H 13 STEEL?
After quenching immediately temper the H 13 Steel.
The model tempering range is between 1000-1150°F (i.e, 538-621°C).
Hold the steel at the tempering temperature for 1 hr/inch (i.e, 25.4mm) of the thickness.
Then keep it for normal cooling for 2 hrs.
To maximize toughness and also the tool performance, double tempering is required.
And third tempering is often used for stress relief.
