Forging:
Heat slowly and uniformly to 1000°C. Forge within
a range of 1000/800°C reheating if necessary. Cool slowly (preferably in a
furnace) to avoid setting up stresses.
Annealing:
Heat uniformly to 770°C, equalise, then furnace cool. (Hardness about 229
Brinell). Fully machined tools should be packed during annealing.
Stress Relieving:
If machining operations have been heavy or if the tool has an unbalanced
section, remove stresses before hardening by heating up to 650°C, equalise,
then cool slowly.
Hardening:
To harden 1.2510 first heat uniformly to 780/820°C until heated
through. (If possible pre-heat at 300/500°C). Allow 30 minutes per 25
millimetre of ruling section and quench immediately in oil.
Martempering:
Martempering is an alternative hardening procedure for 1.2510 which may be
used when suitable salt bath equipment is available.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperatures and hold
for at least one hour per inch of total thickness.

Hard Chromium Plating:
After hard chromium plating tempering of 1.2510 Tool steel is
recommended at 180°C for 4 hours to avoid hydrogen embrittlement
Welding:
Due to the high risk of crack formation welding of 1.2510 Tool steel should
be avoided, if possible. When, however Welding is essential,
the following serves as a guide:
A. Welding of soft annealed 1.2510 Tool steel.
· Preheat to 300 - 500°C
· Weld at 300 - 500°C
· Immediately stress relieve
Electrode: Cr-Mo alloy electrode for Welding structural steel.
B. Welding in connection with hardening of soft
annealed 1.2510 Tool Steel.
· Heat to hardening temperature.
· Cool to approx. 500°C
· Weld at approx. 500°C
· Direct re-heating to hardening temperature where after hardening (quenching)
is performed in the usual way.
Electrode: Hard facing electrode.
C. Repair Welding of 1.2510 Tool Steel in
hardened and tempered condition.
· Preheat to the tempering temperature (min. 200°C) previously used.
· Weld at tempering temperature.
· Heat immediately to tempering temperature, but max. 300°C. Soaking time 2
hours.
Electrode: Hard facing electrode.

Machining performance
Download 1.2842 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.
