Forging:
Heat slowly and uniformly to **0°C then more rapidly to
**0/***0°C. After forging 1.***9 cool slowly.
Annealing:
Anneal at **0°C and slow furnace cool. Hardness after annealing
will be approx. **5 brinell.
Hardening:Â
Pre heat the 1.***9 component slowly to **0/**0°C and
thoroughly soak. Continue heating to the final hardening
temperature of ***0/***0°C and allow the component to be heated
through. Quench in oil or cool in air.
Tempering:
Heat uniformly and thoroughly at the selected tempering
temperature and hold for at least one hour per inch of total
thickness. Double tempering of 1.***9 Â is recommended to be
carried out with intermediate cooling to room
temperature.

Hard Chromium Plating:
After hard chromium plating tempering of 1.***9 tool steel is
recommended at **0°C for 4 hours to avoid hydrogen
embrittlement. Tempering is to be performed immediately
after chromium plating.
Welding:
Due to the high risk
of crack formation welding of 1.***9 tool steel should be
avoided, if possible. When, howe ver welding is essential, the
following serves as a guide:
A.  Welding of soft
annealed 1.***9 tool steel.Â
·      Preheat to **0 - **0°C
·      Weld at ******0°C
·      Immediately stress
relieve
Electrode: Cr-Mo alloy electrode for welding structural
steel.
B.   Welding in connection
with hardening of soft annealed 1.***9 tool
steel.
·      Heat to
austenitizing temperature.
·      Cool to approx. **0°C
·      Weld at approx. **0°C
·      Cool to approx. **0°C in
the same way as at normal hardening, then temper to desired
hardness. Double tempering will
    reduce the risk of crack formation.
Electrode: Hard facing electrode.
C.   Repair welding
of 1.***9 tool steel in hardened and tempered
condition.
·      Preheat to the tempering
temperature (min. **0°C) previously used.
·      Weld at tempering
temperature
·    Heat immediately to tempering
temperature, but max. **0°C. Soaking time 2 hours.
Electrode: Hard facing electrode.
