1.2312 Tool steel

Designation

DIN:	40 CrMnMoS 8-6
AFNOR:	40 CMD 8.S
UNI:	-
AISI:	P20 + S

Chemical composition:

C	0.40
Si	0.40
Mn	1.50
Cr	1.90
Mo	0.20
S	0.06

Strength:

280 - 325 HB
(≈ 950 - 1100 N/mm²)

Thermal conductivity at 100 °C:

35 W/m K

Character:

alloyed and pre-toughened tool steel, with excellent machinability in the hardened condition because of the Sulphur additive; high dimensional stability

Application:

plates for mould bases and die sets with increased requirements on strength; high-tensile machine parts

Treatment by

not recommended:
Etching, EDM

Polishing:
technical polishing possible; for higher surface requirements we recommend 1.2311 or 1.2738

Nitriding:
increases the steel's wear resistance

Heat treatment:

already pre-toughened; usually no heat treatment required

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

Hardening:
840 to 860 °C

Cooling:
down to 180 °C/220 °C in oil/hot bath
obtainable hardness: 52 HRC

Tempering:
slow heating to tempering temperature immediately after hardening; then maintain the temperature in the furnace for at least 1 hour per 25 mm part thickness
