1.2311 Tool steel

Designation

DIN:40 CrMnMo 7
AFNOR:40 CMD 8
UNI:35 CrMo 8 KU
AISI:P20

Chemical composition:

C0.40
Si0.40
Mn1.50
Cr1.90
Mo0.20

Strength:

280 - 325 HB
(≈ 950 - 1100 N/mm²)

Thermal conductivity at 100 °C:

35 W/m K


Character:

alloyed and pre-toughened tool steel, especially suitable for polishing and nitriding; high dimensional stability

Application:

cavity plates, inserts and high-tensile machine parts


Treatment by

possible:
Etching, EDM

Polishing:
excellent polishing; for higher surface requirements we recommend steel for through hardening

Nitriding:
increases the steel's wear resistance

Hard chroming:
particularly increases the steel's wear resistance and corrosion resistance


Heat treatment:

already pre-toughened; usually no heat treatment required

Nitriding:
Before nitriding, stress-relief annealing is recommended at 580 °C. (Meusburger standard)

Hard chroming:
After the hard chroming the mold must be annealed about 3 to 4 hours at 180 °C to avoid brittle fractures from hydrogen.

Hardening:
840 to 860 °C

Cooling:
to 180 °C/220 °C in oil/hot bath, then in air to about 100 °C obtainable hardness: 52 HRC

Tempering:
Slow heating to tempering temperature immediately after hardening. Minimum time in furnace: 1 hour per 25 mm part thickness

Annealing graph:


Technical tip:

  • Core strength decreases with increasing plate thickness ⇒ for thickness >300, 1.2738 is recommended.
