Forging:
Heat slowly and uniformly to 700°C. Forge 1.2344 within
a range of 1050/1150°C reheating if necessary, since Forging must not
be carried out below 850°C. Cool slowly, preferably in a furnace since this is
an air hardening steel.
Annealing:
Heat uniformly to 750/800°C, soak thoroughly and furnace cool.
Stress
Relieving:
After rough machining the 1.2344 components must be stress
relieved, heat to 650/700°C and hold for 2 hours then furnace cool.
Hardening:
Pre heat the 1.2344 to 750/850°C and soak thoroughly, then
increase rapidly to the hardening temperature of 1000/1030°C in a controlled
atmosphere or neutral salt bath. Cool in air.
This steel is suitable for vacuum hardening.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperature, depending
on the hardness requirement. Hold for at least two hours per inch of total
thickness and cool in air. Double tempering of 1.2344 is strongly recommended.

Tufftriding:
Tufftriding 1.2344 hot work Tool steel is
done in a special salt bath at 570°C. Holding time 2 hours. It gives a surface
hardness of approximately 950-1000HV.
Nitriding:
Nitriding 1.2344 hot work Tool Steel gives a hard surface case
which is very resistant to wear and erosion and also increases the corrosion
resistance. Nitriding in ammoniac gas at 525°C gives a surface hardness of
approximately 1000HV 1250HV. Before nitriding, the tool should be hardened and
tempered at approximately 50°C above nitriding temperature.

Welding:
Due to the high risk of crack formation welding of 1.2344 Tool
Steel should be avoided, if possible. When, howe ver Welding is
essential, the following serves as a guide:
A
. Welding of soft annealed 1.2344
X40CrMoV5 Tool Steel
· Preheat to 300 - 500°C
· Weld at 300-500°C
· Immediately stress relieve at 675-750°C. Soaking time at
temperature, 3 hours.
Electrode: Cr-Mo alloy electrode for Welding low alloyed steel.
B. Welding in
connection with hardening of soft annealed 1.2344 X40CrMoV5 Tool
Steel.
· Heat to austenitizing temperature.
· Cool to approx. 500°C
· Weld at approx. 500°C
· Cool to approx. 100°C in the same way as at normal hardening, then
temper to desired hardness.
Electrode: Hard facing electrode.
C.
Repair Welding of 1.2344 X40CrMoV5 Tool Steel in
hardened and tempered condition.
· Preheat to the tempering temperature (min. 300°C) previously
used.
· Weld at tempering temperature. Do not weld below 150°C.
· Reheat immediately to 300°C. Soaking time 3 hours.
· Cool in air to approx. 80°C.
· Reheat immediately to 300°C. Soaking time 3 hours.
Electrode: Hard facing electrode.

Machining performance
Download 1.2344 the mechanical properties of the report, the report provides detailed performance analysis and application.
Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
