1.2767 Steel for through hardening

Designation

DIN:	45 NiCrMo 16
AFNOR:	45 NCD 16
UNI:	40 NiCrMoV 16 KU
AISI:	≈ 6F7

Chemical composition:

C	0.45
Si	0.25
Mn	0.40
Cr	1.35
Mo	0.25
Ni	4.00

Strength:

max. 280 HB
(≈ max. 950 N/mm²)

Thermal conductivity at 100 °C:

30 W/m K

Character:

Nickel alloyed steel for through hardening, with moderate machinability; very high resistance against bending and high compressive strength; very high toughness and good through hardenability, also with bigger sections.

Application:

high-performance cavity plates and inserts for the processing of plastics with high surface requirements (mirror finish); stamping, forming and bending dies for particularly high pressure and bending stresses

Treatment by

Polishing:
best metallurgical properties for mirror finish

is possible:
Etching

highly suitable:

EDM

not usual:

Nitriding

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

Heat treatment:

Soft annealing:
610 to 650 °C for about 2 to 5 hours slow controlled cooling of 10 to 20 °C per hour to about 600 °C further cooling in air, max. 260 HB

Hardening:
840 to 870 °C
Quenching in oil/hot bath/air
Obtainable hardness: 53-58 HRC

Tempering:
Slow heating to tempering temperature immediately after hardening. Minimum time in furnace: 1 hour per 20 mm part thickness. Tempering twice is recommended.

Annealing graph:

Technical tip:

To avoid unwanted warping during plastic injection, the tempering temperature after hardening must exceed the operating temperature by 50 °C.

Example:
operating temperature is 200 °C
tempering at 250 °C = 52 HRC
